摘要： A method for in situ acid stimulation of a subterranean formation that contains a hydrocarbon reservoir may include contacting the formation with an acidizing fluid comprising an aqueous fluid, a sulfonyl chloride, and a mutual solvent, wherein upon exposure to formation temperatures, the sulfonyl chloride and aqueous fluid hydrolyze the sulfonyl chloride, thereby producing hydrochloric acid.

摘要： A liquid phase enhanced oil recovery system that, in a stimulation phase, pumps a liquid mixture of propane (C3) and butane (C4) having a starting ratio of C3 to C4 into a well. During a subsequent production phase, liquid C3 and liquid C4 is recovered by a stabilizer from the produced oil, and, in addition, C3 and C4 can be recovered from the produced hydrocarbon vapor and liquefied, The ratio of liquid C3 to liquid C4 can then be re-adjusted and may not be the same as the starting ratio. All of the liquid C3-C4 can be recycled back into the well in subsequent stimulation phases. The method works at relatively low pressures, so that a pump or pumps can be used for stimulation treatment. The site equipment is compact enough that it can be mounted on one or more skids to ensure transportability to be used on other wells.

摘要： A fracturing fluid including a mixture of an aqueous terpolymer composition including a terpolymer, an additive, and crosslinker. The terpolymer includes 2-acrylamido-2-methylpropanesulfonic acid, acrylamide, and acrylic acid monomer units, or a salt thereof. The additive includes a sugar alcohol or a derivative thereof, and the crosslinker includes a metal. The weight ratio of the metal to the terpolymer is in a range of 0.01 to 0.16, and a concentration of the additive is in a range of 0.001 wt.% to 10 wt.% of the fracturing fluid. Treating a subterranean formation includes introducing the fracturing fluid into a subterranean formation, and crosslinking the fracturing fluid in the subterranean formation to yield a crosslinked fracturing fluid. The crosslinked fracturing fluid mitigates damage caused by substantial amounts of total dissolved solids or significant water hardness.

摘要： The present disclosure provides a bulk treatment for introduction into a hydrocarbon bearing formation, the bulk treatment comprising a volume of a treatment fluid comprising chlorine dioxide, wherein the volume is such that when the treatment fluid is introduced into a wellbore that penetrates the hydrocarbon bearing formation, the fluid is expected to extend into the formation to a radius that goes beyond the near wellbore region. Such a bulk treatment can act to draw out hydrocarbons from a hydrocarbon-bearing formation, thereby enhancing recovery of oil and/or gas. Also provided herein are mixtures comprising chlorine dioxide, water, an organic non-polar solvent, and optionally one or more additional components (e.g., an acid or chelating agent and/or a surfactant or cosolvent). The mixtures are useful for enhancing recovery of oil and/or gas and for removing residues that contain hydrocarbons. Apparatus for making the mixtures, and methods of making and using the mixtures, e.g., to mitigate damage and/or enhance recovery of oil and/or gas from a petroleum well, are also disclosed.

摘要： A breaker composition for use in a fracturing fluid comprises at least one organic peroxide (e.g., tert-butyl hydroperoxide), at least one dye (e.g., an FD&C dye), and at least one alcohol (e.g., propylene glycol). A promoter composition for use in a fracturing fluid comprises at least one promoter (e.g., sodium thiosulfate), at least one dye (e.g., an FD&C dye). According to certain embodiments, the dye increases the efficiency of the promoter and/or the organic peroxide, so that the break time and the peak viscosity of the aqueous treatment fluid are reduced.
