Filed:

Sep 23, 2002

Appl. No.:

10/148248

Inventors:

Gary Lee Scott - Sugar Land TX

Assignee:

PGS Onshore, Inc. - Houston TX

International Classification:

G01V 138

US Classification:

367 17

Abstract:

There is provided an apparatus and vehicle for laying seismic line cable on the ground, retrieving the cable from near the ground surface, and transporting the cable. The vehicle carries at least one cable reel for unspooling the cable therefrom when laying cable and spooling the cable thereon when retrieving the cable. When laying cable, a towed depression wheel forms a depression wheel forms a channel in the ground for laying the unspooled cable therein. The cable reel includes an electric slip ring for electrically energizing and testing the cable components while the cable is being laid. When used in very cold environments, a temperature controlled enclosure encloses the cable reel for maintaining the cable at a temperature at which it is sufficiently flexible for handling and laying. When retrieving cable, a motor power controller automatically controls the power to the cable reel drive motor for maintaining constant tension in the cable being retrieved. A cable tension measuring device provides feedback to the motor power controller.

Appl. No.:

09/347695

Inventors:

Gary L. Scott - Sugar Land TX

Assignee:

WesternGeco, LLC - Houston TX

International Classification:

G10K 1100

US Classification:

175 19, 181 05

Abstract:

An apparatus and method for orienting and for coupling geophones relative to soil. A hammer device oriented to the vertical drives a head into the soil to generate a case opening. Vertical orientation of the case opening and depth automatically orients a geophone case to vertical and further controls the coupling of the geophone to the soil. Such combination facilitates orientation of the geophone to the selected compass heading and significantly reduces corrective data processing. Control over case opening placement in different soil conditions is automatically provided, and data regarding local position and orientation is recorded for future data processing. Operator errors are reduced and overall production efficiency is enhanced.

Inventors:

Gary Lee Scott - Sugar Land TX, US

Assignee:

PGS Americas, Inc. - Houston TX

International Classification:

B66D 1/00

US Classification:

254277, 254278, 114254, 212309

Abstract:

A system or apparatus and method for retrieving cable from water during marine operations is provided that reduces damage to the cable from pulling forces during the retrieval. A pulling device distributes the forces and stresses all along the cable components. In one embodiment, the pulling drive comprises a pulling drum powered by a clutching system or by a hydraulic torque conversion system set to slip or stall at a selectable force value. The apparatus may use a see-saw action to maintain the forces below damaging levels. The system may be adapted for deploying cable in marine operations as well.

PGS Americas, Inc. - Houston TX

International Classification:

G01V 1/38

US Classification:

367 21, 367 20, 367 76, 367154

Abstract:

A seismic sensor cable is disclosed. The cable includes an outer jacket disposed on an exterior of the cable. The outer jacket excludes fluid from entering an interior of the cable. A reinforcing layer disposed within the outer jacket, which includes at least one electrical conductor disposed therein. An inner jacket is disposed within the reinforcing layer, and at least one electrical conductor disposed within an interior of the inner jacket. Some embodiments include at least one seismic sensor electrically coupled to the at least one electrical conductor disposed in the reinforcing layer In some embodiments a housing is disposed over the electrical coupling of the sensor to the conductor. The housing is molded from a polyurethane composition adapted to form a substantially interface-free bond with the cable jacket when the polyurethane cures.

International Classification:

G01V 1/28

US Classification:

Abstract:

Systems and methods are disclosed to construct subsurface images from diffuse seismic energy. Various disclosed system embodiments include multiple seismic sensors that each convert received seismic energy into one or more seismic signals. One or more processor combine the seismic signals to determine a subsurface map. As part of determining the map, the processor(s) systematically focus the array of seismic sensors on each bin in the subsurface volume of interest. In this manner each bin becomes a focal point of the array. For each bin, the processor(s) analyze the seismic wave travel time to each seismic sensor and apply a corresponding time shift to align the seismic signals with a uniform travel time. The time-shifted seismic signals are then combined to determine an intensity value for seismic energy radiating from the focal point. A subsurface map can then be derived from the intensity value as a function of position.
