International Classification:

G01V 3/18

US Classification:

324324, 324369, 324338

Abstract:

Transducer apparatus for subsurface use. A tubular configured for subsurface disposal is equipped with a cylindrical transducer module formed of a non-conductive material. The module is mounted to surround a section of the tubular and includes a transducer element disposed thereon such that only a surface of the element is exposed along the exterior of the module body. The transducer element is linked to a lead routed through the cylindrical body to exit near the inner bore of the body. The ends of the cylindrical body are covered with a material to form a hydraulic seal. A method for constructing the transducer apparatus.

International Classification:

G01V 3/18

US Classification:

324324, 324369, 324338

Abstract:

A logging sonde includes a tube defining a sealed chamber inside. An isolation layer is disposed on an exterior of the tube. At least one sensor is disposed on an exterior of the isolation layer. The sensor includes a lead in passing through a wall of the tube. An elastomer jacket is disposed on an exterior of the sensor and the isolation layer. A method for making a sonde includes affixing an electrically insulating isolator to an exterior of a tube. An hydraulic seal layer is affixed over an exterior of the isolator. A sensor is affixed over the exterior of the seal layer. An electrical connection is made from the sensor to an interior of the tube through the hydraulic seal layer and through the isolator. An elastomer jacket is applied over the exterior of at least part of the sensor and the exterior of the seal layer.

International Classification:

G01R 35/00

US Classification:

324202

Abstract:

An electromagnetic logging tool is disclosed that includes a support; and at least one four-coil array disposed on the support, wherein the at least one four-coil array comprises: a transmitter, a bucking coil, a receiver, and a trim coil. A method for balancing an induction array is disclosed that includes applying an alternating current to a transmitter of the induction array that comprises the transmitter, a bucking coil and a receiver; measuring a mutual coupling between the transmitter and the receiver; and adding an extra bucking coil, if the mutual coupling exceeds a selected criterion.
