METHODS TO CHARACTERIZE FRACTURE PLUGGING EFFICIENCY FOR DRILLING FLUIDS

摘要

Of the many compositions and methods provided herein, one method includes providing a drilling fluid comprising a base drilling fluid and a plurality of particulates, wherein the base drilling fluid without the particulates is characterized by N1(B) and wherein the base drilling fluid with the particulates is characterized by N1(A); and adjusting a concentration of the particulates in the drilling fluid by comparing the value of .DELTA.N1(F) to .DELTA.N1(P) so that .DELTA.N1(F)>= .DELTA.N1(P), wherein .DELTA.N1(F) = |N1(A)| - |N1(B)|.
