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
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 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.
