Summary:An invert oil-based mud (OBM) may include an oleaginous continuous phase, an aqueous internal phase, an emulsifier; and a rheology modifier. The rheology modifier may include one or more of the group consisting of epoxidized methyl oleate, epoxidized methyl linoleate, and epoxidized methyl α-linolenate. The invert OBM may contain the rheology modifier in an amount of the range of 0.1 to 5 wt. % (weight percent) relative to the total weight of the OBM.
