US Patent:

Filed:

Jul 25, 2006

Appl. No.:

11/492233

Inventors:

Christopher J. Powell - Houston TX, US
Louis Perez, Jr. - Houston TX, US

Assignee:

Baker Hughes Incorporated - Houston TX

International Classification:

E21B 49/08

US Classification:

16625001, 7315218, 324324

Abstract:

A method and apparatus are provided for insulating electrical connections to a resonator from fluid downhole under extreme pressure and temperature conditions downhole. The method and apparatus provide a pliable insulator that maintains electrical isolation between resonator electrical connections during exposure to high pressures downhole. The insulator is evacuated or placed in a vacuum prior to curing to remove bubbles from the insulator material. The insulator is then heat cured. The insulator is substantially chemically non reactive so that the insulator maintains electrical isolation between the resonator electrical connections during exposure to fluids downhole. The insulator has a thermal coefficient of expansion in a range so that the insulator maintains electrical isolation between the resonator electrical connections during exposure to high temperatures downhole.

International Classification:

G01S 15/00

US Classification:

367 89

Abstract:

Pairs of acoustic transducers positioned at different radial distances in a conduit are used to measure travel times of acoustic signals in opposite directions and inclined to the direction of a fluid flow in the borehole. These contrapropagation measurements are used to estimate fluid velocity and volumetric flow rates of the fluid components in the conduit.

Abstract:

Embodiments of the invention provide an untethered apparatus for measuring properties along a subterranean well. According to at least one embodiment, the untethered apparatus includes a housing, and one or more sensors configured to measure data along the subterranean well. The data includes one or more physical, chemical, geological or structural properties in the subterranean well. The untethered apparatus further includes a processor configured to control the one or more sensors measuring the data and to store the measured data, and a transmitter configured to transmit the measured data to a receiver arranged external to the subterranean well. Further, the untethered appratus includes a controller configured to control the buoyancy or the drag of the untethered apparatus to control a position of the untethered apparatus in the subterranean well. The processor includes instructions defining measurement parameters for the one or more sensors of the untethered apparatus within the subterranean well.
