Abstract

A superconducting quantum interference device (SQUID) magnetic detection apparatus detects magnetic fields, signals, and anomalies at remote locations. Two remotely rotatable SQUID gradiometers may be housed in a cryogenic environment to search for and locate unambiguously magnetic anomalies. The SQUID magnetic detection apparatus can be used to determine the azimuth of a hydrofracture by first flooding the hydrofracture with a ferrofluid to create an artificial magnetic anomaly therein.

Method and apparatus for balancing the magnetic field detecting loops of a cryogenic gradiometer using trimming coils and superconducting disks

Patent Lutes, C.L.

An apparatus for and a method of measuring the difference in intensity between two coplanar magnetic field vector components at two different points in space. The device is comprised of two interconnected, relatively large, loop patterns of opposite, flux cancelling, winding sense. One or both loops include a trimming element that is itself formed of two interconnected, relatively small, loop patterns of opposite, flux cancelling, winding sense. The device is analyzed for imbalance between the two large loops and is then balanced by placing a balancing superconducting disk of the proper characteristic in or near one of the two smallmore »« less
Detection of a thin sheet magnetic anomaly by squid-gradiometer systems: possibility of hydrofracture azimuth determination

Conference Overton, W.C. Jr.

A study of the signal physics of magnetic anomaly detection was carried out by superconducting gradiometer and magnetometer loop systems with SQUID sensors for possible application to the LASL geothermal energy program. In particular, the crack produced by hydrofracture of a deep HDR geothermal borehole would be filled with a magnetic material such as ferrofluid. When polarized by the earth's field, this material would produce a localized crack magnetic anomaly which is characteristic of the azimuth of the vertical crack with respect to magnetic north. Signatures of the anomaly would be determined by taking rotation data before and after fillingmore »« less

Feasibility of detecting artificial magnetic anomalies in hydrofractured rock by super-conducting gradiometer-SQUID systems

Book Overton, W.C. Jr.

A study of the signal physics of magnetic anomaly detection by superconducting gradiometer-SQUID systems to determine the feasibility of possible applications to the geothermal energy program is described. The system would make full use of the incredible sensitivity of the superconducting quantum interference device (SQUID) which can be in the range of 10/sup 11/ Oe. In addition to magnetic anomalies in the earth's field produced by spherical distributions of magnetic matter, anomalies that would be artificially produced by flooding magnetic material into cracks produced by hydrofracturing in deep boreholes drilled into dry rock geothermal sources are considered. The study indicatesmore »« less
