Polyvalent Metal Ion Chelating Agents For Xanthan Solutions

View page
US Patent:
44668899, Aug 21, 1984
Filed:
Aug 20, 1981
Appl. No.:
6/294593
Inventors:
James W. Miller - Mystic CT
Bryce E. Tate - Niantic CT
Assignee:
Pfizer Inc.
International Classification:
C09K 300
US Classification:
252 855D
Abstract:
A stable xanthan solution with superior filterability and subterranean injectivity characteristics comprising biopolymer and a chelating agent selected from aliphatic alpha-hydroxy acids having from about 2-7 carbon atoms; aliphatic and aromatic beta-keto compounds having from about 4-9 carbon atoms; or 2- and 4-pyrones having a hydroxyl group alpha to the carbonyl and having 5 or 6 carbon atoms; said chelating agent being present in an amount of at least about 1. 0 ppm of the total solution. A method of enhancing oil recovery comprising employing as a mobility control solution in oil-bearing formations a mixture of xanthan biopolymer and a chelating agent is also disclosed.

US Patent:
44587538, Jul 10, 1984
Filed:
Oct 15, 1982
Appl. No.:
6/434669
Inventors:
Judson C. Philips - Gales Ferry CT
Bryce E. Tate - Niantic CT
Assignee:
Pfizer Inc. - New York NY
International Classification:
E21B 4322
US Classification:
166246
Abstract:
A method of tertiary oil recovery from petroleum-containing formations at elevated temperature comprises injecting a substantially oxygen-free aqueous saline solution of water-soluble polysaccharide biopolymer treated at pH of at least 5 by the addition of alkali metal borohydride as viscosity stabilizer.

Surfactant Enhanced Injectivity Of Xanthan Mobility Control Solutions For Tertiary Oil Recovery

View page
US Patent:
44067984, Sep 27, 1983
Filed:
Aug 24, 1981
Appl. No.:
6/295272
Inventors:
James W. Miller - Mystic CT
Bryce E. Tate - Niantic CT
Assignee:
Pfizer Inc. - New York NY
International Classification:
E21B 4322
US Classification:
252 855D
Abstract:
An aqueous mobility control solution for tertiary oil recovery from saline oil fields comprises from about 200 to 2000 ppm xanthan biopolymer in the form of clean, unreconstituted fermentation broth and from about 20 to 200 ppm of a selected water-soluble polyglycol-based surfactant. A process for tertiary oil recovery which comprises the injection of the mobility control solution into saline oil-bearing subterranian formations is also disclosed.
