US Patent:

41558570, May 22, 1979

Filed:

Nov 17, 1977

Appl. No.:

5/852266

Inventors:

Loyd W. Jones - Tulsa OK

Assignee:

Standard Oil Company (Indiana) - Chicago IL

International Classification:

E21B 4327
E21B 3700
C02B 506

US Classification:

252 855B

Abstract:

A process and composition are described for use in removing calcium sulfate scale from a well. An aqueous converter solution of sodium (for potassium or possibly ammonium) gluconates, hydroxides, and carbonates is used to convert the calcium sulfate into an acid soluble form, which can be removed by an acid rinse. In the aqueous converter solution, the weight ratio of hydroxide to carbonate is between about 3:2 and about 5:1, and the weight ratio of gluconate to the total amount of hydroxide and carbonate is between about 2:1 and about 5:1. The concentration of the combination of gluconate, hydroxide, and carbonate is between about 15% and about 50%. Preferably, the solution is by weight approximately 25% sodium gluconate, 5. 3% sodium hydroxide, 1. 8% sodium carbonate, and the remainder water.

International Classification:

C09K 300
C23F 1104
C23F 1118

US Classification:

252189

Abstract:

A corrosion inhibitor composition useful for preventing corrosion by solvents used in treating sour gas streams, comprising a quaternary pyridine salt, a surface-active agent and/or a thio compound and an effective amount of a water soluble nickel compound. The composition can also contain a demulsifier to prevent foaming of the resultant solution.

International Classification:

E21B 4327
E21B 4322

US Classification:

252 8553

Abstract:

A micellar acidic surfactant solvent composition of enhanced oil/organic solvency and method of preparing and using same. The oil solvency of a propoxylated/ethoxylated surfactant and alcohol micellar acidizing system is enhanced by controlling or selecting the molar ratio of alcohol to surfactant as a linearly increasing function of acid concentration. The oil solvency is further enhanced and selectively controlled by addition of an oil solvent (e. g. , aromatic hydrocarbons, aromatic acid esters, ketones, CS. sub. 2, etc. ) to the micelle.

Appl. No.:

6/698870

Inventors:

Loyd W. Jones - Grove OK

International Classification:

E21B 4327

US Classification:

252 855C

Abstract:

An acidizing additive to be added to an oil well acidizing solution comprising a mixture of a high molecular weight substantially water insoluble alcohol (e. g. isooctyl alcohol), an effective amount of a phosphate ester surfactant (e. g. Klearfax AA-270), to render the alcohol acid soluble, and a low molecular weight alcohol or diol with water diluent. Such an additive can be easily delivered and mixed with an acid solution in the field to produce an acidizing medium of superior oil dispersion characteristics.

Assignee:

Amoco Production Company - Tulsa OK

International Classification:

B01D 2702

US Classification:

210287

Abstract:

This invention relates to water pollution control and concerns system for removing dispersed oil from water by contacting the oily water with sulfur to cause the oil to coalesce or agglomerate. In a preferred embodiment, the water containing the dispersed oil is passed through a bed of granular media presenting a surface area of solid phase sulfur to coalesce the dispersed oil. The coalesced oil is then separated from the water.

International Classification:

E21B 4327

US Classification:

166307

Abstract:

A method for cleaning and stimulating an oil, gas or injection well, in which wax, tar and/or bituminous materials are either already deposited or would be precipitated by the injection of an acidizing solution consisting of a mixture of an octanol and a lower alcohol with an aqueous acid solution, involving the injection of an aromatic solvent either before and/or after the alcohol-acidizing solution. To enhance the interfacial miscibility of the aromatic solvent and the alcohol-acidizing solution, a small amount of amine having no more than eight carbon atoms may be added to the aromatic solvent. This method is useful in both production and injection wells.
