摘要： A treatment fluid composition for treating a subterranean formation penetrated by a wellbore is formed from an aqueous fluid, a hydratable polymer and a water-soluble, non-symmetrical, inorganic peroxide breaking agent, which is capable of undergoing heterolytical cleavage. A method of treating a subterranean formation penetrated by a wellbore may also be performed by forming a treatment fluid from an aqueous hydrated polymer solution. This is combined with a water-soluble, non-symmetrical, heterolytically cleavable inorganic peroxide breaking agent. The treating fluid is introduced into the formation. An optional crosslinking agent capable of crosslinking the polymer may also be included.

摘要： Methods for treating a formation penetrated by a wellbore which improves fluid loss control during treatment. In some aspects, the treatments include preparing an aqueous fluid including one or more water inert degradable polymers and an optional viscosifier, injecting the aqueous fluid into the wellbore at a pressure equal to or greater than the formation's fracture initiation pressure, and thereafter injecting into the wellbore a proppant laden fluid at a pressure equal to or greater than the formation's fracture initiation pressure. The water inert degradable polymer may be a polymer such as an emulsion polymer or a latex polymer. Some methods of the invention use a fluid which may have a normalized leak off coefficient (Cw/sqrt(K)) equal to or less than about 0.0022, 0.0014, or 0.0010. A conventional fluid loss additive may or may not be used in conjunction with the treatment fluid and/or the proppant laden fluid. The water inert degradable polymer may or may not substantially enter formation pores. In another aspect, methods for reducing matrix damage to a formation during a treatment operation include preparing an aqueous treatment fluid formed of at least one water inert degradable polymer, and injecting the fluid at a pressure equal or greater than the formation's fracture initiation pressure.

摘要： A method for selectively reducing the permeability of the higher permeability zones of a subterranean reservoir having heterogeneous permeability, such permeability reduction extending continuously from nearby the well as far into the reservoir as is desired. There is injected into the reservoir an aqueous solution or solutions of a water-soluble polymer, a material capable under certain conditions of at least partially cross-linking the polymer to form a gelatinous precipitate, a water-soluble alkaline material in an amount sufficient to maintain the pH of the polymer-containing composition above the pH at which cross-linking occurs until the composition has passed a desired distance through the reservoir, and a temperature-activated water-soluble acidic material dissolved in the aqueous solution in an amount sufficient to lower the pH of the overall solution to the pH at which cross-linking occurs when said solution is subjected to an elevated temperature. A continuous gelatinous plug is formed which extends from the immediate vicinity of the well to a point as close to the well as about 20 feet, when it is desired to plug a feature of the strata which extends only a short distance therein, or as far into the well as is desired, for example up to 200 feet, when it is desired to plug an extensive zone of high permeability.

摘要： Process fluids comprising more than 1 wt % polyacrylamide and a non-metallic crosslinker may be used to control lost circulation in subterranean wells. The process fluid is placed into a subterranean lost-circulation zone and allowed to crosslink, thereby forming a gel barrier that limits further flow of process fluid into the zone. The non-metallic crosslinker may preferably comprise one or more polylactams. A pH-adjusting agent may also be incorporated into the process fluid.
