Abstract

Disclosed herein is a wellbore servicing fluid including an aqueous fluid, an oil, and a compound according to Structure I or Structure II. The wellbore servicing fluid can be used as a drilling fluid in a method of servicing a wellbore penetrating a subterranean formation. The wellbore servicing fluid can have an increased emulsion stability, a reduced dilution and waste volume, and can reduce fluid loss and/or salt washout when drilling though certain subterranean formations such as salt domes.
