Appl. No.:

5/925178

Inventors:

John D. McCollum - Naperville IL

Assignee:

Standard Oil Company - Chicago IL

International Classification:

E21B 4324
E21B 4706
E21B 4712

US Classification:

166251

Abstract:

Disclosed is a method for detecting the flame front during the in situ combustion of a subterranean carbonaceous stratum which involves providing one or more radio transmitters below the surface of the ground, each of said transmitters being capable of sensing and transmitting information concerning the physical and chemical properties of its surroundings, and monitoring said transmissions as an indication of the extent and movement of said flame front. Also disclosed is a method for detecting non-uniform packing characteristics of rubblized material which involves providing one or more radio transmitters within the boundaries of a retort capable of sensing and transmitting information concerning the physical parameters of its surroundings, and monitoring said transmissions as an indication of the size and density distributions of the rubble in said retort.

International Classification:

C10G 104

US Classification:

208 8

Abstract:

A process for recovering and upgrading products from solid coal by contacting the coal with a dense-water-containing fluid at a temperature in the range of from about 600. degree. F. to about 900. degree. F. in the absence of an externally supplied catalyst and hydrogen or other reducing gas. The density of water in the water-containing fluid is at least 0. 10 grams per milliliter, and sufficient water is present to serve as an effective solvent for the recovered liquids and gases.

International Classification:

G01V 302

US Classification:

324323

Abstract:

Disclosed is a method for detecting the flame front in the in situ combustion of a subterranean carbonaceous stratum which comprises providing two or more resistance probes inserted into the ground electrically connected in one or more circuits capable of measuring the resistance between pairs of said probes, and monitoring the change in resistance in one or more of said circuits as an indication of the extent and movement of said flame front.

Standard Oil Company (Indiana) - Chicago IL

International Classification:

C10G 100

US Classification:

208430

Abstract:

A method for producing a kerogen concentrate from oil shale comprises treating shale with an aqueous caustic treating solution to produce a shale product of substantially transformed mineral content, and then treating the shale product with an aqueous acid solution to produce a kerogen concentrate. The acid solution extracts minerals from the shale product to lower the ash content of the kerogen concentrate. A spent acid solution containing the extracted minerals can be treated to recover minerals therefrom.
