First Claim
Patent Images
1. A method of treating a siliceous or metal (M) oxide-containing subterranean formation penetrated by a well comprising:
- a) pumping into the formation a surface modifying treatment agent having a metallic anchor and a hydrophobic tail; and
b) binding the metal of the metallic anchor of the surface modifying treatment agent to the surface of the siliceous formation or the metal, M, of the metal (M) oxide-containing subterranean formation.

Abstract
A method of treating a subterranean formation comprises pumping into a well penetrating the formation a surface modifying treatment agent having a metallic anchor and at least one hydrophobic tail attached to the metal of the anchor. The surface modifying treatment agent is covalently bound to the surface of the subterranean formation through the metal of the anchor.

28. A method of treating a siliceous or metal oxide containing subterranean formation penetrated by a well comprising:
-
(a) pumping into the formation a surface modifying treatment agent comprising the product of a metal containing organic ligand and an organo-silicon containing hydrophobic material wherein the metal of the metal containing organic ligand is selected from the group consisting of a Group 3, 4, 5 or 6 metal and the organic ligand of the metal containing organic ligand is selected from the group consisting of alkoxides, halides, keto acids, amines and acrylates; (b) attaching the surface modifying treatment agent to the surface of the subterranean formation. - View Dependent Claims (29)

30. A method of treating a siliceous or metal (M) oxide-containing subterranean formation penetrated by a well comprising:
-
(a) pumping into the well a treatment fluid comprising a surface modifying treatment agent having a metallic anchor and a tail; and (b) binding the surface modifying treatment agent onto the surface of the subterranean formation by forming a monolayer or multi-layer assembly by self-alignment of the tail wherein prior to step (a) the amount of sites for the surface modifying treatment agent to bind onto the surface of the subterranean formation are increased by pre-treating the subterranean formation with a non-aqueous fluid. - View Dependent Claims (31, 32, 33, 34)
