A method for completing boreholes penetrating narrow gradient zones in a subterranean formation after drilling with an oil based drilling fluid for recovery of hydrocarbons. The method employs an epoxy-based resin composition with controllable density and rheology that provides a low equivalent circulating density and is compatible with the oil based drilling fluid. The composition acts as a substitute for cement in cementing operations including adhering casing to the borehole, zonal isolation, and consolidation. |
