Patents by Inventor Mike Conway

Mike Conway has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Vicinal diol containing monomers and polymers and methods of treating a subterranean formation
    Patent number: 4767550
    Abstract: The present invention provides vicinal diol containing monomers and polymers and methods of preparing and using such monomers and polymers. When crosslinked in aqueous fluids, the polymers form high viscosity gels which are stable at high temperatures.
    Type: Grant
    Filed: March 31, 1987
    Date of Patent: August 30, 1988
    Assignee: Halliburton Company
    Inventors: David Hanlon, Marlin Holtmyer, Mike Conway, Charles Hunt
  • Vicinal diol containing monomers and methods of preparing
    Patent number: 4730081
    Abstract: The present invention provides a water soluble vinyl monomer containing a vicinal diol group of the general formula: ##STR1## wherein R.sub.1 is hydrogen or methyl; R.sub.3 and R.sub.4 are independently methyl or ethyl; Y is oxygen or NH; X.sup.- is a halogen, sulfate, CH.sub.3 SO.sub.4.sup.- or C.sub.2 H.sub.3 SO.sub.4.sup.- or CH.sub.3 COO.sup.- and n is 2 or 3. Polymers containing the monomer when crosslinked in aqueous fluids form high viscosity gels which are stable at high temperatures and can be used in carrying out completion, stimulation, enhanced production and other treatments in subterranean formations.
