Claims32
A method for sand consolidation in a subterranean formation, the method comprising:
- combining 1) a) an aminosilane component and an epoxysilane component, b) an aminosilane component and a silane-free cross linking component having two or more linking groups, c) an epoxysilane component and a silane-free cross linking component, or d) an aminosilane component, an epoxysilane component, and a silane-free cross linking component, and 2) a hydrocarbon carrier, to form a composition comprising a multipodal product and the hydrocarbon carrier;
- and
- introducing the composition into a subterranean formation via a wellbore that is formed in the subterranean formation such that the composition bonds to a sand surface of sand in the subterranean formation.
A sand consolidation composition comprising:
- a multipodal product comprising a) an aminosilane component and an epoxysilane component, b) an aminosilane component and a silane-free cross linking component having two or more linking groups, c) an epoxysilane component and a silane-free cross linking component, or d) an aminosilane component, an epoxysilane component, and a silane-free cross linking component;
- and
- a hydrocarbon carrier.
A method for reducing water effective permeability in a subterranean formation, the method comprising:
- combining 1) a) an aminosilane component and an epoxysilane component, b) an aminosilane component comprising an aminosilane and an organosilane component comprising an organosilane having one or more head groups configured to crosslink with an amine group of the aminosilane, c) an epoxysilane component comprising an epoxysilane and an organosilane component comprising an organosilane having one or more head groups configured to crosslink with an epoxy group of the epoxysilane, d) an isocyanosilane component and an organosilane component having one or more head groups of a primary amine group, a secondary amine group, a primary alcohol group, a secondary alcohol group, a mercapto group, or a carboxylic acid group, or e) a mercaptosilane component and an organosilane component having one or more head groups of an isocyanate group or a vinyl group, and 2) a hydrocarbon carrier, to form a composition comprising a multipodal product and the hydrocarbon carrier;
- and
- introducing the composition into a subterranean formation via a wellbore that is formed in the subterranean formation such that the composition bonds to a pore surface in a pore of the subterranean formation.
A water block composition comprising:
- a multipodal product comprising a) an aminosilane component and an epoxysilane component, b) an aminosilane component comprising an aminosilane and an organosilane component comprising an organosilane having one or more head groups configured to crosslink with an amine group of the aminosilane, c) an epoxysilane component comprising an epoxysilane and an organosilane component comprising an organosilane having one or more head groups configured to crosslink with an epoxy group of the epoxysilane, d) an isocyanosilane component and an organosilane component having one or more head groups of a primary amine group, a secondary amine group, a primary alcohol group, a secondary alcohol group, a mercapto group, or a carboxylic acid group, or e) a mercaptosilane component and an organosilane component having one or more head groups of an isocyanate group or a vinyl group;
- and
- a hydrocarbon carrier.
