ABSTRACT:
A system for injecting fluid into underground formations for various purposes including the secondary and tertiary recovery of oil or other hydrocarbons from underground formations, storage of fresh water in underground formations, recharging depleted or insufficient fresh water underground strata from rainfall run off or other sources of fresh water to provide fresh water supply during low rainfall periods or the like, disposal of brine or saline solutions into underground formations where such solutions will be purified by filtering through porous media and disposal of contaminated fluids resulting from industrial, chemical processes, and the like. The system includes a unique injector capable of gravity flow injection or pressure injection by use of a pump arrangement with the gravity flow of fluids such as water enabling turbines to be utilized in the flow path at a point having the necessary water head and pressure characteristics to rotate a generator for providing electrical energy to power certain components of the equipment or for use in any manner desired.
