Since the 1980s, the number of oil wells has increased, but the number of barrels of oil per day (BOPD) produced per well has fallen.

The first, market price of oil or gas, is governed by many elements, such as political stability, economic growth and the weather, all of which are outside the control of operators. However, the second factor, production cost, can be controlled to some degree by the industry. During the past decade, market price has stabilized—albeit at a moderate level—but production costs continue to increase. Wells cost more to drill and bring on stream because much of the easy oil is gone, leaving behind oil that defies production by conventional techniques and oil in deeper, more complex reservoirs in frontier areas. Total production costs remain high because productivity per well has declined and the techniques and materials required are generally more expensive (above ).1 Striving to remain profitable, oil companies are taking action in two areas to control costs. First, they are redefining their business, identifying core competencies and outsourcing noncore activities. Second, they are changing the way they do business, gradually converting the arm’s-length relationship with contractors into more cooperative collaborations to eliminate redundancy and boost efficiency, exploiting new technologies to enhance productivity.2 Oilfield business relationships take many forms. Volume discounts, turnkeys, service bundling, integrated services, joint ventures, partnerships, alliances—each has a place in the continuum of business practices, each with different levels of cooperation and Oilfield Review trust. Volume discounts and turnkeys are variations on the traditional way of doing business. Jobs are bid, whether by well or by project, and job specifications are set by the operator. The service company reacts, then executes the job on demand. In a second category, service bundling and integrated services are new ways of doing business that are gaining acceptance, especially outside North America. Service bundling gathers several services under one contract and concentrates the points of contact between the operator and contractors. Here, the operator still provides all the specs, and the service supplier executes the job. Integrated services contracts span a wide range of activities, from service execution—performing bundled services—at the most basic end, to product delivery at the most sophisticated end (see “Integrated Services,” page 11 ). Product delivery, in which the product may be an offshore platform, a well or some other complicated project, Entry Supply assurance Quality management entails conceptual design, process planning, service execution and evaluation. Joint ventures tend to denote shared equity and sometimes result in acquisition of one party by the other. The third category, and perhaps the newest in the oil industry—certainly the hardest to define—includes partnerships and alliances. Partnerships are defined by the Journal of Petroleum Technology as “short-term, project-specific relationships between supplier and client that seek to gain greater economic value for both parties.”3 Alliances are similar to partnerships, except they are designed to persist beyond the scope of individual projects. Other definitions exist, but an alliance is defined here as a long-term relationship between two companies that furthers their common interests over a specific range of activities. Although both are new business practices in the oil industry, alliances differ from integrated services contracts.

In an alliance, the supplier accepts responsibility to reduce client cost, and the client takes on responsibility to ensure the supplier’s profit, often by assuring future business to the supplier. The two sides work together to reduce costs and improve profitability for all involved. Trust and confidence in supplier commitment make bidding each service or per well a thing of the past. However, integrated services and alliances are not mutually exclusive. An integrated services project may be offered to an alliance partner, or may evolve into an alliance. In fact, most alliances start out as tests for a certain period of time, then if successful, may become self-renewing, sometimes called evergreen. Not written as long contracts, the terms of an alliance often fit on a single page. Alliances themselves take many shapes. An alliance may be an agreement between an operator and a service company for a single service, or it may embrace several companies or several product lines within a company to create what is called an integrated alliance. Some alliances cover one geographic area or business unit; others encompass worldwide activities. The alliance between Texaco and Dowell, for example, covers all pumping services for Texaco’s North American operations (see “DESC in an Alliance: Texaco,” page 43 ). The alliance between Oryx Energy Company and Schlumberger spans wireline, testing and logging-whiledrilling services worldwide. Service companies can form a brand of alliance among themselves—more a consortium, or partnership, following the definitions in this article—to offer complementary services when the market is for integrated services. Oil companies forge similar partnerships to develop their assets.4 “Strategic alliance” often describes alliances that are part of the partner companies’ strategies, and implies that the companies share their strategies openly. Few oilfield alliances so far have reached such a level of cooperation and openness, but that is the goal to which many aspire (left ). 4.

