In order to produce a commercially viable oil deposit,there must be a source rock,a reservoir rock,a seal rock,and a ____________.
A)large fracture connecting the reservoir rock to the surface of the Earth,so the oil can move freely toward the surface
B)filter rock-a rock of intermediate permeability located between the source and the reservoir rocks to remove impurities
C)heater rock-an intrusive igneous rock beneath the source rock to heat the oil and give it buoyancy
D)trap-a geologic configuration that forces oil to pool up and denies it passage to the surface

Question

The other options are incorrect. A large fracture connecting the reservoir rock to the surface is not necessary as oil can move through porous rock without a direct connection to the surface. There is no need for a filter rock as the oil can be refined and purified after extraction. A heater rock is not necessary as natural pressure and heat from the earth's interior are sufficient to heat the oil. However, a trap is necessary to prevent the oil from escaping to the surface and to keep it confined within the reservoir rock.
