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 ΔN1(F) to ΔN1(P) so that ΔN1(F)≧ΔN1(P), wherein ΔN1(F)=|N1(A)|−|N1(B)|.