Hamel G and Doz YL: “Collaborate with Your Competitors—and Win,” Harvard Business Review (January-February 1989): 133. 27 While this manner of association is relatively new to the oil business, it has been practiced by other industries, notably in manufacturing, for up to 15 years. Kodak, Apple Computer, Siemens, Ford Motor Company, Motorola, Toshiba and International Business Machines are just a few of the companies with experience in gaining efficiency through alliances. Alliance analysts have a rich selection of ongoing and past alliances from which to draw analogies, along with success and failure factors (see “The Alliance as a Relationship,” page 34 ). Efficiency Improvements Through Alliances The cooperative spirit of an alliance changes the way problems are approached. In the quest to cut costs, it means not dwelling on contractor profit, but cutting total project cost (next page, top). To uncover where cuts can be made, every process in the entire project must be analyzed and examined for inefficiencies. Alliance partners construct a description, called a process map, for each process. A process map may be a list of steps or a flow chart (next page, bottom left and right ). The total project is analyzed and individual processes are retained only if they add value. Improvements are made to the remaining processes, or entirely new processes are developed, and the new processes are remapped, giving continuous improvement. 5 Decisions on how to improve a process come from the alliance partners, and team members have the power make the necessary changes. Where to start cutting costs? An economics professor would say, cut first where there are the easiest and biggest gains.6 In today’s development-oriented oil field, pumping services can often account for the majority of the cost of a well (below ). These have become the early targets of companies trying to increase efficiency. Process mapping can show where redundant efforts are undermining efficiency. For example, before one alliance, stimulation engineers from both sides would spend time designing a frac job. Soon after the start of the alliance, the engineers from both companies completed the exercise of mapping their fracture design processes. The results showed the two processes to be duplicates. 200 Thousands of dollars 150 100 50 Through the alliance, now a frac job is designed jointly, and then modeled by the service company engineer, freeing the oil company engineer to spend time on other projects that add more value—in some cases selection of other wells to be stimulated, called candidate recognition. In other cases, the optimal division of labor may assign candidate recognition and job design to the service company engineer, leaving the oil company engineer free to develop future growth opportunities. In a growing number of alliances, the oil company no longer requires a representative on site for the job. The streamlined process is more efficient, but trust in the alliance partner is crucial to the success of such a scheme (page 30 ). Eliminating bidding is another example of increasing efficiency by slashing processes that add no value. Through process mapping, some oil companies have found that almost as much money is spent on the bidding process as on the job itself. An advantage of the alliance between Conoco Canada Ltd. and Schlumberger Wireline & Testing has been the time and money saved by not bidding. Conoco Canada Ltd. previously required at least three bids for every well. Specifying the logging program took a half day; getting the bids back took another 5.

This idea was quantified somewhat by Vilfredo Pareto, an Italian economist, and founder of the “80-20 rule:” 80% of the wealth is held by 20% of the people. Quality expert Joseph Juran extended this concept to the analysis of problems in general: 80% of the problems come from 20% of the possible causes. 0 np ctio ele t g nin ea l cl sse g Ve nin lea ng i kc ess Tan c o r l ep tro oic on c Inv lids so is nt lys Pla na a rac stf ing Po s ott ort sp ep g nt al r nin me Fin lea uip eq nc tio nd ca pa Lo pre ite cs ule ed Fra sal ch po s i air ks ee dd rep flui ss 3w ing ce nd ett pro ga es ug nin ing Ga lea mm kc gra an ct pro ell Fra n lw tio dia ec ess c sel me pro ell Re lw ing m s dia log ram me ng Re rog lati ll p rre we co w nd Ne ga win vie sts ess roc Re k ac lls we en t ts tes m ce ty pj um gp nt me l co ica em Ch lop vin Mo ve De la rep gri ts os tc ns tio era op lls os gc en nte gi e elin Pip llin pu sin Ca ll We nm ts rig we t en on s co do ing an Ab Lift leti mp Co ew tm rea gn llin Dri ct Fra nRelative magnitude of cost sources in the life of a development well in a California field.

