US Patent:

47874465, Nov 29, 1988

Filed:

May 1, 1987

Appl. No.:

7/045093

Inventors:

Eddie P. Howell - McKinney TX
Lonnie J. Smith - Allen TX
Dennis R. Wood - Plano TX

Assignee:

Atlantic Richfield Company - Los Angeles CA

International Classification:

E21B 33127

US Classification:

166 664

Abstract:

Apparatus for interconnecting a tubing string with downhole tool and for controlling the flow of fluid into a wellbore through the tubing string comprising an elongated body member and a resiliently deformable sleeve disposed around the body member and radially deformable to form a seal against the wellbore wall to seal off a zone of interest. The body member includes a passage for extension of a wireline cable from the tubing string to the downhole tool. An electric motor operated rotary plug valve is disposed in the apparatus body and is operable to be rotated to valve pressure fluid from the tubing string into an expansible chamber to cause the seal sleeve to deform to seal the wellbore. The valve member is movable to positions to relieve pressure fluid from the seal, to valve pressure fluid to the wellbore at an injection point below the seal and to block all ports. A lower head member of the apparatus includes an anchor for the wireline cable sheath and an upper head member includes a check valve to prevent backflow of fluids from the wellbore into the tubing string.

International Classification:

G01V 500

US Classification:

250253

Abstract:

Radioactive gaseous decay products emanating from a buried deposit of uranium or other radioactive ore migrate upwardly through the earth and are exhaled into the atmosphere. These products may be trapped at the surface in a series of low profile, dome-shaped plastic shelters 5 to 20 feet in diameter. Radiant energy permeating each shelter cover heats the soil beneath the enclosed surface area to accelerate the escape of gas through the soil. The air confined within the shelters is continuously recirculated over the exposed surfaces of a plurality of highly adsorbent discs. After equilibrium decay conditions are reached, the discs are analyzed to determine the radioactivity of the discs, which is proportional to the concentration of radioactive gas in the vicinity.

International Classification:

E21B 704

US Classification:

166272

Abstract:

A method of producing bitumen from a subterranean tar sand formation characterized by the following muti-step process. First, a continuous wellbore having a second section thereof contained within the formation and a first and a third section extending said second section to the earth's surface is formed. Next, a perforated liner is inserted into the wellbore extending the entire length thereof and having perforations so positioned thereon to be adjacent the second section of the wellbore. Thereafter, a heated fluid is circulated through the wellbore, contacting the formation via the perforations, thereby reducing the viscosity of the bitumen contained therein rendering it mobile. Subsequently, the mobilized bitumen is recovered via the wellbore.

International Classification:

E21B 4328

US Classification:

299 4

Abstract:

The present invention relates to an improved method for the solution mining of a mineral from a subterranean formation. More specifically, the invention relates to an improved method which enhances significantly the recovery of a mineral from a subterranean formation via solution mining utilizing an injection and production well. The improvement comprises positioning an injection well in the reduced zone and a production well in the oxidized zone of a formation.

Atlantic Richfield Company - Los Angeles CA

International Classification:

G01V 140

US Classification:

340 155AC

Abstract:

A pulse of ultrasonic acoustic energy applied to an earth formation by means of a well logging tool initiates a first compressional formation pulse followed by a secondary pulse of lower amplitude and velocity traveling exclusively in the formation fluid. These two pulses are located, identified and quantized with cross-correlation techniques to give a direct indication of formation permeability, to identify accurately the nature of the formation fluid, and to provide a more accurate determination of formation porosity.

Abstract:

A method of recovering bitumen from a subterranean tar sand formation characterized by a plurality of steps. First, a continuous wellbore having a second section thereof contained within the formation and first and third sections thereof extending the second section to the earth's surface is formed. Next, the first and third sections of the wellbore are cased. Thereafter, a heated fluid is circulated through the wellbore contacting the formation to reduce the viscosity of the bitumen contained therein rendering the bitumen mobile. Subsequently, bitumen mobilized by the heated fluid is recovered via the wellbore.

International Classification:

G01V 900

US Classification:

Abstract:

A method for measuring the thermal conductivity of well casing in situ. The instrument consists of a probe several feet in length lowered into a well and decentralized so that it maintains contact with the casing wall. Two temperature sensors situated adjacent opposite ends of the probe are thermally insulated from an electrically heated intervening portion of the probe body. The probe is moved from one depth to another at a constant predetermined velocity, and the sensors continuously measure the temperature of the casing wall before and after passage of the heated probe portion thereover. The effective thermal conductivity of the casing is directly proportional to the flux applied by the heater and inversely proportional to the temperature change as the heater passes a point along the casing.

Abstract:

A method of recovering bitumen from a subterranean tar sand formation by the following multi-step method. First, an injection well is drilled to the formation and cased. Perforations are provided in the portion of the injection well contacting the formation. Next, a plurality of production wells are drilled and completed into the formation positioned above and along the length of the injection well. Thereafter, a heated fluid is circulated through the injection well contacting the formation via the perforations and thereby reducing the viscosity of the bitumen contained therein rendering same mobile. Subsequently, the mobilized bitumen is recovered through the plurality of production wells.
