Abstract
Silyl-modified polyamides, and subterranean formation treatments employing silyl-modified polyamides to minimize migration or movement of naturally occurring or introducable solid particulates within a subterranean formation and/or within a wellbore penetrating a subterranean formation.
Claims27
A well treatment method, comprising introducing a well treatment fluid into a wellbore penetrating a subterranean formation, said well treatment fluid comprising a silyl-modified polyamide compound.
A well treatment method, comprising:
- introducing a well treatment fluid into a wellbore penetrating a subterranean formation, said well treatment fluid comprising a silyl-modified polyamide compound that is a reaction product of a polyamide compound and a silating compound;
- and
- contacting at least one of introducable or naturally occurring particulates present in at least one of said wellbore or said subterranean formation with said well treatment fluid;
- wherein said well treatment fluid comprises introducable particulate material suspended within said well treatment fluid, said introducable particulate material being at least partially coated with said silyl-modified polyamide in an amount effective to reduce or substantially prevent movement of at least a portion of the individual particles of said introducable particulate material when said particulates are subjected to fluid flow within said wellbore or subterranean formation;
- wherein said silyl-modified polyamide is present in said well treatment fluid in an amount effective to at least partially coat and adhere to said introducable or naturally occurring particulates and to reduce or substantially prevent movement of at least a portion of said introducable or naturally occurring particulates contacted by said well treatment fluid when said particulates are subjected to fluid flow within said wellbore or subterranean formation;
- or a combination thereof.
