Method of drilling a subterranean well using a fluid pressure transmission pill and an oil-based drilling fluid

摘要

Disclosed herein is a method of drilling a subterranean well using a fluid pressure transmission pill in conjunction with an oil-based drilling fluid. The method comprises: providing a fluid pressure transmission pill (FPTP) by mixing an oleagineous liquid, an organophilic clay, and a polar activator to form a gel; introducing the FPTP into a wellbore of the well while a first fluid is present in the wellbore; and introducing a second fluid into the wellbore while the first fluid and the FPTP are in the wellbore, wherein the FPTP isolates the first fluid from the second fluid.
