Abstract
A treatment fluid for treating a portion of a subterranean formation comprises: a base fluid, wherein the base fluid comprises a hydrocarbon liquid; and a gellant, wherein the gellant: is a polymer; and is activated at an activation temperature, wherein the thermal activation of the gellant causes the treatment fluid to become a gel. A method of treating a portion of a subterranean formation includes introducing the treatment fluid into the portion of the subterranean formation, wherein the subterranean formation is penetrated by a well, wherein at least a portion of the well has a bottomhole temperature greater than or equal to the activation temperature, and wherein the step of introducing comprises introducing the treatment fluid into the portion of the well.
