SURFACE-MODIFYING AGENTS FOR WETTABILITY MODIFICATION

摘要

A method and composition for treating a subterranean formation with a fluid,including forming a fluid including aparticulate and an organosilane with the chemical formula RnSiX4-n, wherein nis equal to 1, 2, or 3, R is an organic functionalgroup, and X is a halogen, alkoxy, or acetoxy group, introducing the fluidinto a subterranean formation with exposed surfaces,and modifying the wettability of a surface of the particulate or subterraneanformation or both. A method and composition fortreating a subterranean formation with a fluid including forming a fluidcomprising a particulate and an organosilane, introducingthe fluid into a subterranean formation with exposed surfaces, and modifyingthe wettability of the proppant or surfaces or both,wherein the wettability modification degrades. A method and composition forproducing hydrocarbon from a subterranean formation,including providing a wellbore in a subterranean formation, forming a fluidincluding a particulate and an organosilane withthe chemical formula RnSiX4-n, wherein n is equal to 1, 2, or 3, R is anorganic functional group, and X is a halogen, alkoxy, oracetoxy group, introducing the fluid into the subterranean formation withexposed surfaces, modifying the wettability of a surfaceof the particulate or the subterranean formation or both, and producinghydrocarbon from the wellbore in the subterranean formation.
