A method of servicing a wellbore in contact with a subterranean formation
comprising placing in the wellbore a composition comprising a metal
oxide, a soluble salt, a surfactant and an oleaginous fluid, and allowing
the composition to set. A method of cementing a wellbore comprising
placing a first composition comprising magnesium oxide, a chloride or
phosphate salt, an organophilic surfactant and an oleaginous fluid into a
wellbore, allowing the composition to set, placing a second cementitious
composition into the wellbore, and allowing the second cementitious
composition to set. A method of servicing a wellbore comprising placing
in the wellbore a composition comprising magnesium oxide, magnesium
chloride, an organophilic surfactant, water and an oleaginous fluid
wherein the organophilic surfactant is present in an amount of from about
0.25% to about 5% base on the combined weight of the magnesium oxide and
magnesium chloride, and the oleaginous fluid is present in a ratio of
from about 95:5 cement:oleaginous fluid to about 50:50 cement:oleaginous
fluid.