Comparing bids was a job in itself, and since there was no uniform format, this could take another day or two. After selecting a contractor, Conoco met with an accountant, then called the contractor to announce the award. “In the week I save by not bidding, I can identify new prospects,” remarks Joel Guttormsen, a geologist with Conoco in Calgary, Alberta, Canada. “That’s adding value.” An idealistic example of process streamlining through trust is the story of tubulars—drillpipe, casing and tubing. Mapping the many processes from steel manufacturing and tubular construction through deployment and finally recycling shows that tubulars are picked up, put down, inventoried and inspected anywhere from three to eight times each (next page ). Cutting out redundant steps and checks yields the seamless circle of the ideally efficient process. Most of the process lies outside the realm of the operating company alone, but through supply chain management—alliances with other links in the supply chain—total process efficiency can be optimized. Some alliances initially formed to address drilling and pumping costs later expand to enfold other services. Examples from three North American oil companies show how such alliances are increasing productivity and cutting costs. Preperforating Amoco/Dowell engineers select perfs.

Diamond Offshore Drilling was the drilling contractor, and mud was provided by M-I Drilling Fluids Company. The challenge was to drill and complete nine directional offshore wells in the Vermilion Block 331 field of the Gulf of Mexico.

Compared with other recent similar drilling projects conducted via “business as usual,“ or outside the alliance, the Vermilion 331 team increased the average drilling rate by 56% and decreased drilling costs by 14% (below ). Benchmarks were set in three areas: better-than-market financial compensation was offered if drilling time, health, safety and environment compliance, and well performance exceeded expectations. The joint team worked to anticipate time-consuming steps and solve problems rapidly. Drilling time was minimized with topdrive to speed tripping and connections, and with the help of the SPIN Sticking Pipe Indicator program, which requires downhole weight-on-bit and downhole torque as inputs.

An example is the alliance between PanCanadian Petroleum and Dowell, the goals of which are to assure high-quality stimulation and to control treatment costs. In 1992, top management at PanCanadian urged business managers to search worldwide for more efficient production methods. Out of that came the motivation to forge alliances to optimize production and speed payout ( next page, bottom ). The alliance with Dowell emphasizes finding the best technology for the problems encountered in PanCanadian’s variety of assets, which span a multitude of environments in Canada, including shallow gas wells, deep foothill exploration wells and wells producing heavy oil. A Dowell engineer—called a DESC engineer, for Design and Evaluation Services for Clients (see “The DESC Engineer Redefines 6000 6030 5000 4000 3000 2000 1000 0 32 The completion phase also benefited from the team organization and the risk-reward financial structure. By focusing attention on both productivity enhancement and process cost reduction for the 15 zones completed, the team was able to reduce average rig time by 1.8 days and shave nonrig completion costs by 10%. These savings were achieved while implementing the relatively new HyPerSTIM fracturing and sand control technique. The HyPerSTIM technology, combined with Marathon’s emphasis on sound completion practices and the team’s attention to detail, resulted in flow capabilities that averaged at least 30% more than in the prealliance completions (next page, top left ).7 While the overall project met or exceeded expectations, it took time and effort to step out of the comfort of long-standing roles, responsibilities and communication lines. A financial structure that gave all parties a vested interest in achieving project goals and an environment that promoted open communication and risk taking was key to the success of the project. 7.

