Appl. No.:

10/097448

Inventors:

William F. Howard - West Columbia TX
Jackie C. Sims - Houston TX
Dudley L. Robinson - Houston TX
Ronald W. Schmidt - Richmond TX

Assignee:

Weatherford/Lamb, Inc. - Houston TX

International Classification:

E21B 4324

US Classification:

166303, 166269, 166222

Abstract:

The present invention generally provides a method and apparatus for injecting a compressible fluid at a controlled flow rate into a geological formation at multiple zones of interest. In one aspect, the invention provides a tubing string with a pocket and a nozzle at each isolated zone. The nozzle permits a predetermined, controlled flow rate to be maintained at higher annulus to tubing pressure ratios. The nozzle includes a diffuser portion to recover lost steam pressure associated with critical flow as the steam exits the nozzle and enters a formation via perforations in wellbore casing. In another aspect, the invention ensures steam is injected into a formation in a predetermined proportion of water and vapor by providing a plurality of apertures between a tubing wall and a pocket. The apertures provide distribution of steam that maintains a relative mixture of water and vapor. In another aspect of the invention, a single source of steam is provided to multiple, separate wellbores using the nozzle of the invention to provide a controlled flow of steam to each wellbore.

Abstract:

The present invention generally provides a method and apparatus for injecting a compressible fluid at a controlled flow rate into a geological formation at multiple zones of interest. In one aspect, the invention provides a tubing string with a pocket and a nozzle at each isolated zone. The nozzle permits a predetermined, controlled flow rate to be maintained at higher annulus to tubing pressure ratios. In another aspect, the present invention assures that the fluid is supplied uniformly to a long horizontal wellbore by providing controlled injection at multiple locations that are distributed throughout the length of the wellbore. In another aspect, the invention ensures that saturated steam is injected into a formation in a predetermined proportion of water and vapor by providing a plurality of apertures between a tubing wall and a pocket.

Jackie C. SIMS - Houston TX, US

Assignee:

Chevron U.S.A. Inc. - San Ramon CA

International Classification:

E21B 43/24

US Classification:

166 57

Abstract:

Methods and apparatus for enhanced and improved viscous oil recovery are disclosed. A horizontal well is drilled through the viscous oil formation. A specially designed tubing string includes outlets that deliver steam more uniformly into the entire horizontal extent of the well borehole. Heat from the steam mobilizes and lowers the viscosity of the heavy crude wherein the crude is then produced to the surface via conventional lift arrangements.

Assignee:

Texaco Inc. - White Plains NY

International Classification:

G01R 2726

US Classification:

324 61R

Abstract:

A steam quality monitor monitoring the quality of steam flowing in the pipe includes capacitance sensing apparatus which senses the capacitance of the flowing steam and provides a capacitance signal corresponding to the said capacitance. Another sensor which may be either a temperature sensor or a pressure sensor senses either the temperature or pressure of the steam and provides a representative type signal. Circuitry connected to the capacitance sensor and to the temperature or pressure sensor provides an output corresponding to the quality of steam in accordance with the capacitance and the temperature or pressure signal.

Appl. No.:

Inventors:

Donald J. Dowling - Houston TX
Jackie C. Sims - Houston TX

Assignee:

Texaco Inc. - White Plains NY

International Classification:

G01N 2135

US Classification:

250345

Abstract:

A steam quality monitor measures the quality of steam flowing in a steam pipe. A measurement cell is connected in the steam pipe so that steam flows through the measurement cell. The cell has two windows aligned along an axis which is traverse to the flow axis of the steam. A source spatially arranged with the windows of the measurement cells provides IR energy which enters the measurement cells through one window and leaves through the other window so that the IR energy passes through the steam flowing in the measurement cell. An IR detector detects the IR energy as it leaves the measurement cell and provides a corresponding signal. The temperature of the steam flowing through the measurement cell is also sensed and a temperature signal provided. Circuitry derives the steam quality of the steam flowing in the steam pipe in accordance with the signal from the IR detector and the temperature signal.

International Classification:

G01V 318
G01V 330

US Classification:

324338

Abstract:

The present invention is a well logging method for determining the water saturation of an earth formation and the water's resistivity. Electromagnetic energy is transmitted into the earthen formation from a borehole traversing the earth formation. The electromagnetic energy is transmitted at two different frequencies within a range of frequency from 10 MHz to 200 MHz. Electromagnetic energies are received in the borehole from the earth formation. A phase difference and amplitude ratio for each transmitting frequency is derived from the received electromagnetic energy. The water resistivity and water saturation of the earth formation are derived from the derived phase differences and the amplitude ratios.
