Compositions for and methods of stabilizing subterranean formations containing clays |
摘要 |
A composition of matter for use in stablizing shale formations in earth boreholes comprising polymeric products, e.g., polymers of a dialkyl aminoalkyl methacrylate, which can optionally be quaternized with an alkyl halide to produce drilling fluid additives which stablize borehole formations containing reactive clays in the presence of an aqueous medium. |
