5604185 Inhibition of scale from oil well brines utilizing a slow release composition and a preflush and February 18, 1997
An improvement in a method for the inhibition of scale deposition on the surfaces of a well coproducing oil and scale forming brines, said method comprising injecting into the well reservoir an acidic aqueous solution at a first pH containing dissolved therein a scale inhibitor, multival
5377758 Method for effective placement of a long life scale inhibitor January 3, 1995
A method for placement of a long life scale inhibitor into a formation where variable density scale inhibitors are utilized. A substantially low density non-reactive fluid is loaded into an interval of the formation to be treated. Afterwards, a high density first stage scale inhibitor is
5308602 Synthesis of crystalline ultra-large pore oxide materials May 3, 1994
There is provided a method for preparing crystalline ultra-large pore oxide materials. The materials are formed from reaction mixtures comprising an amphiphilic compound, such as a cetyltrimethylammonium compound, a source of at least one oxide, such as silica, and water. The concentrati
5141655 Inhibition of scale formation from oil well brines utilizing a slow release August 25, 1992
A method for the inhibition of scale deposition on the surfaces of a well coproducing oil and scale forming brines comprising injecting into the well reservoir an acidic aqueous solution at a first pH containing dissolved therein a scale inhibitor, multivalent metal ions, and a heat
5089150 Method of increasing retention of scale inhibitors in subterranean formations February 18, 1992
A novel method of injecting or squeezing a cross-linked scale inhibitor down a well into a subterranean formation which significantly lengthens its effective life is accomplished by cross-linking a carboxylic acid-containing polymeric or organophosphorus-containing inhibitor with a p
5068042 Dissolution of sulfate scales November 26, 1991
The invention provides for the use of compositions to dissolve sulfate scales from surfaces containing these scales, comprising an aqueous solution of an aminopolycarboxylic acid (APCA) containing 1 to 4 amino groups, e.g., diethylenetriaminepentaacetic acid (DTPA) or ethylenediamine
5008025 Sulfonate-containing polymer/polyanionic cellulose combination for high temperature/high pressur April 16, 1991
A method and composition for improving high temperature and high pressure filtration control in a water base drilling fluid is described. Polyanionic cellulose is combined with a synthetic sulfonate containing vinyl polymer into a drilling fluid to provide for unexpectedly improved f
4947934 Method of increasing retention of scale inhibitor in subterranean formations August 14, 1990
A method for inhibiting the formation of scale in a well penetrating a subterranean formation for the production of fluids from the formation comprising injecting into the formation an acidic aqueous solution having a pH effective to form a water-soluble complex of the inhibitor and the
4855526 Process for preparing ethylene-higher olefin copolymer oils with Ziegler-Natta catalyst in mixed August 8, 1989
Low viscosity copolymers of ethylene and higher olefins are prepared with Ziegler-Natta catalysts in the presence of an aliphatic-aromatic solvent mixture, e.g., 1:1 (by volume) of hexane:toluene. The copolymerization can be conducted without hydrogen and subsequent cracking or dewaxing
4787455 Method for scale and corrosion inhibition in a well penetrating a subterranean formation November 29, 1988
A method for inhibiting the formation of scale and corrosion in a well penetrating a subterranean formation for the production of fluids from the formation comprising injecting a predetermined amount of microparticles of a basic anion exchange resin providing a source of polycations into
4779679 Method for scale and corrosion inhibition in a well penetrating a subterranean formation October 25, 1988
A method for inhibiting the formation of scale and corrosion in a well penetrating a subterranean formation for the production of fluids from the formation comprising injecting a predetermined amount of microparticles of a cation exchange resin loaded with the desired cations into the fo
