  • Acidizing carbonate reservoirs with chlorocarboxylic acid salt solutions
    Patent number: 4122896
    Abstract: A carbonate reservoir is acidized slowly by injecting an aqueous solution of a chlorocarboxylic acid salt so that the rate of the acidization is limited to the rate at which an acid is formed by the hydrolyzing of the chlorocarboxylate ions.
    Type: Grant
    Filed: October 14, 1977
    Date of Patent: October 31, 1978
    Assignee: Shell Oil Company
    Inventors: Ronald F. Scheuerman, Edwin A. Richardson, Charles C. Templeton
  • Increasing the clay dissolving capability of a buffer-regulated mud acid
    Patent number: 4090563
    Abstract: The clay dissolving capability of an aqueous mud acid solution of weak acid, weak acid salt and fluoride salt (of the type described in the E. A. Richardson U.S. Pat. No. 3,889,753) can be increased by including in the solution a partial salt of an aminopolyacetic acid chelating or complex-forming agent.
    Type: Grant
    Filed: December 27, 1976
    Date of Patent: May 23, 1978
    Assignee: Shell Oil Company
    Inventors: James H. Lybarger, Edwin A. Richardson, Ronald F. Scheuerman, Charles C. Templeton
  • Increasing the clay-dissolving capability of a relatively high pH self-generating mud acid
    Patent number: 4089787
    Abstract: The clay-dissolving capability of a self-generating mud acid comprising an aqueous solution or dispersion of a fluoride salt, an ester of a 1-5 carbon atom aliphatic alcohol and a 2-5 carbon atom fatty acid suitable for use at temperatures exceeding about 180.degree. F is improved by adding an effective amount of an aminopolyacetic acid salt chelating or complexing agent.
    Type: Grant
    Filed: March 16, 1977
    Date of Patent: May 16, 1978
    Assignee: Shell Oil Company
    Inventors: James H. Lybarger, Charles C. Templeton, Edwin A. Richardson, Ronald F. Scheuerman
  • Dissolving siliceous materials with self-acidifying liquid
    Patent number: 3953340
    Abstract: Siliceous materials in or around a well are dissolved by contacting them with a self-acidifying aqueous liquid system comprising an aqueous solution of at least one water-soluble fluoride salt mixed with a relatively slowly-reactive acid-yielding material that subsequently converts the salt solution to a hydrofluoric acid solution that has a relatively high pH but is capable of dissolving siliceous material.
    Type: Grant
    Filed: May 3, 1974
    Date of Patent: April 27, 1976
    Assignee: Shell Oil Company
    Inventors: Charles C. Templeton, Evan H. Street, Jr, Edwin A. Richardson
  • Subterranean oil shale pyrolysis with permeating and consolidating steps
    Patent number: 3945679
    Abstract: In producing shale oil by circulating hot fluid into and out of a rubble-containing cavern within a subterranean oil shale, plugging is avoided by permeating a portion of oil shale, consolidating a permeated portion, inflowing fluid outside the consolidated portion, and outflowing fluid from within the consolidated portion so the fluid is filtered through the consolidated portion.
    Type: Grant
    Filed: March 3, 1975
    Date of Patent: March 23, 1976
