  • Methods to Characterize Fracture Plugging Efficiency for Drilling Fluids
    Publication number: 20120264658
    Abstract: 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 ?N1(F) to ?N1(P) so that ?N1(F)??N1(P), wherein ?N1(F)=|N1(A)|?|N1(B)|.

  • Methods to Modify Drilling Fluids to Improve Lost Circulation Control
    Publication number: 20120264659
    Abstract: 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.
