Fremgangsmåder til at modificering af borefluider for at forbedre styring af cirkulationstab

摘要

Of the many compositions and methods provided here, one method includes providing a drilling fluid comprising a lost circulation material and a base drilling fluid, wherein the base drilling fluid comprises an oleaginous continuous phase and a polar organic molecule, wherein the base drilling fluid has a first normal stress difference magnitude (|N1|) greater than about 100 Pa; and drilling a portion of a wellbore in a subterranean formation using the drilling fluid.
