Assignee:

Baker Hughes Incorporated - Houston TX

International Classification:

E21B 45/00

US Classification:

1662552, 16625011, 166 66

Abstract:

This invention provides a measurement-while-drilling (MWD) downhole assembly for use in drilling boreholes which utilizes directional formation evaluation devices on a rotating assembly in conjunction with toolface orientation sensors. The data from the toolface orientation sensors are analyzed by a processor and toolface angle measurements are determined at defined intervals. Formation evaluation sensors operate substantially independently of the toolface orientation sensors and measurements of the formation evaluation sensors are analyzed in combination with the determined toolface angle to obtain formation parameters.

International Classification:

G01V 3/12
H01Q 7/00

US Classification:

324333, 343866

Abstract:

A unified circuit without using a relay is proposed to resonate an antenna at more than two frequencies. The use of such analog IC switches are common place for transceiver applications in high RF frequencies (500 MHz and above). However, the use of selectively tuned antennas has for the most part been accomplished by the use of latching relays or fixed value components. The IC switch allows for not only the functionality of a single antenna to be either a transmitter and/or a receiver, but also allows, by adding additional switches to select any number of frequencies to resonate the antenna. This frequency resonation could be at fixed frequency points or sweep in either linear or logarithmic steps. The component selection of capacitors for either method would be controlled by a DSP or other microcontroller device. In one embodiment, an antenna for a downhole measurement tool is provided with a tuning circuit couple by a transformer to at least one antenna. The tuning circuit is disposed entirely within and protected by the hollow body of the tool and selectively tunes the antenna to at least three discrete frequencies. Advantageously, no structural modification is made on the outer surface of the tool to accommodate the tuning circuit. In one embodiment, a switching circuit enables a single antenna to function as both a transmitter and a receiver.

International Classification:

G01V 3/08

US Classification:

324338

Abstract:

An apparatus for estimating a property of an earth formation penetrated by a borehole, the apparatus having: a carrier configured to be conveyed through the borehole; a transmitter disposed at the carrier and configured to transmit electromagnetic energy at a first frequency into the formation; a first antenna disposed at the carrier and configured to receive electromagnetic signals from the formation as a result of the transmitted electromagnetic energy interacting with the formation; and an active filter coupled to the antenna and configured to filter electromagnetic signals received by the antenna to let the electromagnetic signals at the first frequency pass for processing to estimate the property.

International Classification:

G01V 3/00

US Classification:

3408533

Abstract:

The present disclosure includes an apparatus and method for operating a downhole tool in a borehole. The apparatus may include a downhole tool that may include at least one second clock, which may be synchronized to a first clock by way of a modulator/demodulator device. The downhole tool may be configured to estimate a parameter of interest of an underground feature. The underground feature may relate to one or more of: a borehole, a casing, or an earth formation. The downhole tool may comprise two or more sections that are configured to operate synchronously when the one or more second clocks are synchronized with the first clock. The modulator/demodulator may include a modem associated with the first clock, a modem associated with the at least one second clock, and a low frequency conductor between the two modems. The method includes using the apparatus.
