  • Patent number: 4615393
    Abstract: A process for fracturing a subterranean formation surrounding a gas or oil well which comprises injecting into said subterranean formation under hydraulic pressure a fluid comprising about 0.01 to about 25 weight percent of a water insoluble polymer complex dissolved in a solvent system of a nonpolar organic liquid, said polymer complex comprising the interaction product of a metal neutralized sulfonated polymer and an amine containing polymer, wherein the sulfonate content of the sulfonated polymer is about 4 meq. per 100 gram of polymer to about 200 meq. per 100 gram of polymer and the basic nitrogen content of the amine containing polymer is about 4 meq. per 100 gram of polymer to about 500 meq. per 100 gram of polymer.

  • Patent number: 4579671
    Abstract: A process for fracturing a subterranean formation surrounding a gas or oil well which comprises injecting said subterranean formation under hydraulic pressure with a fluid comprising about 0.1 to about 75 percent of an interpolymer complex dissolved in a solvent system of a nonpolar organic liquid and a polar cosolvent (as desired), said polymer complex comprises the interaction product of a sulfonated polymer and an amine containing polymer, wherein the sulfonate content of the sulfonated polymer is about 4 meq. per 100 gram of polymer to about 200 meq. per 100 gram of polymer and the basic nitrogen content of the amine containing polymer is about 4 meq. per 100 gram of polymer to about 500 meq. per 100 gram of polymer, and by the addition of polar cosolvent to such solution of polymer complex modifying its rheological properties over a wide range and their subsequent use as fracturing fluids.

  • Patent number: 4480693
    Abstract: The present invention relates to materials which reduce the filtration of fluid into permeable earth formations during cementing processes in the drilling and completing of subterranean wells, particularly wells for the recovery of petroleum resources.Petroleum well cementing is the process of mixing a slurry of cement, water, and other additives and pumping it down through steel casing to critical points in the oil well annulus around the casing or in the open hole below the casing string. The primary functions of the cementing process are to restrict fluid movement between geological formations and to bond and support the casing. In addition the cement aids in protecting the casing from corrosion, preventing blowouts by quickly sealing formations, protecting the casing from shock loads in drilling deeper wells, and sealing off lost circulation or thief zones.A common problem in petroleum well cementing is the flow of liquid from the cement slurry into porous earth formations in contact with the cement.
