  • Publication number: 20120316088
    Abstract: A method for determining a Plug Normal Stress Difference (?N1(P)) may include providing a test base drilling fluid that is characterized by N1(TB); adding a first concentration of a test particulate to the test base drilling fluid; adjusting the concentration of the test particulate in the test base drilling fluid to achieve a minimum concentration of the test particulate in the test base drilling fluid that will substantially plug a tapered slot, wherein the test base drilling fluid with the minimum concentration of the test particulate is characterized by N1(TA); and calculating ?N1(P)=|N1(TA)|?|N1(TB)| wherein each First Normal Stress Difference is measured by the same procedure.

  • Publication number: 20120316089
    Abstract: A drilling fluid may include a base drilling fluid and a plurality of particulates, wherein a concentration of the particulates in the base drilling fluid provides for ?N1(F)??N1(P), wherein ?N1(F)=|N1(A)|?|N1(B)|. The particulates may be lost circulation materials including, for example, fibers.

  • 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.

  • 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)|.
