Whale Oil, Kerosene and the “Oil Industry”
In the 1800’s, whale oil was popular for lamps and candles,
but expensive. ~15,000 right Whales killed/yr in early 1800’s

250 whales killed at Point Lobos between 1862 – late 1870’s
In 1857, clean burning kerosene (originally called “coal oil”) lamps put
on market. Rapid expansion by 1860 in US, eventually leads to the end
of whale oil lamps/candles.

Known recoverable US reserves is ~21 billion barrels and US
consumes ~22 million barrels/day.
“Reserves” = known amounts that can be profitably developed
at current prices and costs, using current technologies and
under current rules (institutional resources)
Reserves increase in response to:
•

•
•
higher prices
lower costs of development
technological improvements
new discoveries
without any change in the quantity in the ground
The size of reserves depends on economic factors, not on
the physical amount in the ground.
The semi-submersible rig Deepwater Horizon, drilled the Tiber well
in the Gulf of Mexico. Water depth = 4,132 ft or 1,259 meters.
Total depth of well ~35,055ft or ~10.7km or ~6.6 miles,
deepest well in history. Could yield 400,000 – 650,000 bpd
An explosion on 4/20/10 killed eleven crewmen. On 4/22/10
Deepwater Horizon sank, leaving its well gushing causing the

What are fossil fuels?
• Oil, Natural Gas, and Coal
Total World Oil Reserves
Conventional vs Unconventional
• Derived from remains of organisms which decompose and are
exposed to heat and pressure beneath the Earth’s surface over
millions of years.
• Consist primarily of hydrocarbons: organic compounds of H and C
atoms with smaller amounts of O, S and N. The approximate length
range for “oil” is C5H12 to C18H38. Any shorter hydrocarbons are
considered natural gas, the simplest form is methane CH4.
• Petroleum (Petra-rock / Oleum-oil) /Crude Oil: complex mixture of
liquid hydrocarbons of various lengths. Termed 1st used and published in 1546 by
German geologist/mineralogist Georg Bauer aka Georgis Agricola
Why use Oil?
•
•
•
•
•
•
•
•
It burns
Yields lots of energy
It’s relatively cheap
It flows
Easy to extract or pump it out
Easy to transport
Not much land disruption
It’s abundant
At end of 2011, world proven crude oil reserves stood at over
>1.4 trillion Barrels (~1,482 billion barrels)
1,481,526
• can be converted to useful materials
Refining Crude Oil
• Heating / distilling separates crude oil into
components with different boiling points
• Lightest components rise: petroleum gases,
gasoline. Then kerosene (used as jet fuel),
heating oil, and diesel fuel for trucks, buses,
trains, and ships. Heaviest fractions stay at
the bottom of the column: lubricating oils,
waxes and asphalt.
Petrochemicals are products of oil
distillation, over 4,000. Common
“end-products” are pesticides,
plastics, fibers, paints, synthetic
rubbers and medicines

Why use Natural Gas?
A bi-product of oil & coal used as fuel, and
in smelting iron ore
Mostly methane, ethane, propane, butane
•
•
•
•
Burns hotter than oil
It’s cleaner than oil
Easy to extract
Easy to transport
• Yields lots of energy
*Includes both home heating oil and diesel fuel
• Global reserves up 140% since 1973
• Not much land disruption
**Heavy oils used as fuels in industry, marine transportation, and for electric power
generation (Source: American Petroleum Institute)
Disadvantages of using Oil & Natural Gas?
• Often degrades fresh air, soil and water
• Emits greenhouse gases (CO2, CH4) and other
damaging gases (CO, NOx, SOx, H2S)
• Gases contributes to global climate change

Investigators found that pilot John Cota of the Costco Busan
abandoned his radar because he was high on pharmaceuticals.
On March 6, 2009, A plea agreement was negotiated with
prosecutors to charges of federal water pollution and
migratory bird killings.
He was sentenced in July 2009 to 10 months imprisonment
and fined between $3,000 and $30,000. He’s currently
trying to pilot again.
Pilots now earn $451,000 /yr & Cota’s pension is ~$228,864/yr

