Methods For Recovering Hydrocarbon Materials From Subterranean Formations

Abstract

A method for recovering hydrocarbon material from a subterranean formation includes introducing a treatment fluid into the subterranean formation. One treatment fluid includes at least one organometallic material having a metal or metalloid from Group III of the Periodic Table or a transition metal. An optional second fluid having an organophosphorous material can also be introduced. Another treatment fluid includes the reaction product of a transition metal compound and a silicon-containing material.
