Method for reducing sag in drilling, completion and workover fluids |
摘要 |
A method is disclosed for reducing sag in drilling and completion fluids and in workover fluids. The method employs a drilling fluid comprising a low molecular weight polyalkyl methacrylate with an average molecular weight ranging from about 40,000 to about 90,000. This additive does not result in significantly increased viscosity of the fluid.
