US Patent:

45199825, May 28, 1985

Filed:

Mar 15, 1982

Appl. No.:

6/357922

Inventors:

Lorne A. Davis - Houston TX
Helen K. Haskin - Houston TX

Assignee:

Texaco Inc. - White Plains NY

International Classification:

E21B 4900

US Classification:

422 68

Abstract:

A method of two dimensional chemical flood testing includes evacuating a porous medium contained in a test cell. The porous medium in the test cell is irradiated with a beam of microwave energy at a plurality of predetermined locations on said test cell. The microwave energy that has passed through the porous medium at each location is detected at the location. The porous medium in the test cell is filled with brine. The irradiating and detecting steps are repeated, the porous medium is then flooded with crude oil, or a substitute, and again the irradiating and detecting steps are repeated. The porous medium is flooded with brine and again the irradiating and detecting steps are repeated. A calibration curve for each location is derived from the detected microwave energy at the location from the prior irradiating and detecting steps. The chemical flood system is tested by flooding the porous medium with the chemical flood system at a predetermined flow rate during which time the irradiating and detecting steps are repeated periodically so that the test cell is periodically scanned in two directions by microwave energy.

Appl. No.:

6/336142

Inventors:

Lorne A. Davis - Houston TX
Dale F. Brost - Houston TX
Helen K. Haskin - Houston TX

Assignee:

Texaco Inc. - White Plains NY

International Classification:

G01V 317
G01R 2700
G01N 2700

US Classification:

324376

Abstract:

A microwave core monitor includes a sample cell which contains a test core of an earth formation. A microwave transmitter irradiates the test core with a beam of electromagnetic energy at a microwave frequency. A microwave receiver provides an indication representative of a characteristic of a liquid, or the absence of a liquid, in the test core in accordance with electromagnetic energy that has passed through the core. The sample cell further includes microwave absorber rods which prevent portions of the beam of electromagnetic energy not passing through the test core from reaching the receiver.

Appl. No.:

6/449128

Inventors:

Helen K. Haskin - Houston TX
Phillip E. Figdore - Bellaire TX

Assignee:

Texaco Inc. - White Plains NY

International Classification:

E21B 4322

US Classification:

166274

Abstract:

The disclosed invention is a method of injecting polyalkylene glycols, or copolymers thereof, having a molecular weight between about 100 and 1200 into a hydrocarbon formation in conjunction with a chemical flooding process to reduce the loss of injected chemicals to the formation by adsorption and precipitation.

US Classification:

436 31

Abstract:

A method of testing a chemical for use in an enhanced recovery of oil from an earth formation includes obtaining a test core of an earth formation. The test core is cleaned and then subjected to a predetermined sequence of events similar to that which the reservoir has experienced. The test core is flooded with a chemical to be tested and the chemical is then driven from the test core with a drive liquid. The test core is irradiated with a beam of electromagnetic energy at a microwave frequency. An indication representative of the effectiveness of the chemical in the test core is derived in accordance with the electromagnetic energy that has passed through the test core.

International Classification:

G01N 500
G01N 708

US Classification:

422109

Abstract:

A method and apparatus for making a laboratory determination of the rate and type of hydrocarbon generated from a hydrocarbon source utilizes hydrous pyrolysis to generate hydrocarbons from the sample and then utilizes cryogenic methods to remove the fluid portions to a transfer vessel. The gaseous components are removed to a further vessel of known dimensions for determination of weight. The hydrocarbons in the transfer vessel are passed through a dryer to separate the water and their makeup determined. The hydrocarbons remaining in the reactor vessel are removed by working with solvents and their weights are determined after separation and evaporation of the solvents.
