Real-Time Monitoring
RMSReal-Time provides geoscientists and engineers with an
integrated solution to monitor real-time drilling data within the
3D geological model. Combined with state-of-the-art RMSTM
functionalities for target picking, trajectory planning and model
update RMSReal-Time greatly improves the decision making
process at the time of drilling.
IN SUMMARY
• Team collaboration is greatly improved when live log data
is viewed in RMS together with the geological model.
• Monitoring is made easy by the use of alarms.
Real-Time Monitoring using WITSML
• Instant re-planning of the well path while monitoring
drilled data in real-time.
While drilling, real-time data from the rig containing
information about the well path and the logs can be imported
directly into RMS using the WITSML system. The real-time data
can be co-visualised into multiple views in combination with
elements of the geological model.
• Predict the log response while well is being drilled.
• Using the Geosteering Diagnosis panel, risk is reduced by
keeping errors under control thanks to alarms. Permanent
monitoring of the proximity between the well and the
objects in the model.
• Comparing real-time log data with synthetic logs is a key
factor in reducing uncertainty and improving wellbore
placement.
• Project to bit methods are available to allow for the
accurate display of the bit position.
Real-time 3D Drilling Diagnosis and Rapid Model
Updating
Well planning and access to real-time data has been available in
RMS for several years. However, the utilisation of the data has
been further improved with the new real-time monitoring
functionality now available with the RMSReal-Time module since
2009.
Geosteering Diagnosis Panel with Alarm System
The new Geosteering Diagnosis panel is an excellent tool to
analyse the current position of the well and the properties of
the rocks being drilled through relative to other data in the RMS
project. This knowledge is then used to continuously adjust the
drilling strategy. Any number of rules can be defined and alarms
triggered when approaching objects like horizons, contacts,
faults, targets or a log value. This makes monitoring the
operations easier, and risk and errors can be drastically reduced.
Real-Time Monitoring
Estimated Log Response in the Planned Well Position
Another new and very useful feature for analysing a well being
drilled is the possibility to estimate the log response, e.g. gamma
ray values, in the position of the planned well. This calculation is
based on a 3D parameter, or the log response in selected wells and
the stratigraphic position of the planned well. Comparing
real-time log data with synthetic logs is a key factor in reducing
uncertainty and improving wellbore placement.
Planned Ahead Trajectory
RMS can calculate a Planned Ahead trajectory from the current
position using RMSWellplan technology. The Planned Ahead
trajectory can be updated in real-time, and adjustments can be made
to make sure targets are hit.

Correct Display of Logs and Project to Bit Caculation
To make the right decisions it is imperative to display the data
correctly. The distance between the tools measuring the log
responses and the bit can be defined to ensure accurate display of
log data. The possibility to define the exact position of the bit is
now available.
Real-Time Interpretation and Model Update
Roxar 2014
A unique capability of Roxar’s workflow is the ability to rapidly
update the reservoir model locally around the well. In addition to
the more normal methodology of rerunning the entire modelling
workflow, which can be time consuming and may result in updates
away from the well, RMS includes tools for the local updating of
both the structural model and the property model. These allow for
very local adjustments to be applied in real-time without making
undesirable adjustments to the rest of the reservoir model. This
ensures that decisions can be made based on the latest acquired
data.
