摘要： A viscoelastic gelled oil, for example gelled diesel or paraffin oil, is made with a gelling agent, for example a phosphate ester, a metal carboxylate, for example an aluminum carboxylate, and a gel-enhancing surfactant, for example a zwitterionic surfactant, for example erucylamidopropyl betaine. The gel-enhancing surfactant makes the gel viscoelastic, increases the stability and decreases the sensitivity to the concentrations of the gelling agent and the metal carboxylate. The enhanced viscoelastic gelled oils are used, as examples, in hydraulic fracturing, frac packing, gravel packing, diversion, fluid loss control, lost circulation control, sand control, wellbore cleanout, wellbore or pipeline sweeping, organic scale dissolution, organic scale removal, and drilling.

摘要： A method for increasing the rate of shear rehealing of fluids made with cationic, zwitterionic, and amphoteric viscoelastic surfactant fluid systems by adding an effective amount of a polymeric rheology enhancer selected from polypropylene glycols and block copolymers of polypropylene glycol and polyethylene glycol. For applications in which rapid shear rehealing is required, the rheology enhancer allows fluids to be made and used at lower viscoelastic surfactant concentrations. Preferred surfactants are betaines and quaternary amines. The fluids are useful in oilfield treatments, for example fracturing and gravel packing.

摘要： The invention provides a method for perforating a well with a perforating fluid comprising a viscoelastic surfactant that essentially stops fluid leak-off after perforation in an overbalanced condition. Another aspect of the invention provides the perforating fluid in itself. The well has a wellbore defined by a generally cylindrical casing in at least a portion of the wellbore (i.e., the wellbore is cased, although it is not necessary cased in its entire length). The wellbore passes through a subterranean formation that comprises hydrocarbon formation fluids (such as oil and/or gas), at least in certain strata. The method comprises placing a perforating device in a wellbore which includes at least one explosive perforating charge that can be detonated in order to perforate the casing and allow the formation fluids to enter the wellbore. The casing is located between the subterranean formation and the perforating device. A perforating fluid including at least one viscoelastic surfactant is placed in the wellbore between the perforating device and the casing, in at least a portion of the wellbore. In other words, the perforating fluid is present in the wellbore adjacent to the perforating device. The explosive charge(s) in the perforating device is detonated, such that the perforating device forms at least one perforation in the casing that permits the flow of hydrocarbon formation fluids from the subterranean formation into the wellbore. As a result of the detonation, at least a portion of the perforating fluid is put in communication with the subterranean formation.
