In parts of Saudi Arabia and Iraq, for instance, porous rock allows oil to seep to the surface in small ponds. However, most oil is trapped in underground oil reservoirs. The total amount of petroleum in a reservoir is called oil-in-place. Many petroleum liquids that make up a reservoir's oil-in-place are unable to be extracted.

J Pet Technol 5 (01): 17–19. The compressibility of reservoir rock is a factor which is generallyneglected in reservoir engineering calculations.

The Reservoir Rock is the container of oil and gas underground, stor- age space being provided by the voids—pores—between the mineral grains, or by fractures in rocks of low porosity. All rocks are porous in varying proportions, but those with larger, interconnected pores, are the more efficient as reservoir rocks.

Pore volume compression coincided with extensive oil and water production and corresponding pressure reduction in producing formations. Pore spaces in reservoir rock are occupied by fluid phases, including oil, water, and gas phases. Darcy found that flow rate is proportional to the pressure change between the inlet and outlet of the porous medium.

The source rock must have been heated sufficiently to yield its petroleum. 3. There must be a reservoir to contain the expelled hydrocarbons. This reservoir must have porosity, to contain the oil and/or gas, and permeability, to permit fluid flow. 4.

The source rock is where oil is produced. It contains organic matters that are quickly covered by clays size sediments known as shale. When oil is "produced" in the source rock it moves to the reservoir rock (Sandstone) where it is kept up to maturity. Cap rock is responsible for preventing oil to escape from the source rock.

Petroleum reservoirs may contain any of the three fluid phases—water (brine), oil, or gas.

The forces that originally distribute the fluids are ...