A more efficient process was developed by switching to a more expensive PCM Precision Continuous Mixer system, giving higher quality fluid, and no waste. Alliance engineers also examined the type of crosslinkers in the frac fluid. Previously, they had used titanate crosslinkers with covalent bonds. Then they tried borate, with ionic bonds, which are more flexible, so not affected by shearing during passage through perforations. Finally, they switched to an encapsulated breaker to improve the breaking of the link created by the crosslinkers to start fluid flowing out of the fracture.8 The combination of new technologies yielded improved fracture conductivity (right ). In the deeper oil and gas wells, the alliance team tested a new energy-assisted, or foam, fracture technique that gave higher productivity. “We did switch to more expensive products, but they have decreased our total cost and increased our productivity. The results of the alliance surprised us,” says Steve Dole, coordinator for completions engineering at PanCanadian in Calgary, Alberta, Canada. “We thought we’d bottomed out on the cost per job by 1993. But we’ve learned we can keep cutting.” After two years, the alliance completed 1500 high-tech frac jobs, 700 cement jobs and 140 conventional fractures all with reasonable cost, excellent quality and no losttime accidents—a perfect safety record. Jobs are now scheduled to avoid delays during periods of peak activity and to make better Delayed payout Land Drilling Completion use of Dowell’s resources. This improved resource utilization has resulted in reduced costs for Dowell, thus benefiting both companies. The alliance is expanding to include coiled tubing services and cementing, and to plan longer-term actions. Through the alliance, PanCanadian is now influencing Dowell’s research in areas of special need, such as fracturing techniques for shallow gas wells and hydrocarbon frac fluid breakers.

PanCanadian has increased its drilling activity from 413 wells in 1992 to a budgeted 1250 in 1995, without increasing staff. To handle the increase in logging activity, two additional Schlumberger personnel have been dedicated to the PanCanadian office; an applications development engineer helps design logging programs, and an evaluation services technical representative coordinates all logging and testing. In an atypical exchange of expertise, a third Schlumberger engineer has been seconded to the PanCanadian petrophysics Production nPayout curves showing traditional and optimized drilling and production.

Tony Fondyga, with 15 years of wireline and testing experience, works with the geology and reservoir groups to make decisions on the fate of wells —whether to case or abandon. Working within the PanCanadian group, Tony sees the business through the eyes of the operator and deals directly with service suppliers, including competing wireline companies. During the first two years of the alliance, logging time and costs per meter have dropped relative to PanCanadian’s prealliance average. Process improvements have streamlined log data delivery by eliminating log films and delivering digital log data directly to an outsourced data library. Teamwork with the Dowell DESC engineer to analyze cased-hole logs for fracture design has led to improvements in the quality of shallow gas well treatments. Plans call for a Schlumberger interpretation specialist to move into the PanCanadian office to work on special projects and help the drilling and development groups get better value from their data.

Multiple Amoco Alliances What makes an alliance successful? From those who’ve done it, one of the first answers is top-down commitment. The alliance must have champions at the highest level. An example is the case of Amoco Production Company. Early in 1992, Amoco launched the Vendor Asset Materials Management (VAMM) team as part of a company-wide business process reengineering effort. The VAMM team, led by US Operating Group Vice-President Jerry Brown, made a presentation to the seven North American business unit managers, urging alliances as a tool for lowering investment costs and reducing controllable operational expenditures. The Amoco Supplier Alliance Program, ASAP 2000, was set in motion throughout the company to bring a systems approach to managing supplier relationships (above ). The business unit managers were encouraged to create supplier alliances with the service companies of their choice. Five alliances have been built with Schlumberger companies, and three with Halliburton Energy Services. Each alliance is different, but share some common features. “We have a healthy concern for the profitability of our alliance partners,” says Harmon Heidt, Alliance Coordinator with Amoco in Den- ver, Colorado, USA. “Our focus is on eliminating costs deemed to be unnecessary—in all our operations, Amoco’s and our suppliers.” The following examples from three Amoco business units demonstrate some of the progress to date in increasing efficiency. Early in 1992, John Morris, the operations manager of the Southeast Business Unit (SBU)—covering land operations in Louisiana, east Texas, south Texas, Arkansas, Mississippi, Alabama and Michigan—met with major service suppliers to discuss alliances. He anticipated a significant reduction in operating costs associated with reducing the number of suppliers. At The Alliance as a Relationship In French, alliance means marriage.

