recovery of the oil in Spraberry Trend, an oil field ranked third in the U.S. by total proven reserves, is so difficult that the area was dubbed "the world's largest unrecoverable oil reserve"?
Question 1: Petroleum engineering is the
discipline responsible for evaluating which well locations and
recovery mechanisms are appropriate for a reservoir and for
estimating recovery rates and ________ prior to actual
production.
Question 3: Also, some wells (secondary wells)
may be used to pump water, steam, ________ or various gas mixtures into the reservoir
to raise or maintain the reservoir pressure, and so maintain an
economic extraction rate.
Question 4: This form of recovery is used extensively to
increase oil production in the ________, which has very
heavy oil, yet accounts for 10% of the United States' oil
production.
Question 6: Occasionally, ________ (detergents) are injected to alter the surface
tension between the water and oil in the reservoir, mobilizing oil
which would otherwise remain in the reservoir as residual oil.
Question 7: In this type of
cogeneration plant, a gas turbine is used to generate ________ and the
waste heat is used to produce steam, which is then injected into
the reservoir.
Question 8: Historically, in the ________, some oil fields existed where
the oil rose naturally to the surface, but most of these fields
have long since been used up, except certain places in Alaska.
