US Patent:

43963943, Aug 2, 1983

Filed:

Dec 21, 1981

Appl. No.:

6/333142

Inventors:

James L. Skinner - Richardson TX
Donald K. Wunderlich - Richardson TX
J. David Matthews - Denver CO
Bernard F. Bonnecaze - Littleton CO

Assignee:

Atlantic Richfield Company - Los Angeles CA

International Classification:

C10L 500
C10L 524

US Classification:

44 1G

Abstract:

A method for producing a dried coal fuel having a reduced tendency to spontaneously ignite from a low rank coal by drying the low rank coal and thereafter cooling the dried coal to a temperature below about 100. degree. F. Optionally the dried coal is partially oxidized prior to cooling, and optionally the dried coal is mixed with a deactivating fluid.

International Classification:

C06

US Classification:

208 13

Abstract:

Heavy hydrocarbon containing sludges such as refinery waste streams, oil storage tank sludges and marine oil tanker ballast are treated by passing the sludges in a flow stream through an indirect dryer to vaporize liquids having a boiling point at atmospheric pressure of less than about 700. degree. F. and to provide substantially dried solid particles discharged from the dryer. The dried particles, containing heavy hydrocarbons as a coating or as a part of the solids, are conducted to a combustor/oxidizer and exposed to a high velocity flow stream of oxygen containing gas, typically low pressure forced air, to burn the residual hydrocarbons in the solids and to reduce heavy metals and the like to oxides thereof. A sludge handling system includes a rotary disk type indirect dryer connected to a lift pipe type combustor/oxidizer for thorough exposure of the dried solids to an oxygen containing atmosphere. A centrifigal or cyclone type gas-solids separator receives the flow stream discharged from the lift pipe and a portion of the dried solids may be diverted after discharge from the dryer back to the dryer inlet to reduce the moisture content of the sludge flow stream introduced to the dryer to minimize caking and clogging of the dryer itself.

Appl. No.:

6/811929

Inventors:

James L. Skinner - Plano TX

Assignee:

Atlantic Richfield Company - Los Angeles CA

International Classification:

E21B 4308

US Classification:

166278

Abstract:

A gravel pack well completion includes an elongated gravel pack screen connected at its upper end to a production tube which in turn is connected to a production fluid pump. The gravel pack screen includes an elongated tube interposed therein and having a primary inlet located generally in the vicinity of the lower end of the screen for maintaining sufficient liquid flow velocity within the screen to prevent settling and accumulation in the wellbore of entrained fine solids entering said screen with production liquids. A gas port is provided in the upper end of the draft tube to conduct gas into said production tube and to prevent significant accumulation of gas in the wellbore at the gravel pack.

International Classification:

E21B 2106
C09K 700

US Classification:

175 66

Abstract:

A method and apparatus for drilling a wellbore in the earth from a location in a body of water wherein the drilling operation generates a substantial amount of a mixture of solid drilling cuttings, water and at least one hydrocarbonaceous oil wherein the water and oil are removed from the solid drilling cuttings and any retain solid particles in said water and oil are removed therefrom prior to reuse, disposal, or other disposition of said water and oil.

US Classification:

44 6

Abstract:

A method and apparatus for contacting particulate coal and a deactivating fluid, the apparatus comprising a mist contacting vessel wherein the coal and a deactivating fluid mist are contacted to produce a coal-deactivating fluid mixture. A method for producing the coal-deactivating fluid mixture is disclosed.

International Classification:

E21B 2106

US Classification:

175 66

Abstract:

A method and apparatus for drilling a wellbore in the earth from a location in a body of water wherein the drilling operation generates a substantial amount of a mixture of solid drilling cuttings, water, and at least one hydrocarbonaceous oil, wherein the water and oil are removed from the solid drilling cuttings so that the cuttings are put into a condition in which they can be disposed of in the body of water or elsewhere without adverse effects.

Appl. No.:

5/749505

International Classification:

C10G 102
C10B 5306

US Classification:

208 11R

Abstract:

In an oil shale retorting process, hot heat-carrying spherically-shaped solids are cycled to a retort zone to mix with and retort crushed oil shale, thereby producing gas and oil products and a mixture of irregularly-shaped, laminar spent shale and spherically-shaped solids. The spherically-shaped solids are separated and recovered from the spent shale for recycle through the process. In one stage of the separation procedure, a mixture of spent shale and spherically-shaped solids is fed to a continuously restored inclined surface whereon the spherically-shaped solids roll from the surface while the irregularly-shaped spent shale solids are separately removed from the inclined surface. Continuous restoration of the inclined surface is achieved through movement of the feed and the impingement area of the inclined surface relative to each other. The separation system may be used for separating other types of spherically-shaped solids which will roll from nonspherical, irregularly-shaped solids which do not roll.

Assignee:

Atlantic Richfield Company - Los Angeles CA

International Classification:

E21B 3708

US Classification:

166 77

Abstract:

A method and apparatus for removing solid particles which have settled out in a region of a wellbore which employs at least one pair of conduit means, one of said conduit means having nozzle means thereon, said conduit means being disposed in the region of settled particle and passing fluid through one conduit means and the nozzle means into region of settled particles to mix with same and recovering the mixture of fluid and particles from said region by way of the other conduit means.
