Abstract:
A method of servicing a wellbore in contact with a subterranean formation, comprising placing a wellbore servicing fluid comprising a drilling fluid and lost circulation material into a lost circulation zone within the wellbore, wherein the lost circulation material comprises a polyelectrolyte multilayer material and a first counterion. A wellbore servicing fluid comprising a drilling fluid and a lost circulation material comprising a polyelectrolyte multilayer material and a counterion comprising a halide, wherein the LCM has a first state that is hydrophilic. A tunable lost circulation material comprising a base material, a polyelectrolyte multilayer on said base material, wherein the polyelectrolyte multilayer comprises a first electrolyte layer, a second electrolyte layer, and a charged surface, and a counterion, wherein wettability of the lost circulation material is a function of the counterion.
