US Patent:

52392678, Aug 24, 1993

Filed:

May 15, 1991

Appl. No.:

7/700275

Inventors:

Roland E. Chemali - Austin TX
Joseph F. Goetz - Katy TX

Assignee:

Halliburton Logging Services, Inc. - Houston TX

International Classification:

G01V 334
G01V 338
G01V 318
G01V 300

US Classification:

324376

Abstract:

The present system is directed to an improved dipmeter system including plural sensors on isolated pads around a sonde. An independent output is formed from each of the sensor pads, and each output is provided to its own adjustable high pass filter. The several high pass filters delete low frequency constituents in the sensor signals. Then, the signals are provided to a dipmeter computer to determine depth with greater accuracy. As a variation, the high pass filters can be selectively adjusted to provide an adjustable frequency for the filters, and one version utilizes the derivative of the dipmeter signal as a function of velocity or time.

Appl. No.:

8/584227

Inventors:

James F. Brett - Tulsa OK
Joseph F. Goetz - Tulsa OK
Alan P. Roberts - Bixby OK

Assignee:

Oil & Gas Consultants International, Inc. - Tulsa OK

International Classification:

E21B 4325

US Classification:

166249

Abstract:

Methods are provided for making use of an apparatus for generating vibrational energy in a borehole, the apparatus utilizes a mass and a rotary source for suspending the mass in a borehole or in casing in a borehole or in an instrument housing that may be positioned in an opened or cased borehole arranged to cause frictional contact with the surface of the rotating mass, the mass being rotatable about is rotational axis in one direction to cause it to backward whirl in the opposite direction, the centrifugal force of the whirling mass serving to generate vibrational energy that is used to obtain geophysical information as to the structure of the earth surrounding and adjacent to the borehole and for enhancing cementing and production enhancing techniques in oil or gas wells.
