Abstract:
Accretion inhibiting wellbore fluid compositions a ay contain a multiester, a sorbitan ester surfactant, and a base fluid, wherein the composition is in the form of a metastable emulsion. Methods may include emplacing a wellbore fluid into a wellbore, the wellbore fluid containing a multiester, and a sorbitan ester surfactant, wherein the wellbore fluid forms a metastable emulsion.
