Which characteristic is absolutely necessary for a sedimentary rock to have potential as a possible reservoir rock for oil or gas?

Question

Quizplus · Accepted Answer

A high porosity is necessary for a sedimentary rock to be a possible reservoir rock for oil or gas because it means that there are spaces for the hydrocarbons to accumulate and be stored. Without high porosity, the rock cannot hold significant amounts of oil or gas. Clastic texture, chemical origin, and good stratification may be helpful but are not absolutely necessary for a sedimentary rock to be a potential reservoir rock.
