Abstract

Various embodiments disclosed relate to compositions including polyether-functionalized linear polysiloxanes and methods and systems for using the same to treat subterranean formations. In various embodiments, the present invention provides a method of treating a subterranean formation including obtaining or providing a composition including a polyetherfunctionalized linear polysiloxane. The method also includes placing the composition in a subterranean formation.

First claim

1 - 81 . (canceled)

82 . A method of treating a subterranean formation, the method comprising:
obtaining or providing a composition comprising a polyether-functionalized linear polysiloxane; and placing the composition in a subterranean formation.

83 . The method of claim 82 , wherein the polyether-functionalized polysiloxane is at least one of a surface modifier, an interface modifier, a defoamer, an antifoamer, a de-aerator, a demulsifier, a friction reducer, a flow enhancer, a surface protector, a solubilizer, a softener, and a corrosion inhibitor.

84 . The method of claim 82 , wherein about 0.01 wt % to about 99 wt % of the composition is water.

85 . The method of claim 82 , wherein the method further comprises mixing water with the polyether-functionalized polysiloxane.

86 . The method of claim 82 , wherein about 0.000,1 wt % to about 100 wt % of the composition is the polyether-functionalized polysiloxane.

87 . The method of claim 82 , wherein the polyether-functionalized polysiloxane has the structure:

wherein,
at each occurrence R 1 is independently selected from a substituted or unsubstituted (C 1 -C 20 )hydrocarbyl,
at each occurrence R 2 is independently selected from the group consisting of —R 1 and -L 1 -PE-R 3 ,
at each occurrence L 1 is independently selected from the group consisting of a bond and a substituted or unsubstituted (C 1 -C 20 )alkylene,
at each occurrence PE is independently selected from —(O—R 4 ) n —O—,
at each occurrence R 3 is independently selected from the group consisting of —H and a substituted or unsubstituted (C 2 -C 20 )alkylene,
at each occurrence R 4 is independently substituted or unsubstituted (C 2 -C 20 )alkylene,
n is about 1 to about 10,000, x is about 0 to about 100,000, y is about 0 to about 100,000, and x+y is at least 1, and
the polyether-functionalized polysiloxane comprises at least one polyether.

88 . The method of claim 87 , wherein at each occurrence R 4 is ethylene.

89 . The method of claim 87 , wherein at each occurrence R 3 is independently selected from the group consisting of —H, methyl, and ethyl.

90 . The method of claim 87 , wherein the polyether-functionalized polysiloxane has the structure:

91 . The method of claim 87 , wherein the polyether-functionalized polysiloxane has the structure:

92 . The method of claim 87 , wherein the polyether-functionalized polysiloxane has the structure:

93 . The method of claim 87 , wherein the polyether-functionalized polysiloxane has the structure:

94 . The method of claim 87 , wherein the polyether-functionalized polysiloxane has the structure:

95 . The method of claim 87 , wherein the polyether-functionalized polysiloxane has the structure:

96 . The method of claim 87 , wherein the polyether-functionalized polysiloxane has the structure:

97 . The method of claim 82 , wherein the composition further comprises a viscosifier.

98 . The method of claim 82 , wherein the composition further comprises a crosslinker.

99 . The method of claim 82 , wherein the composition further comprises a breaker.

100 . A method of treating a subterranean formation, the method comprising:
obtaining or providing a composition comprising
a polyether-functionalized linear polysiloxane having the structure

wherein,
at each occurrence R 1 is independently selected from a (C 1 -C 5 )alkyl,
at each occurrence R 2 is independently selected from the group consisting of —R 1 and -L 1 -PE-R 3 ,
at each occurrence L 1 is independently selected from the group consisting of a bond and a (C 1 -C 5 )alkylene,
at each occurrence PE is independently selected from —(O—R 4 ) n —O—,
at each occurrence R 3 is independently selected from the group consisting of —H, methyl, and ethyl,
at each occurrence R 4 is independently substituted or unsubstituted (C 2 -C 5 )alkylene,
n is about 1 to about 10,000, x is about 0 to about 100,000, y is about 0 to about 100,000, and x+y is at least 1, and
the polyether-functionalized polysiloxane comprises at least one polyether; and

at least one of a fracturing fluid or a drilling fluid, wherein about 0.000,1 wt % to about 10 wt % of the composition is the polyether-functionalized polysiloxane; and

placing the composition in a subterranean formation.

101 . A system comprising:
a composition comprising a polyether-functionalized linear polysiloxane; and a subterranean formation comprising the composition therein.
