Слайд 2The hydrocarbon fluids are under pressure because of their depth.

Depending on the original characteristics of hydrocarbon reservoirs, the type

of driving energy is different.

Слайд 3Types of reservoir energy:
Energy of compression of the water and

rock within the reservoir
Energy of compression of oil within the

reservoir
Energy of compression of gas within the reservoir
Energy of compression of waters contiguous to and in communication with the petroleum reservoir
Gravitational energy that causes the oil and gas to segregate within the reservoir

Слайд 41. Solution Gas Drive Reservoirs
Crude oil under high pressure

may contain large amounts of dissolved gas
Recoveries are low,

on the order of 10-15 % of the original oil in place (OOIP).
Usually good candidates fro water-flooding

Слайд 5Distribution of water, oil, and gas in a solution-gas-drive reservoir:

(a) before production and (b) during depletion.

Слайд 62.Water drive reservoir
Most oil or gas reservoirs have water aquifers.
The

pore spaces vacated by oil or gas produced are filled

by water.
Recovery efficiencies of 70 to 80 % of the original oil in place (OOIP) are possible in some water drive reservoirs.

Слайд 7 Distribution of water and oil and position of water/oil contact

(WOC) in a water drive reservoir (a) before production and

(b) during depletion.

Слайд 83. Gas-cap reservoir
In gas cap drive reservoirs, wells are drilled

into the crude oil producing layer of the formation.
As

oil production causes a reduction in pressure, the gas in gas cap expands and pushes oil into the well bores.

Слайд 9Distribution of water, oil, and gas and position of gas/oil

contact (GOC) in a segregating-gas-cap reservoir: (a) before production and

(b) during depletion.

Слайд 10Gravity drainage reservoir
Gravity drainage is a slow process because

gas must migrate up structure or to the top of

the formation to fill the space formerly occupied by oil. Gas migration is fast relative to oil drainage so those oil rates are controlled by the rate of oil drainage.
