Abstract
A method or process for hydraulically fracturing an underground hydrocarbon deposit includes using as a source of water an underground aquifer which contains water which is stable and clear in the aquifer but which may include undesirable chemical compounds as soluble components that are not in solution when subjected to reduced pressure at atmospheric conditions. Water from the aquifer is used as a source of water for the hydrocarbon fracturing process. The water is pumped at a pressure above its bubble point pressure A source well and a disposal well are drilled into the aquifer. A pump capable of maintaining the water above its bubble point pressure is provided, and a closed loop is established with a manifold, or a manifold and pumps, to keep the aquifer water circulating at a pressure above its bubble point pressure. The hydrocarbon reserve is fractured using the water.
