摘要： A system includes a hydraulic fracturing fluid including a polymeric constituent and an additive having particles including poly-vinyl acetate in an amount sufficient to control fluid loss. The system includes a formation of interest having a downhole temperature, and the particles including poly-vinyl acetate have a size and/or shape such that the poly-vinyl acetate hydrolyses at the downhole temperature. The particles may have a size and/or shape such that the particles are deformable at the downhole temperature. The poly-vinyl acetate in the particles may be a part of the particle substrate, a coating on the particles, and/or the entire particle may be poly-vinyl acetate. The poly-vinyl acetate may be included in any portion of the hydraulic fracturing fluid, or only the portion of the hydraulic fracturing fluid that is not proppant laden.

摘要： A fluid loss control method uses a fluid loss control pill in a well in advance of a completion operation. An embodiment of the fluid loss control pill comprises polyester solids that are hydrolysable and can exhibit plastic deformation at formation conditions. An embodiment of the method comprises spotting the fluid loss control pill in the well adjacent to a formation to form a filtercake to inhibit fluid entry from the well into the formation, performing a completion operation comprising contacting the filtercake with overbalanced wellbore fluid, and degrading the filtercake wherein the polyester particles are hydrolyzed to remove formation damage.

摘要： The invention provides a method. The method injects into a wellbore, a fluid comprising at least one of an acrylamide polymer and an acrylamide copolymer, and at least one of an oxidizing agent and a radical initiator; and allows viscosity of the fluid to increase for a first period of time; and subsequently, allows viscosity of the fluid to decrease for a second period of time. In a further aspect the invention provides a fluid for use in a well within a subterranean formation penetrated by a wellbore. The fluid is in a first embodiment, made of an acrylamide polymer and/or copolymer and an oxidizing agent or radical initiator, wherein concentration of the oxidizing agent or radical initiator is such that the fluid increases its viscosity for a period of time and after said period of time decreases its viscosity. The fluid is in a second embodiment, made of an acrylamide polymer and/or copolymer and an oxidizing agent or radical initiator, wherein the oxidizing agent or radical initiator is such that the fluid increases its viscosity for a period of time and after said period of time decreases its viscosity.

摘要： During “fracking” operations, proppants are used to keep open the fissures that are created, and stimulation fluids are often injected into the subterranean hydrocarbon-bearing geological formations to assist in capturing released hydrocarbons. However, because fissure surfaces formed in subterranean hydrocarbon-bearing geological formations from fracking tend to be hydrophobic, both introduced stimulation fluids and the hydrocarbons from the subterranean hydrocarbon-bearing geological formations tend to adhere to the fissure surfaces. The addition of a gemini surfactant appears to reduce the hydrophobic nature of the geological structure's fissure surfaces, thereby wetting surfaces of indigenous rock and/or introduced proppant surfaces. The addition of the gemini surfactant results in an increase of the fluid flow through the subterranean hydrocarbon-bearing geological formations, thereby enhancing of recovery of hydrocarbons and introduced stimulation fluids.

摘要： Wellbore-cleaning compositions comprising microemulsions are useful during cementing operations. The microemulsion solvent may be selected from the group comprising methyl esters and ethoxylated alcohols. The microemulsion surfactants comprise a water-wetting surfactant, a cleaning surfactant, an emulsifying surfactant, a non-ionic surfactant and a non-ionic co-surfactant. The wellbore-cleaning compositions may be pumped alone, ahead of a conventional spacer fluid or scavenger slurry and behind a conventional spacer fluid or scavenger slurry. In addition, the wellbore-cleaning composition may be incorporated into a carrier fluid such as (but not limited to) a conventional spacer fluid or scavenger slurry. The resulting fluid mixture may be pumped as a spacer fluid.
