Triaxial Thermopile Array Geo-Heat-Flow Sensor

View page
US Patent:
51219930, Jun 16, 1992
Filed:
Apr 30, 1990
Appl. No.:
7/516399
Inventors:
Charles R. Carrigan - Tracy CA
Harry C. Hardee - Albuquerque NM
Gerald D. Reynolds - Tijeras NM
Terry D. Steinfort - Tijeras NM
Assignee:
The United States of America as represented by the Department of Energy - Washington DC
International Classification:
G01K 1300
G01N 2520
US Classification:
374 29
Abstract:
A triaxial thermopile array geothermal heat flow sensor is designed to measure heat flow in three dimensions in a reconstituted or unperturbed subsurface regime. Heat flow can be measured in conductive or permeable convective media. The sensor may be encased in protective pvc tubing and includes a plurality of thermistors and an array of heat flow transducers arranged in a vertical string. The transducers produce voltage proportional to heat flux along the subsurface regime and permit direct measurement of heat flow in the subsurface regime. The presence of the thermistor array permits a comparison to be made between the heat flow estimates obtained from the transducers and heat flow calculated using temperature differences and Fourier's Law. The device is extremely sensitive with an accuracy of less than 0. 1 Heat Flow Units (HFU) and may be used for long term readings.

Apparatus And Method For Monitoring Underground Fracturing

US Patent:
59343737, Aug 10, 1999
Filed:
Jan 29, 1997
Appl. No.:
8/790292
Inventors:
Norman R. Warpinski - Albuquerque NM
Terry D. Steinfort - Tijeras NM
Paul T. Branagan - Las Vegas NV
Roy H. Wilmer - Las Vegas NV
Assignee:
Gas Research Institute - Chicago IL
International Classification:
E21B 4700
US Classification:
1662501
Abstract:
An apparatus and method for measuring deformation of a rock mass around the vicinity of a fracture, commonly induced by hydraulic fracturing is provided. To this end, a well is drilled offset from the proposed fracture region, if no existing well is present. Once the well is formed to a depth approximately equal or exceeding the depth of the proposed fracture, a plurality of inclinometers, for example tiltmeters, are inserted downhole in the well. The inclinometers are located both above and below the approximate depth of the proposed fracture. The plurality of inclinometers may be arranged on a wireline that may be retrieved from the downhole portion of the well and used again or, alternatively, the inclinometers may be cemented in place. In either event, the inclinometers are used to measure the deformation of the rock around the induced fracture.
