LSU PETE 1010 Exam 1: Introduction to Petroleum Engineering
manage technical aspects of drilling exploratory, production, and injection wells - correct answer
✔✔drilling engineers
evaluates the well to determine the ability of the borehole to produce petroleum - correct answer
✔✔Well Log Analysts (Petro-physicists)
includes subsurface engineers, manage the interface between the reservoir and the well including
perforations, sand control, downhole flow control, and downhole monitoring equipment; evaluate
artificial lift methods; and, also select surface equipment that separates the produced fluids (oil, natural
gas, and water) - correct answer ✔✔Production Engineers
work to optimize production of oil and gas via proper well placement, production rates, and enhanced oil
recovery techniques. - correct answer ✔✔Reservoir Engineers
Oil demand; the amount of oil the world uses in a given time period. - correct answer ✔✔comsumption
Oil Supply; the amount of oil the world produces in a given time period. - correct answer ✔✔production
the amount of oil in stock tanks that is not needed for current supply demand - correct answer
✔✔inventories
Oil from wells that are already drilled but not currently producing. If spare production capacity is high,
then there is most likely little incentive for engineers to drill new wells. - correct answer ✔✔Spare
Production Capacity
The price of oil or gas might increase or decrease because of tensions between countries. In addition,
investment in less stable countries carries a higher risk than does an investment in a stable country. -
correct answer ✔✔Geopolitical Risks
,examples of market variables - correct answer ✔✔Future market trading activities, commodity
investment, exchange rates, equity markes
porosity equation - correct answer ✔✔volume of pore space / bulk volume of rock formation
porosity between grains - correct answer ✔✔Inter-granular porosity
porosity within grains - correct answer ✔✔Intra-granular porosity
mineral crystals that have grown around the sediment grains & bonded them together. - correct answer
✔✔Cementation
the size of the sand grains do not affect porosity: however, the range of variations of sand grains affect
porosity. - correct answer ✔✔Packing
if sand grains within a reservoir are elongated or flat and are packed with their flat surfaces together
than porosity might be low compared to a reservoir with spherical shaped sand grains. - correct answer
✔✔Shape
arrangement in which grains were laid down and compacted, amount of clay or other material that
cements the sand grains together. - correct answer ✔✔Deposition
which three main factors affect porosity? - correct answer ✔✔packing, shape, deposition
A rock is _____ when its pores are connected, so that fluids can flow through it by moving from one pore
to another pore. - correct answer ✔✔permeable
The interconnected pore volume or void space in a rock that contributes to fluid flow or permeability in a
reservoir. Effective porosity excludes isolated pores and pore volume occupied by water adsorbed on clay
minerals or other grains. Total porosity is the total void space in the rock whether or not it contributes to
fluid flow. Effective porosity is typically less than total porosity. (Schlumberger) - correct answer
✔✔Effective Porosity
, the oldest theory which suggests that petroleum comes from the underneath part of the mantle very
long time ago before the existence of life on earth - correct answer ✔✔Abiogenesis-inorganic origin of
petroleum
Theory that suggests that petroleum is formed from biological matters, left behind by very ancient lives.
These matters become subjected to high temperature under the absence of oxygen. - correct answer
✔✔biotic or organic origin of petroleum
which hypothesis about the origin of petroleum is widely supported? - correct answer ✔✔biotic or
organic origin
As the earth existence is date back to 4.5 billion years, the _____ theory is said to occur in that time,
before the appearance of any form of life - correct answer ✔✔Abiotic
_____ origin of petroleum (Hydrocarbons) suggests that petroleum come from a long time decaying of
died organisms such as planktons, zooplankton ad other form of biological species under a subjection of
high temperature. - correct answer ✔✔Biogenetic
According to ______ hypothesis, very long time ago, the organisms (marine living things, terrestrial) died
and buried and covered by silt in a sedimentary basin where they undergo a very slow and very long
lasting physical and chemical transformation which involves processes such as diagenesis and kerogen
formation. - correct answer ✔✔biogenetic (organic)
the arguments of abiotic versus biotic origins of petroleum are caused by some hidden reasons which
are for particular interests and _____ motivated - correct answer ✔✔politically
The _____ theory holds that petroleum is either left over from the formation of the solar system or was
formed later deep within the earth when hydrogen and carbon came together, as a result of heat and
pressure on mineral. - correct answer ✔✔inorganic
Geologists who support the _____ theory also believe that the theory explains why petroleum taken
from a large area is often chemically similar even though the formations where it was found are made of
different types of rocks of different geological ages. - correct answer ✔✔inorganic
