Abstract: The present invention provides a method and apparatus for acoustic position logging ahead of a drill bit. The method and apparatus comprise a bottomhole assembly (BHA) conveyed on a drilling tubular in a borehole within an earth formation. The BHA has a source array for emitting preselected acoustic signals into the earth formation, and at least one receiver on the BHA for receiving a second acoustic signal produced by an interaction of the preselected acoustic signal with said formation. The source array for acoustic energy may be configured as an axially distributed array of axially or azimuthally directed sources, or an azimuthally distributed array of axially or azimuthally directed sources. The sources may be activated according to preselected time delays. The emitted acoustic signal is differing in spectrum and/or wave mode from the acoustic energy of a rotating drill string.

Abstract: Downhole drilling characteristic measurement systems for measuring a characteristic of drilling through the earth's subsurface and methods of the same are described. The systems include a downhole tool having an active measurement system, comprising a receiver, a first transmitter, and a second transmitter and a controller in communication with the first transmitter and the second transmitter, the controller configured to control the first transmitter and the second transmitter to transmit a first transmitted signal from the first transmitter and a second transmitted signal from the second transmitter. The receiver is arranged to receive a first received signal from the first transmitted signal and a second received signal from the second transmitted signal. A processor is configured to determine a characteristic of drilling from the first received signal and the second received signal.

Abstract: A method for adjusting a parameter of a wellbore operation includes: conveying a carrier through the wellbore; performing a resistivity measurement on the formation using a resistivity tool disposed on the carrier; performing an acoustic measurement on the formation using an acoustic tool disposed on the carrier; generating with a at least one processor a map of the formation using the resistivity measurement and the acoustic measurement, and adjusting the parameter using the map.

Abstract: A downhole tool starts recording seismic energy. During the recording time, a surface seismic source is activated a specified number of times with a nominally defined separation between successive. The downhole sensor receives seismic waves resulting from the activation, but the time of the shooting sequence is not known downhole. The recorded data stream is processed and converted in real-time into seismic traces. A predefined number of traces are stacked and the quality of this sliding stack is used to detect time of the shooting sequence. The method could be used to detect one or several shooting sequences during a measurement window.

Abstract: A downhole acoustic logging tool is used for generating a guided borehole wave that propagates into the formation as a body wave, reflects from an interface and is converted back into a guided borehole wave. Guided borehole waves resulting from reflection of the body wave are used to image a reflector.

Abstract: Measurements are made continuously with a seismic while drilling (SWD) system and the measured data are stored in a working memory of a downhole processor along with quality control (QC) measurements. The QC data are analyzed and based on the analysis, portions of the data in working memory are recorded in permanent memory for retrieval. Alternatively, QC measurements are made substantially continuously predictions are made when data quality for SWD measurements are likely to be good. Recording of SWD data are then started based on the prediction.

Abstract: Acoustic measurements made in a borehole using a multipole source are used for imaging a near-borehole geological formation structure and determination of its orientation. The signal to noise ratio (as defined by the ratio of the signal radiated into the formation to the axially propagating signal) depends upon the type of source (force or volume) and its position in the borehole (on the tool, in the fluid or on the borehole wall).
