Abstract
Increasing the dispersed phase concentration in drilling fluids may decrease sag in the drilling fluids. The dispersed phase of a drilling fluid may be composed of solids (e.g., weighting agents) and emulsion droplets (for emulsified drilling fluids) dispersed in the continuous phase. For example, an exemplary drilling fluid may include a base fluid and a dispersed phase that includes at least one of: extremely low gravity solids, low gravity solids, high gravity solids, or emulsion droplets; wherein the drilling fluid has a density of about 5 pounds per gallon to about 25 pounds per gallon and has a disperse solids volume fraction greater than or equal to 0.35 and/or has a disperse phase volume fraction greater than or equal to 0.5.
