Stimulation by Defoaming Increases Thermal Oil Production

Abstract: Foamed oil emulsions can exhibit significant increases in apparent viscosity due to the entrainment of gas bubbles in the oil. Crude asphaltic components act as natural foaming and emulsifying agents. Their influence causes a large portion of the dissolved gas, which would otherwise be liberated as free gas, to remain entrapped in the water-in-oil emulsion as small bubbles. Such in-situ generation of foamy oil emulsions in the vicinity of the wellbore can have a profound effect on well productivity. … Show more

“…[2][3][4][5][6][7] The practice of cyclic steaming, however; can cause formation damage in the reservoir that can severely effect the performance of post cyclic steam production. This damage primarily involves, but is not limited to, the formation of stable in-situ emulsion, wettability alteration, fines mobilization, and increased viscosity.…”

“…This damage primarily involves, but is not limited to, the formation of stable in-situ emulsion, wettability alteration, fines mobilization, and increased viscosity. 1,[5][6][7][8][9][10][11] Several factors associated with cyclic steam operations can contribute to the creation of in-situ emulsion. These components; an energy source, immiscible fluids, formation fines, and oil wet surfaces, are all naturally present in most steamdrive reservoirs.…”

“…In addition, wettability alteration and emulsions were known to be exacerbated by steamflooding-an extensive practice throughout Coalinga. 10 After analyzing the producing environment in West Coalinga, the following forms of formation damage were considered most likely:…”

“…As reported by Juprasert and Davis, 5 the best approach to overcome this problem is by disrupting the foam either chemically or hydraulically or both. The defoamer is a chemical additive that is widely used to disrupt the surface of the bubbles and break the existing foams.…”
