Abstract
In one embodiment, this invention presents a foaming additive that comprises at least one amidopropyl betaine having the formula: R—CONHCH2CH2CH2N+(CH3)2CH2COO− wherein R is a capryloyl, a capryl, an octyl, a decyl, a cococyl radical, or a mixture thereof. This foaming additive may be utilized in foamed treatment fluids, and those foamed treatment fluids may be utilized in fracturing and sand control treatments in subterranean operations. Associated methods also are presented herein.
Claims88
A method of treating a subterranean formation, the method comprising:
- providing a foamed treatment fluid comprising water, a gas, a gelling agent, and a foaming additive, the foaming additive comprising at least one amidopropyl betaine having the formula:
- R—CONHCH2CH2CH2N+(CH3)2CH2COO−
- wherein R is a capryloyl, a capryl, an octyl, a decyl, a cococyl radical or a mixture thereof;
- and
- introducing the foamed treatment fluid into a well bore penetrating the subterranean formation.
A method of fracturing a portion of a subterranean formation, the method comprising:
- providing a foamed treatment fluid comprising water, a gas, and a foaming additive, the foaming additive comprising at least one amidopropyl betaine having the formula:
- R—CONHCH2CH2CH2N+(CH3)2CH2COO−
- wherein R is a capryloyl, a capryl, an octyl, a decyl, a cococyl radical, or a mixture thereof;
- and
- introducing the foamed treatment fluid into a well bore that penetrates the subterranean formation at or above a pressure sufficient to create or enhance one or more fractures in a portion of the subterranean formation.
A method of providing some degree of sand control in a portion of a subterranean formation, the method comprising:
- providing a foamed treatment fluid comprising water, a gas, particulates, and a foaming additive, the foaming additive comprising at least one amidopropyl betaine having the formula:
- R—CONHCH2CH2CH2N+(CH3)2CH2COO−
- wherein R is a capryloyl, a capryl, an octyl, a decyl, a cococyl radical, or a mixture thereof;
- and
- introducing the foamed treatment fluid into a well bore that penetrates the subterranean formation such that the particulates form a gravel pack in or adjacent to a portion of the subterranean formation.
A method of foaming a fracturing fluid comprising the step of adding to the fracturing fluid a gas and a foaming additive, the foaming additive comprising at least one amidopropyl betaine having the formula:
- R—CONHCH2CH2CH2N+(CH3)2CH2COO−
- wherein R is a capryloyl, a capryl, an octyl, a decyl, a cococyl radical, or a mixture thereof.
A method of producing hydrocarbons from a subterranean formation, the method comprising:
- providing a foamed treatment fluid comprising water, a gas, and a foaming additive, the foaming additive comprising at least one amidopropyl betaine having the formula:
- R—CONHCH2CH2CH2N+(CH3)2CH2COO−
- wherein R is a capryloyl, a capryl, an octyl, a decyl, a cococyl radical or a mixture thereof
- introducing the foamed treatment fluid into a well bore penetrating the subterranean formation;
- and
- producing hydrocarbons from the subterranean formation.
A foamed treatment fluid comprising water, a gas, a gelling agent, and a foaming additive, the foaming additive comprising at least one amidopropyl betaine having the formula:
- R—CONHCH2CH2CH2N+(CH3)2CH2COO−
- wherein R is a capryloyl, a capryl, an octyl, a decyl, a cococyl radical, or a mixture thereof.
A foamed fracturing fluid comprising water, a gas, and a foaming additive, the foaming additive comprising at least one amidopropyl betaine having the formula:
- R—CONHCH2CH2CH2N+(CH3)2CH2COO−
- wherein R is a capryloyl, a capryl, an octyl, a decyl, a cococyl radical, or a mixture thereof.
