Wellbore drilling compositions

A drilling mud composition, comprising a solid-state lubricant, wherein the solid-state lubricant comprises:

• a first concentration of powdered latex;
• and
• a second concentration of sodium asphalt sulfonate (SAS), wherein the second concentration of SAS (by mass) is greater than or equal to the first concentration of latex (by mass),
• wherein the drilling mud composition comprises an oil-based carrier,
• wherein the first concentration of powdered latex is at least about 1 pounds per barrel (lbm/bbl) with respect to the drilling mud composition,
• wherein the powdered latex comprises at least one of a styrene butadiene copolymer or a vinyl acetate ethylene copolymer, and
• wherein the drilling mud composition has an average permeability plugging test (PPT) fluid loss at 300° F. with a 55 micrometer filtration disc of less than or about 1.06 mL when tested according to American Petroleum Institute (API) test 13B-2.