By the beginning of 1993, the SBU had aligned all pumping and wireline business with the Schlumberger companies. The alliance operates with a steering committee comprising the Amoco operations manager, representatives from Dowell and Wireline & Testing and the alliance coordinators. The role of the steering committee is to set objectives and communicate results between upper management and the working committee. Most alliances have two coordinators— one from the Amoco business unit and one from the Schlumberger companies. The coordinators are the facilitators for the alliance, and also responsible for scheduling, quality assessment, a newsletter for communicating results, interventions to solve specific technical problems and alliance scorecards—tools for measuring the success of the alliance. The SBU alliance is organized into four alliance field teams, each composed of Amoco, Dowell, Wireline & Testing and GeoQuest people in the office and the field. The teams select and evaluate wells, and identify and modify processes for their local operations from recompletion and fracturing to plug and abandon. Initially, there was redundancy in fracture and recompletion evaluation and design, with both sides performing the same tasks. A streamlined approach was approved by each side, and is now used in the alliance. Flexibility in job scheduling has resulted in better utilization of equipment and personnel. Comparison of well completion and fracturing costs tracked before and after formation of the alliance shows that the cooperative approach has reduced costs by 20%. Accompanying the reduction in costs is an improvement in well performance relative to benchmark wells (left ).

Daunis JR and Scott FL: “Division of Technology Ownership Between a Service Company and Customer,” paper SPE 25843, presented at the SPE Hydrocarbon Economics and Evaluation Symposium, Dallas, Texas, USA, March 2930, 1993. 35 36 Connection Time 200 150 Time, days operating in West Texas, officially began a pumping alliance with Dowell in 1992 covering cementing, acidizing and fracturing. “Substantial savings have been realized and pumping service quality has improved constantly,” reports alliance coordinator Fred Ray of Amoco, in a recent alliance newsletter. “We attribute the savings and improvements to our commodity planning and process reengineering.” Since the alliance began, the PBBU has documented a cost savings of $1.3 million. Among the greatest challenges in any alliance effort are documenting and quantifying improvement, probably more difficult in a service industry than in manufacturing. One of the most powerful tools for recording progress is the scorecard, and the PBBU alliance team takes scorecards seriously—to the point of creating a team to evaluate scorecards. Scorecards have been devised to track all activities to understand problems, identify bottlenecks and recognize improvement. Examples are scoring workover cementing jobs in categories such as cost of job, cement left in pipe, job pumped on time and remedial cement required. Often the best scorecards are the ones that look bad, because problems can be tackled only if they are discovered. And some of the most successful scorecards are those that are no longer used—either they have helped identify other factors that should be tracked, or the problems they’ve exposed have been addressed. The PBBU alliance operates through intervention teams to drive improvements to gain efficiency. “Joint intervention teams are highly focused to resolve issues in a timely manner,” says Amoco Resource Manager Ted Rolfvondenbaumen. “In other words, we involve the right people at the right time.” For example, in the past year, the fracture appraisal intervention team has reduced lost time per job from 50 to 32 minutes; replaced bagged sand with conveyed sand; switched to PCM fluid delivery; scheduled multiple fracture jobs in one day; reduced spillage to almost nothing; and brought wells on production within an average of 4.5 days, compared to 51 days in 1993. These process improvements have resulted in 17.6% cost savings for Amoco, and 5.3% savings for Dowell. A third alliance has developed with 100 50 0 1991 Amoco 1994 Industry 1994 Amoco nReduction in connection time—from well spud to product sales—for Amoco’s Greater Green River basin. Amoco’s Northwest Business Unit (NWBU). The NWBU comprises six basins straddling the Rocky Mountains in Colorado and Wyoming. In 1993, the NWBU’s Greater Green River basin group formed an integrated alliance to maximize value from the remaining exploitation opportunities in a 20-year-old field. The alliance united the efforts of Amoco, Dowell, Wireline & Testing, Exeter Drilling, Apex Mud and Cooper Wellheads. Since then the agreement has been extended to include three other fields. The major objectives were to reduce total system costs for drilling and completion, reduce cycle time and continuously improve service quality. The alliance steering committee set incentives for recognition of innovative and superior work at three levels: individual, team and