Recovering Oil By Injecting Aqueous Alkali, Cosurfactant And Gas
view source
US Patent:

44933711, Jan 15, 1985
Filed:

Jul 29, 1983
Appl. No.:

6/518711
Inventors:

Joseph Reisberg - Houston TX
Lawrence J. Bielamowicz - Bellaire TX
David R. Thigpen - Houston TX
Assignee:

Shell Oil Company - Houston TX
International Classification:

E21B 4322
US Classification:

166274
Abstract:

A process of recovering oil from a subterranean reservoir in which the oil is acidic but forms monovalent cation soaps of only relatively low interfacial activity when reacted with aqueous alkaline solutions, comprises displacing the oil toward a production location with a mixture of gas and cosurfactant-containing aqueous alkaline solution.

US Patent:

42793050, Jul 21, 1981
Filed:

May 27, 1980
Appl. No.:

6/153465
Inventors:

Randolph H. Knapp - New Orleans LA
Jimmie B. Lawson - Houston TX
Joseph Reisberg - Houston TX
David R. Thigpen - Houston TX
Harold J. Hill - Houston TX
Assignee:

Shell Oil Company - Houston TX
International Classification:

E21B 4322
E21B 4327
US Classification:

166307
Abstract:

The injectivity of an oil-containing reservoir is increased by injecting successive portions of a solution or slightly turbid dispersion of reservoir-tailored amounts of polyalkoxyalcohol sulfate surfactant and lower alkanol in highly saline aqueous liquid and a reservoir acidizing solution.

US Patent:

46094741, Sep 2, 1986
Filed:

Dec 6, 1984
Appl. No.:

6/678841
Inventors:

Joseph Reisberg - Houston TX
Hendrik T. Verkouw - Frankfurt am Main, DE
Theodorus A. B. M. Bolsman - CM Amsterdam, NL
Assignee:

Shell Oil Company - Houston TX
International Classification:

E21B 4322
US Classification:

252 855D
Abstract:

An aqueous organic sulfonate surfactant system containing an alkylpolyalkoxyphenylethersulfonate cosurfactant has a salt tolerance comparable to one containing NEODOL. RTM. 25-3S and has greater heat stability.

US Patent:

42034914, May 20, 1980
Filed:

Sep 5, 1978
Appl. No.:

5/939521
Inventors:

Joseph Reisberg - Houston TX
Assignee:

Shell Oil Company - Houston TX
International Classification:

E21B 4322
US Classification:

166274
Abstract:

In an oil reservoir in which the water contains more than about 9% dissolved salt, oil is produced by injecting an oil-displacing dispersion of at least one surface active alkylaryloxy polyethoxyethane sulfonate in the reservoir water or an equally saline water followed by a mobility controlling dispersion of noncondensible gas in an equally saline water.

Polyalkoxy Sulfonate, Co.sub.2 And Brine Drive Process For Oil Recovery

US Patent:

45025380, Mar 5, 1985
Filed:

Jan 9, 1984
Appl. No.:

6/569423
Inventors:

Scott L. Wellington - Houston TX
Joseph Reisberg - Houston TX
Eugene F. Lutz - Houston TX
David B. Bright - Houston TX
Assignee:

Shell Oil Company - Houston TX
International Classification:

E21B 4322
E21B 4706
US Classification:

166252
Abstract:

Oil is displaced within a subterranean reservoir by injecting a combination of substantially liquefied CO. sub. 2, brine and surfactant material into the reservoir, with the surfactant material being a polyalkoxy aliphatic sulfonate surfactant material which has specified dispersing and partitioning properties in contact with the brine and the fluids in the reservoir at the reservoir temperature and a pressure sufficient to substantially liquefy the CO. sub. 2 within the reservoir.

US Patent:

40747557, Feb 21, 1978
Filed:

Mar 21, 1977
Appl. No.:

5/779663
Inventors:

Harold J. Hill - Houston TX
Joseph Reisberg - Houston TX
Fred G. Helfferich - Houston TX
Larry W. Lake - Houston TX
Gary A. Pope - Austin TX
Assignee:

Shell Oil Company - Houston TX
International Classification:

E21B 4322
US Classification:

166252
Abstract:

A process for recovering oil by successively injecting at least a chemical slug containing an active aqueous surfactant system or thickened aqueous liquid and an aqueous drive liquid into a reservoir having a significant amount of ion exchange capacity, is improved. The ionic composition of each injected fluid is arranged to provide a ratio, between the concentration of its effectively predominate monovalent cation and the square root of the concentration of its effectively predominate divalent cation, which ratio at least substantially equals such a ratio within the aqueous fluid immediately ahead of the injected fluid.

US Patent:

42327415, Nov 11, 1980
Filed:

Jul 30, 1979
Appl. No.:

6/062204
Inventors:

Edwin A. Richardson - Houston TX
Ronald F. Scheuerman - Bellaire TX
David C. Berkshire - Houston TX
Joseph Reisberg - Houston TX
James H. Lybarger - Houston TX
Assignee:

Shell Oil Company - Houston TX
International Classification:

E21B 3316
E21B 4316
E21B 4327
US Classification:

166281
Abstract:

Portions of a subterranean reservoir are temporarily plugged by injecting an aqueous liquid solution which contains nitrogen gas-generating reactants, a foaming surfactant and a pH controlling system arranged so that the solution remains relatively unreactive within the well but forms a relatively immobile foam within the pores or other openings within the reservoir formation.
