Abstract

Disclosed herein is a method comprising displacing a first oil-based fluid present in an open hole interval of a wellbore with a second fluid; and contacting the second fluid with an acidic indigenous formation fluid to produce a third fluid wherein the second fluid an aqueous fluid dispersed as a discontinuous phase within an oleaginous fluid, and an amine surfactant, wherein the amine surfactant is selected such that contacting the second fluid with indigenous fluid protonates at least a portion of the amine surfactant in the second fluid to produce the third fluid comprising an emulsion comprising the oleaginous fluid reversibly dispersed as a discontinuous phase within the aqueous fluid. A system for treating a subterranean well and a fluid are also disclosed.
