Context: water displacing oil.
Water drive a very effective recovery mechanism.
Water injection a very common oilfield practise.
Modelling water drive is often carried out within reservoir simulators.
Objective: to understand the mechanisms rather than blindly using the ‘black box’.
Useful texts;...

The various drive mechanisms come from the impact of a number of phenomena:
Expansion of reservoir fluids, oil, gas & water
Liberation, expansion of solution gas
Expansion of reservoir rock and reduction of pore volume.
Gravity forces.

New York: Simon & Schuster, 1990. — 912 p.
The Prize: The Epic Quest for Oil, Money, and Power is Daniel Yergin's history of the global petroleum industry from the 1850s through 1990. The Prize became a bestseller, helped by its release date in December 1990, four months after the invasion of Kuwait ordered by Saddam Hussein and one month before the U.S.-led coalition began the...
