Abstract: The present invention generally relates to methods and friction-reducers for decreasing the friction of a fluid. More specifically, the method comprises contacting a friction-reducer to reduce the friction of a fluid flowing in a conduit. The friction-reducer comprises an emulsion polymer, comprising polyanion, polycation, and polynonionic monomers, and a highly concentrated salt solution.

Abstract: Methods for reducing fines migration in a porous subterranean reservoir. In certain aspects, the methods include introducing a composition including a water-soluble or dispersible branched polyhydroxyetheramine into the porous subterranean reservoir, maintaining a sufficient temperature in the porous subterranean reservoir for a period of time, adsorbing the composition onto a surface of the porous subterranean reservoir, and stabilizing at least a portion of the fines present in the porous subterranean reservoir. A treatment composition can be used and in certain aspects, the treatment composition can be a reaction product of bisphenol A, an ethanol amine, diethanol amine, and a monofunctionalized polyoxyalkyleneamine.

Abstract: A composition including crosslinked expandable polymeric microparticles capable of hydrolysis at or below neutral pH and a method of modifying the permeability to water of a subterranean formation by introducing such compositions into the subterranean formation. This disclosure further relates to compositions and methods for the recovery of hydrocarbon fluids from a subterranean reservoir or formation subjected to CO2 or CO2 Water Alternating Gas flooding at low pH and increases the mobilization and/or recovery rate of hydrocarbon fluids present in the subterranean formations.

Abstract: Methods for acid diversion in a hydrocarbon-containing subterranean formation are disclosed. The methods include injecting an acid diversion agent comprising a water-soluble or dispersible branched polyhydroxyetheramine and injecting an acidic solution into a well which is in contact with the hydrocarbon-containing subterranean formation. Preferably, the acid solution is diverted toward a zone of the formation that has a lower permeability to fluid than an adjacent zone. This process improves the permeability of the hydrocarbon-containing subterranean formation to hydrocarbons, while decreasing the permeability of the formation to water or brine.