company. To monitor progress, the committee established measures—well performance, well cost, service quality, timing and adherence to plan. Total well costs in the first field dropped 49% compared to 1991 levels, an achievement made possible by numerous changes in the drilling and completion process. Amoco completely redesigned the wellhead assembly, facilities and casing size to shave costs. The drilling contractor improved the drilling process to reduce average drilling time per well by six days. Alliance partners modified frac fluid and proppant, taking advantage of the BRACKETFRAC technique in which both buoyant and dense proppant are injected to create artificial barriers above and below the desired fracture interval, thereby controlling fracture height. Dowell engineers used the FracNPV application that examined the balance between fracture cost and anticipated production to identify the most cost-effective fracture treat- ment. Dowell supplied coiled tubing services to eliminate the need for a service rig and exploited used coiled tubing as costeffective production tubing. Fracturing costs per volume of gas produced have been reduced by an average of 57% compared with prealliance fracs. Connection time—time from spud to first sales —dropped 66% (left ). News of the project’s success has spread, and other operators in the region have approached Amoco with proposals to turn portions of their operations over to Amoco to optimize production. Alliances in Research and Development Not all alliances between oil and service companies revolve around field operations. Collaboration and optimization of resources are being taken a step further with research and development alliances. Through such alliances, the oil company benefits by obtaining the tools and products for their precise needs. In addition, the service company develops products that can be transferred to the market, and the companies exchange know-how. An example of such an alliance is the collaboration between AGIP, the Italian oil company, and Wireline & Testing and GeoQuest. In 1992, Agip sought a working relationship with a service company to enhance the usefulness of dipmeter logs by automating more of the interpretation and integrating it with other log data. Agip wanted more than a typical operator-contractor arrangement, in which the contractor programmers would meet Agip’s specifications: working together, geologists and programmers from both sides created a product adapted to user needs. The project was named DipFAN for dip facies analysis, and split into six modules. For three of the modules, Agip engineers are assuming the role of operator, taking the project lead with responsibility for specification and design documents, executable code and a user guide, while their Schlumberger counterparts take the role of partner. For the other three modules, the roles reverse. Four of the modules have developed to field-test stage, and work began on the remaining two early in 1995. All six modules will become part of the GeoFrame oilfield data interpretation system (see “Tapping the Dipmeter,” next page ). Another example of a development alliance is the agreement between Statoil, the Norwegian oil company, and Geco- Oilfield Review Tapping the Dipmeter DipFAN facies analysis consists of software modules for faster, standardized interpretation of dipmeter data. By year end, six modules will be completed and running on the GeoFrame system. Three of the modules have been completed: the StatPack, FasTex and SediView applications. The StatPack program is both a stand-alone module and a statistical library used by the other components of DipFAN. It performs basic processing such as principal component and cluster analyses. FasTex processing conducts geology-driven pattern analysis of high-sampling rate resistivity data from the dipmeter to extract layering, heterogeneities and fractures. Texture curves are generated by cluster analysis to define a high-resolution electrofacies zonation. The program outputs a catalog of facies in the specified interval, and segments the interval into layers with those facies (top, right). SediView analysis processes dip information to produce a sedimentological description of the logged interval (bottom, right). The method first ■FasTex pattern analysis for clustering dipmeter data into a specified number of layers—five in this case. The geologist can cross-plot variables such as volume, apparent thickness or contrast of conductive events versus resistive events, to monitor the quality of clustering (left). The resulting vertical zonation is displayed with representative examples of each zone, identified by their eight dipmeter channels (right). requires making a link between lithological information and dip results. Then the structural dip is computed and subtracted, to rotate the sedimentary bodies to their initial position. The final step detects the boundaries and orientation of the sedimentary structures. ■SediView analysis of dip information to produce a sedimentological description of the logged interval.

