Title: METHODS FOR DELIVERING WATER REACTIVE CHEMICALS TO SUBTERRANEAN RESERVOIRS FOR ENHANCED CRUDE OIL RECOVERY
Abstract:
This invention relates to methods for delivering water reactive chemicals, such as alkali metal silicides, metal silicides, and mixtures thereof, to subterranean reservoirs in order to increase the amount of crude oil that can be extracted from an oil field. The invention uses non-reactive and partially reactive hydrocarbon fluids, particle coatings, and fluidic flow control to manage the delivery of the water reactive chemical. The invention also relates to methods using water reactive chemicals to improve recovery of subterranean hydrocarbon and bituminous material and deposits.
