US Patent:

50635093, Nov 5, 1991

Filed:

Jan 26, 1990

Appl. No.:

7/470478

Inventors:

Mary E. Coles - Addison TX
Ernest L. Muegge - Grand Prairie TX

Assignee:

Mobil Oil Corporation - Fairfax VA

International Classification:

G01D 1800

US Classification:

364420

Abstract:

X-ray attenuation measurements at two or more energies are carried out on core samples of earth materials for use in determining relative Compton scattering and photoelectric contributions to attenuation. The measurements are utilized to calculate material bulk density from the change in attenuation between such dual X-ray energies and the attenuation for one of the dual X-ray energies.

Appl. No.:

6/886997

Inventors:

Alfred R. Jennings - Plano TX
Ernest L. Muegge - Grand Prairie TX
Peggy M. Wilson - Dallas TX

Assignee:

Mobil Oil Corporation - New York NY

International Classification:

E21B 3700
E21B 3708

US Classification:

166312

Abstract:

A process wherein energy generated from a high impulse device is used to jar, loosen, or dislodge scale from a wellbore, downhole production equipment, or near well formation flow channels. Such jarred, loosened, or dislodged scale allows for increased amounts of scale-forming ions to be removed. Alterwards, an emulsified liquid membrane system containing surfactants therein sufficient to remove scale-forming ions is placed in said wellbore. Said emulsified membrane system is removed when the scale-forming ions have been absorbed therein.

Mobil Oil Corporation - Fairfax VA

International Classification:

G01V 500
G01N 2306

US Classification:

250255

Abstract:

X-ray attenuation measurements at two or more energies are carried out on core samples of earth materials for use in determining the relative contributions of Compton scattering and photoelectric absorption to the attenuation of the beams of X-rays by the samples. The measurements are utilized to calculate material bulk density, responsive to the difference in attenuation measured with respect to beams of two different X-ray energies and the attenuation of the beams of one of X-rays.

Appl. No.:

6/770928

Inventors:

Peggy M. Wilson - Dallas TX
Ernest L. Muegge - Grand Prairie TX

Assignee:

Mobil Oil Corporation - New York NY

International Classification:

E21B 3700
E21B 3708

US Classification:

166312

Abstract:

A method for removing scale-forming ions from oil and gas production equipment. An external aqueous phase of a liquid membrane system contacts said scale and solubilizes said scale-forming compounds. Scale forming ionic compounds are then transferred into an immiscible liquid hydrocarbonaceous membrane phase having a complexing agent for scale forming ions. Said hydrocarbonaceous membrane phase envelops droplets of an internal aqueous phase which has a stronger complexing agent for scale forming ions than is contained in said hydrocarbonaceous membrane phase. Scale forming ions are transferred from said hydrocarbonaceous membrane phase and are accumulated and concentrated in said internal aqueous phase. Films of scale are thus progressively removed from surfaces where they have deposited.

Appl. No.:

6/872341

Assignee:

Mobil Oil Corporation - New York NY

International Classification:

G01N 2306
G01V 500

US Classification:

378 4

Abstract:

A core sample invaded by drilling mud is scanned with X-rays and computed tomographic images are produced. The images are calibrated to a density scale based on the barite content of the drilling mud. The mud solid volume in the pores of the core sample are determined from the density contrast created in the computed tomographic images by the presence of barite in the core sample. This mud solid volume is used to provide a corrected porosity measurement on the core sample.

US Classification:

Abstract:

A substantially cylindrical sample of a porous material is surrounded by an elastic jacket and placed in a confining pressure cell. Pressure is supplied to the cell to press the jacket into contact with the surface of the sample. The pressure is varied over a plurality of pressure points and is scanned at a plurality of locations with X-rays at each such pressure point. A computed tomographic image is produced for each X-ray scan. Conformance of the jacket to the sample is determined from these computed tomographic images and a range of confining pressure is determined over which parameters of the sample may be measured without being affected by improper conformance of the jacket to the surface of the sample. The sample structure is monitored with these tomographic images for fractures produced due to the increase of pressure. The fracture starting point is determined to be interior or surface related.
