Abstract:
A method of introducing treatment chemicals and treating a subterranean formation comprising the steps of:introducing a particulate-containing fluid suspension into a subterranean formation;admixing with at least a portion of said particulate in said fluid suspension a liquid or solution of a non-hardening tackifying compound whereby at least a portion of said particulate is at least partially coated by said compound;admixing with at least a portion of said particulate in said fluid suspension a treatment chemical whereby at least a portion of said treatment chemical is contacted by said tackifying compound and at least partially coated therewith whereby the tackifying compound retards release of said treatment chemical in said fluid suspension; anddepositing the tackifying compound coated particulates and treatment chemical in the subterranean formation whereby upon flowing back fluid from the formation the tackifying compound coated treatment chemical is subsequently released within the subterranean formation to treat at least a portion of the formation or fluids in contact therewith.
