Abstract
Methods including providing a silane composition selected from the group consisting of a dipodal silane, a long-chain silane, and any combination thereof, wherein the dipodal silane includes at least two carbon chains having between about 2 and about 36 carbon atoms, and wherein the long-chain silane includes at least one carbon chain having between about 2 and about 36 carbon atoms; coating proppant particulates with the silane composition, thereby forming silane composition coated proppant particulates; and introducing the silane composition coated proppant particulates into at least one fracture in a subterranean formation, thereby stabilizing loose particulates therein.
Claims16
A method comprising:
- providing a silane composition selected from the group consisting of a dipodal silane, a long-chain silane, and any combination thereof,
- wherein the dipodal silane includes at least two carbon chains having between 8 and 36 carbon atoms and is selected from the group consisting of:
- and any combination thereof,
- wherein p and r are integers between 1 and 30;
- wherein m and n are carbon chains having between 8 and 36 carbon atoms;
- and wherein R1 through R4 are carbon chains having between 1 and 4 carbon atoms, including bis- and tris-species thereof, and
- wherein the long-chain silane includes at least one carbon chain having between 8 and 36 carbon atoms and is represented by the Formula:
- wherein m and n are carbon chains having between 8 and 36 carbon atoms, and R5 through R8 are carbon chains having between 1 and 4 carbon atoms, including bis- and tris-species thereof;
- coating proppant particulates with the silane composition, thereby forming silane composition coated proppant particulates;
- and
- introducing the silane composition coated proppant particulates into at least one fracture in a subterranean formation, thereby stabilizing any loose particulates therein.
