EMULSION SYSTEM UTILIZING NITROGEN AND HEAT TO TREAT DEEP WATER BLOCKAGE

摘要

Some examples of an emulsion system for treating deep water blockage can be prepared by emulsifying a first aqueous phase in a first organic phase to prepare a first emulsion. A second aqueous phase can be emulsified in a second organic phase to prepare a second emulsion. The first emulsion and the second emulsion can be flowed into a subterranean formation. The first aqueous phase and the second aqueous phase, when mixed, can react to release nitrogen and heat.

1. A method comprising:
emulsifying a first aqueous phase comprising sodium nitrite and a first acid in a first organic phase to prepare a first emulsion; emulsifying a second aqueous phase comprising ammonium chloride in a second organic phase to prepare a second emulsion; and flowing the first emulsion and the second emulsion into a subterranean formation, wherein the first aqueous phase and the second aqueous phase, when mixed, react to release nitrogen and heat.