Origin of Oil?
Most commercial oil is probably “organic oil”
How can this happen?
• Forms in marine basins with rich diversity of microscopic algae,
protozoa and animals (plankton) living on the surface
• Organisms die, settle onto ocean floor --> some decomposition
occurs -->depletion of O2 in bottom waters
-->decay slows or ceases.
• Pressure and heat build up as organic material is buried under many
layers of sediment. This converts the organic molecules to kerogen
(solid, waxy organic matter in sedimentary rock, too thick to flow out of rock).
Geothermal Gradient: 20 degrees C/km, 68 degrees F/km or 109 degrees F/mi
How do “Conventional” oil fields/petroleum pools/ aka
“Oil Traps” form?
1) Need Source Rock (different
types)
(sedimentary layers originally containing
organic C)
2) Need burial / Heat and Pressure
applied to source rocks to promote
Kerogen conversions
3) Concentrate petroleum into a pool-> HC compounds can Migrate
from source rocks into rocks that
can become saturated with
petroleum.
4) Need Reservoir Rock: permeable
rock whose pore space is saturated
with oil/gas
Kerogen / Oil Formation
• Kerogen, highly viscous, complex molecules (“Tar”) forms first,
at temperatures <30º- ~100ºC @ ~ <1-3km depth.
Kerogen can then convert to various liquid hydrocarbons at
temperatures ~80ºC - 120ºC (sometimes wider) @ ~ 3-8km depth. is
The process of breaking a long-chain of hydrocarbons into short ones =
“Cracking”.
• At temperatures > 100ºC (212ºF), liquid petroleum can be converted
into a variety of natural gases such as methane, ethane, propane and
butane each type more complex and heavier molecules.
• At temperatures of ~200ºC (400ºF) and/or depths of > 10km, methane can break
down completely and the rocks no longer contain hydrocarbons.
• Limited window of opportunity for the conversion of organic remains to
hydrocarbon fuels
How do oil fields/petroleum pools form?
5) To accumulate a pool, the
HC must be trapped in the
Reservoir Rock:
Need Cap Rock:
impermeable layer that
halts migration of fluids
(e.g. shale, salt deposit)
Common “Oil Traps”
include anticlines,
faults, salt domes &
stratigraphic
and one last thing……..>>>>
Is petroleum formation likely to happen again soon?
• No.
• No petroleum found in rocks younger than 1-2 million years so it’s
extremely likely it takes at least this long for petroleum to form.
• It’s estimated that <0.1% of all marine organic matter buried on the
sea floor is eventually trapped as usable petroleum.
• Some settings lack adequate heat to convert kerogen to petroleum
• Some settings lack sufficient depth or the necessary cap rock to
burry and trap fluids from escape.
• Conditions required to produce, concentrate, trap and retain
hydrocarbons are rarely observed together--> most marine
sedimentary rocks lack petroleum.
• Geologic processes can destroy oil traps. Uplift, erosion and faulting
can remove cap rocks or rupture traps allowing oil or gas to escape at
the surface. Majority of current oil reserves are in rocks < 160 my
old. 90 &150my common
• >90% of all petroleum formed escapes @ Earth’s surface.
7
Abiotic Oil?
Some challenge the accepted view of petroleum formation being
exclusively from biological material.
Extraterrestrial occurrences used to support hydrocarbons may
be inorganic:
Outer planets and moons contain methane.
Some stony meteorites (chondrites) contain hydrocarbons.
Carbonaceous chondrites (5% of all chondrites) are a type of stony
meteorites that contain Silicates, Oxides, Sulfides and traces of
various hydocarbons, including amino acids. Most chondrites
(86% of all meteorites) are rich in silicate minerals olivine and
pyroxenes. (Iron meteorites account for <6% of all meteorites but make up ~90% of
the mass of all known meteorites.)
Since hydrocarbons formed from inorganic reactions in the above
2 examples, some think hydrocarbons on earth may have formed
in a similar way.
Abiotic Oil?
Methane is present in volcanoes (1% - 15%). Abiotic oil from the
mantle that migrated upward, or volcanoes erupting through a
cover of sediments already containing some hydrocarbons?
Some laboratory experiments using a high-pressure and high
temperature apparatus have produced petroleum from solid iron
oxide (FeO), marble (CaCO3) and H2O –with no biotic compounds
or hydrocarbons originally present.
Could petroleum be produced abiotically? Yes, in
association with extraterrestrial and internal igneous
activity but it’s not commercial grade.
Could petroleum be produced from recycling various waste?
Yes….
• Thermal Conversion Process (TCP)
Changing of manure and/or animal & vegetable waste to crude
oil.
• Thermal Depolymerization (TDP)
Can change many carbon-based materials into crude oil and
methane, and is not limited to manure or vegetable waste. Web

How long will current conventional oil reserves last?
• Known and projected global oil reserves expected to be 80%
depleted in 42 – 93 yrs. At the rate of consumption in 2008,
OPEC’s reserves will last ~85 yrs.
• Known recoverable US reserves is ~21 billion barrels and US
consumes ~22 million barrels/day.
US reserves with no oil imported:
21 billion barrels/22 million barrels/day = 2.6 years
US imports ~13.5 million barrels of oil/day (~61% of 22 mill).
21 billion barrels/the remaining 8.5 million US barrels use/day = 6.7 years
•
Opening the Arctic National Wildlife Refuge to drilling would add ~4 – 10 months
• Saudi Arabia alone could supply world for ~10 yrs.
• Global oil consumption is expected to increase >30% by 2020.