The new system places four sensor components on the ocean floor and records signals from a conventional marine seismic source. This allows recording of shear waves, which have previously been recorded only on land (see “Why Subsea Seismics?” below ). Shear wave analysis adds information about rock and fluid boundaries that eludes conventional compressional-wave seismic interpretation. Statoil had already invested years to research the SUMIC technology, including three feasibility studies, scaled experiments and comparison of the sensors with reference sensors in controlled environments. It was time to find a contractor to help commercialize the system. After considering several companies, Statoil selected Geco-Prakla to develop and improve the equipment and associated services, and promote marketing and sales. The agreement permits Statoil to retain ownership rights on the technique, while Schlumberger has exclusive user rights. The agreement is one of a collection of projects under a wider umbrella agreement with Statoil. In a separate project for processing and interpretation, new functionality will be added to the Charisma seismic workstation to handle the new type of data. The Hard Road to Alliances There are no short cuts to alliance success. Process mapping can be a tedious exercise. Meeting after meeting to explain total quality management and to ensure continuous improvement can make office life more demanding. The alliance approach requires learning a new way to work, and it raises some difficulties and questions. The foremost problem has been securing top-level commitment and top-to-bottom buy-in to the alliance concept. For alliances to work, they must be part of the business plan, not a passing fad. An alliance is not a short-term fix. There may be early successes that are not repeatable. Large cost savings encountered in the first rounds of continuous improvement may have caught what alliance specialists call “no-brainers,” or “low-hanging fruit”—the easy fixes that yield big savings. Later savings may be incremental, but still important, and not attainable if the alliance partners give up too quickly. There is also a fear of change. People are going to be concerned about their careers, their power and their control. These very delicate, significant issues must be considered before an alliance is formed. Restructuring is not a necessary outcome of an alliance. According to Rick Adams, Operations Engineer for Mobil Exploration & Pro- Why Subsea Seismics?

The acquisition of S-wave data may solve many Receiver groups problems encountered in conventional marine seismic surveys. Compressional waves are disrupted by changes in fluid content, especially the pres- S wave ence of gas, in subsurface layers.

Seismic wave energy ducing, in Midland, Texas, “Alliances are a way of improving productivity without the negative side effect of downsizing.” Another potential concern is the fear of being locked into an agreement and not getting the best technology. This must be taken into account when choosing a partner. The alliance partner that has offered the best technology in the past and who offers it today is likely to be the one who will be able to offer it in the future. Oil companies may question how big they must be to have an alliance. According to industry experts, alliances can work for small independents as well as for majors. The goal is to optimize assets, maximize efficiency and lower total costs. An operator’s assets may be its infrastructure, or a large in-house staff. Or it may have a small in-house staff that needs to be augmented. As more companies begin to make alliances, some are looking for ways to share their experience and to promote alliancing as a new technology. Others are beginning to view alliancing as a core competency, and are less inclined to share their expertise. They have worked hard to learn the skills, and are more reluctant to give away their new competitive advantage. But such an advantage may be temporary. New business relationships that control total costs and encourage constant change are healthy for the industry, and give a direction for more companies to follow. Through alliances, operators and service companies are trying to achieve a common goal—lower the total cost per energy unit produced. As more companies gain experience with alliances, significant savings will continue to be made by both operators and suppliers, and more opportunities will be found for gaining efficiency and adding value. —LS is greatly attenuated by reflection at large-contrast boundaries. In conventional surveys, waves reflect twice—going down, then up again—at the waterrock interface. Compressional- and shear-wave recordings both may benefit from the placement of receivers on the seafloor. Finally, the new technology may facilitate repeat surveys designed to monitor changes in fluid saturation fronts. In the past, such surveys have suffered from difficulties associated with changes in acquisition geometry and equipment and in processing methods between one survey and the next. Permanently secured sensors may alleviate some of those difficulties. 1.
