Patent number: 8846732Abstract: Biogenic sulfide production is synergistically inhibited by treating sulfate-reducing bacteria (SRB) with a biocide and a metabolic inhibitor. The biocide directly kills a first portion of the SRB. The metabolic inhibitor inhibits sulfate-reducing growth of a second portion of the SRB without directly killing the second portion of the SRB. The treatment of SRB with both a biocide and a metabolic inhibitor provides effective biogenic sulfide inhibition at significantly lower concentrations than would be required if the biocide or metabolic inhibitor was used alone.Type: GrantFiled: October 6, 2010Date of Patent: September 30, 2014Assignees: ConocoPhillips Company, University Technologies International, Inc.Inventors: Gary E. Jenneman, Anne Greene, Gerrit Voordouw

Patent number: 5820766Abstract: A composition and a process for substantially reducing or removing sulfide from a sulfide-containing fluid are disclosed. The composition comprises, or is prepared by combining components comprising, a sulfide-containing fluid and a sulfide-scavenging amount of a sulfide scavenger selected from the group consisting of bromates, iodates, and combinations of two or more thereof. The process comprises contacting a sulfide-containing fluid with a sulfide-scavenging amount of a sulfide scavenger under a condition sufficient to substantially reduce the sulfide concentration in the fluid.Type: GrantFiled: April 23, 1997Date of Patent: October 13, 1998Assignee: Phillips Petroleum CompanyInventors: Diane Gevertz, Gary E. Jenneman

Patent number: 5363913Abstract: A novel process for sustaining microbial activity in subterranean formations which comprises introducing in addition to microbial nutrients, a sequestering anion. This process may include the sequential injection of sources of individual nutrient components which are deficient in said subterranean formation, whereby the injected phosphorus source is more readily transportable due to the presence of a sequestering agent in the formation.Type: GrantFiled: August 30, 1993Date of Patent: November 15, 1994Assignee: Phillips Petroleum CompanyInventors: Gary E. Jenneman, James B. Clark

Patent number: 5083611Abstract: The present invention provides a method of injecting nutrients into a subterranean formation in order to achieve a desired in-situ microbial objective. Sources of individual nutrient components which are deficient in the formation are sequentially injected so that a complete nutrient medium capable of sustaining substantial microbial activity is formed in the formation upon injection of the last of said sources. Said sources are preferably injected into the formation in order of decreasing quantitative formation retainability.Type: GrantFiled: January 18, 1991Date of Patent: January 28, 1992Assignee: Phillips Petroleum CompanyInventors: James B. Clark, Gary E. Jenneman

Patent number: 4558739Abstract: Subterranean paths of water flow are impeded or changed by the facilitation of microbial growth therein. Either indigenous bacterial growth may be stimulated with nutrients or the formation may be first seeded with bacteria or their spores which inhibit fluid flow after proliferation. These methods and bacteria are usable to alter the flow of water in a waterflooded oil formation and to impede the outflow of contaminated water.Type: GrantFiled: April 5, 1983Date of Patent: December 17, 1985Assignee: The Board of Regents for the University of OklahomaInventors: Michael J.
