Abstract
A method of treating a subterranean formation comprising: introducing a first treatment fluid into a well, wherein the first treatment fluid comprises a base fluid and a scale inhibitor; and introducing a second treatment fluid into the well, wherein the second treatment fluid comprises a base fluid and a surface modification agent, wherein the surface modification agent is a hydrophobically modified polyamide. A method of fracturing a subterranean formation comprising: introducing a fracturing fluid into a well, wherein the introduction of the fracturing fluid creates or enhances a fracture in the subterranean formation, wherein the fracturing fluid comprises: a base fluid; proppant; a scale inhibitor; and the surface modification agent.
