摘要： The improved recovery of hydrocarbons from subterranean formations by hydraulically fracturing a subterranean formation is accomplished. Fracturing fluids using a viscosifying surfactant fluid containing viscosifying micelles, for example, wormlike micelles, are useful to improve recovery of hydrocarbons and limit the loss of fracturing fluid into the formation fracture face. The invention further relates to novel fracturing and acidizing methods useful for increasing hydrocarbon production, limiting water production, resisting fracturing fluid loss into the subterranean formation, and reducing the equipment requirements in mixing and pumping fracturing fluid. The action of viscosifying micelles of surfactant in aqueous zones of the subterranean formation diverts fracturing fluid or acid from the aqueous zones to the hydrocarbon-bearing zones and also facilitates the flowback of increased amounts of hydrocarbons once a fractured well is placed back on production. These methods selectively block the pore structure in a water-bearing zone and do not blocking the pore structure of a hydrocarbon zone at the formation face. The step for selectively blocking forms a plug of a viscous fluid containing viscosifying micelles in the pore structure of the water-bearing zone at the formation face.

摘要： Prior to pumping completion brine fluid into a wellbore, an additive comprising two percent (2%) of a 0.25% solution of polyacrylamide is blended into the completion brine fluid thereby producing a treated brine fluid. This blending would be performed in tanks at the wellsite. The treated brine fluid is then pumed into the wellbore. In addition, or in the alternative, a new perforating gun stores the polyacrylamide additive composition. When the perforating gun detonates, the additive is disbursed into the completion brine fluid disposed in the annulus of the wellbore. For example, the new perforating gun may include a plurality of shaped charges coated with a lacquer of the polyacrylamide additive, or it may include one or more containers which contain the polyacrylamide additive. When the brine completion fluid is pumped into the wellbore annulus, a detonation wave conducts in a detonating cord of the perforating gun. The detonation wave passes through each of the containers. As a result, the containers will rupture and the plurality of shaped charges will detonate. Since the containers each ruptured, the polyacrylamide additive composition from the containers will be disbursed into the brine completion fluid in the annulus. In addition, or in the alternative, since the shaped charges of the new perforating gun were coated with a lacquer of the polyacrylamide composition, when the shaped charges detonated, the polyacrylamide composition on the zinc charge debris mixes with the brine fluid in the wellbore annulus. Zinc oxychloride hydrate debris is formed as a reaction product. However, the presence of the polyacrylamide additive in the zinc oxychloride hydrate debris will inhibit the formation of hardened chunks of a cement-like material in the annulus of the wellbore.

摘要： A novel method and device for manipulating ferrofluids for use in cementing wells are disclosed. The cementitious fluids may comprise: (a) a hydraulic cement, (b) finely divided magnetic particles, (c) a binding agent or a surfactant, and (d) a liquid medium. The binding agent or surfactant is present in the compositions in an amount sufficient to render the compositions stable in a magnetic field. When used in cementing wells, the cementitious ferrofluids are implaced in the annulus separating a casing from the formation in a wellbore by conventional techniques and the slurry is subsequently subjected to an activating alternating magnetic field that causes movement of the flurry. The non-cementitious ferrofluids comprise: (a) finely divided magnetic particles, (b) stabilizing agent, and (c) a liquid medium. The movement of the slurry results in a "scrubbing" action against the surface of the casing and formation surfaces, and a mixing of the slurry which helps displace any residual drilling mud. The net result is better bonding of the cement to the casing and formation.

摘要： The crosslinking of galactomannan gum fracturing fluids by borate ion is delayed for high-temperature applications by encapsulating the boron with a polymer coating. The crosslink-delay time is further adjusted by varying the concentration of an organic polyol. The polyol also acts as a stabilizer for the crosslinked fluid at elevated temperatures. Low pumping friction pressures are achieved by the delay in the crosslinking with the boron available at high temperatures to add high-temperature stability to the fracturing fluid at temperatures ranging up to about 350.degree. F.

摘要： Viscoelastic surfactant based aqueous fluid systems are described that are useful in fracturing subterranean formations penetrated by a wellbore. The preferred thickening agents are quaternary ammonium halide salts derived from certain waxes, fats and oils. The thickening agent is used in conjunction with an inorganic water soluble salt such as ammonium chloride or potassium chloride, and an organic stabilizing additive selected from the group of organic salts such as sodium salicylate. The resulting fluids are stable to a fluid temperature of about 225.degree. F.
