LSU PETE 1010 EXAM 1 QUESTIONS WITH
ACCURATE ANSWERS
manage technical aspects of drilling exploratory, production, and injection wells
- ANSWER drilling engineers
evaluates the well to determine the ability of the borehole to produce petroleum
- 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) - ANSWER Production Engineers
work to optimize production of oil and gas via proper well placement, production
rates, and enhanced oil recovery techniques. - ANSWER Reservoir Engineers
Oil demand; the amount of oil the world uses in a given time period. - ANSWER
comsumption
Oil Supply; the amount of oil the world produces in a given time period. -
ANSWER production
the amount of oil in stock tanks that is not needed for current supply demand -
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. - 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. - ANSWER Geopolitical Risks
examples of market variables - ANSWER Future market trading activities,
commodity investment, exchange rates, equity markes
porosity equation - ANSWER volume of pore space / bulk volume of rock
formation
porosity between grains - ANSWER Inter-granular porosity
, porosity within grains - ANSWER Intra-granular porosity
mineral crystals that have grown around the sediment grains & bonded them
together. - ANSWER Cementation
the size of the sand grains do not affect porosity: however, the range of
variations of sand grains affect porosity. - 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. - ANSWER Shape
arrangement in which grains were laid down and compacted, amount of clay or
other material that cements the sand grains together. - ANSWER Deposition
which three main factors affect porosity? - 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. - 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) -
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 -
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. - ANSWER biotic or organic origin of
petroleum
which hypothesis about the origin of petroleum is widely supported? - 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 - ANSWER Abiotic
_____ origin of petroleum (Hydrocarbons) suggests that petroleum come from a
long time decaying of died organisms such as planktons, zooplankton ad other
