Abstract: A method and system for corrosion control and scale control in water supply for injection, including specifying a corrosion inhibitor for squeeze treatment of a water supply well, specifying a scale inhibitor that can form a complex with the corrosion inhibitor, pumping the corrosion inhibitor and the scale inhibitor through a wellbore of the water supply well into an aquifer in a subterranean formation, forming the complex of the corrosion inhibitor and the scale inhibitor, and pumping water from the water supply well to an injection well for injection, the water including the scale inhibitor released from the complex in the aquifer and the corrosion inhibitor released from the complex in the aquifer.

Abstract: Gas hydrate inhibiting compositions include random polymers prepared from polyacrylates. The random polymers include at least one acrylate ester monomer in combination with at least one amine functional monomer. Methods for synthesizing the gas hydrate inhibiting polymers include polymerization of an acrylate then post-modifying a polyacrylate with an amine from at least one amine compound. Methods for inhibiting formation of clathrate hydrates in a natural gas pipeline include adding the gas hydrate inhibiting polymers to a natural gas pipeline.
