Which of the following is NOT true about shale gas and shale oil?
A) They are mostly hosted by shale.
B) Oil and gas remain largely trapped in unconnected pores in the host rocks, until liberated by drilling.
C) Shale basins can cover huge areas of the U.S.
D) Shale oil and shale gas mostly accumulate in anticlines and similar types of traps.

Question

Quizplus · Accepted Answer

Shale oil and gas are primarily found in the fine-grained sedimentary rock known as shale, where they are trapped within the tiny pores of the rock. Unlike conventional oil and gas, which often accumulate in larger, more easily accessible reservoirs like anticlines due to the migration of hydrocarbons, shale oil and gas remain trapped within the shale formation itself. The extraction of these resources typically requires hydraulic fracturing (fracking) to release them from the rock matrix. Therefore, the statement that shale oil and gas mostly accumulate in anticlines and similar types of traps is not true, as their accumulation is within the shale rock itself, not in conventional traps.
