International Classification:
C09K 8/524 C11D 1/38 C11D 11/00 C11D 3/04
Abstract:
A method of treating a portion of a well comprising: forming a treatment fluid, wherein the treatment fluid comprises: (A) water; and (B) a surfactant, wherein the surfactant is environmentally-friendly, and wherein the surfactant causes a liquid hydrocarbon to become soluble in the treatment fluid; and introducing the treatment fluid into the well, wherein the treatment fluid comes in contact with wellbore particles after introduction into the well, wherein at least a portion of the wellbore particles are coated with the liquid hydrocarbon prior to contact with the treatment fluid.

International Classification:
C09K 8/68 C09K 8/90 C09K 8/88 C09K 8/60
Abstract:
A fracturing fluid and method of including a cellulose polymer derivative, a diol functional group, and a borate crosslinker. The diol functional group may be a cis-diol functional group, a 1,2-diol functional group, or a 1,3-diol functional group. The cellulose polymer derivative further may include a hydroxyethyl group or a hydroxypropyl group. The fracturing fluid may also include at least one metallic crosslinker. The method may also include the steps of adding a pH adjusting agent, at least one breaker, a surfactant, a scale inhibitor, and/or a bactericide to the fracturing fluid, or mixing the fracturing fluid using mixing equipment or wherein the fracturing fluid is introduced into a subterranean formation using one or more pumps.
