Abstract: The present disclosure provides a method and system for supplemental processing of recorded historical data in real time to fill in gaps of lost data. A user who may be monitoring the data from human interfaces can immediately recognize an issue, quickly change one or more settings for parameters (including changing one or more of the parameters), and replay for reprocessing the recorded data to provide a revised output that can catch up to the processing of later current data without needing to halt operations. In at least one field of use, the invention can eliminate the need for restarting a complete drilling process to resynchronize the surface system when the system is not able to demodulate a valid bitstream, saving time and maintaining high drilling efficiency.

Abstract: Methods and systems for pulse generation assembly that includes a plurality of staged valves operably coupled serially in a bottomhole assembly of a wellbore tool. The plurality of staged valves are operated in a substantially synchronized manner, thereby generating a series of pressure pulses. The signal strength of the generated pulse signal is multiplied by the number of staged valves in the series, and the pulse generation assembly of the disclosure is less susceptible to jamming, shock, and erosion. Further, by sequentially stopping at least one stage of the assembly and then synchronously rotating other stages, amplitude modulation is accomplished.

Abstract: Systems and methods cancel or compensate for an echo or noise in borehole communication. The systems and methods provide a downhole tool configured to provide borehole communication via mud pulse telemetry. The downhole tool pulses drilling fluid to generate a first pressure pulse and a second pressure pulse. The first pressure pulse moves upwardly with respect to the downhole component and is encoded with data associated a downhole measurement. A sensor is electrically connected to and in communication with the downhole tool. The first sensor is adapted to detect a characteristic of the second pressure pulse in the drilling mud. A ideal pressure pulse or a correction pressure pulse is generated by a downhole tool or a mud pulse modulator to reduce or cancel noise of the second pressure pulse.

Abstract: A system and method for communicating with a downhole tool is disclosed. In one embodiment, a telemetry system for communicating with a downhole tool in a wellbore includes a first electrode. A modulated electric current flows from the first electrode through a formation to the downhole tool. The telemetry system also includes a downlink box, which provides the modulated electric current to the first electrode. The downhole tool comprises a sensor unit, which detects the modulated electric current. The telemetry system includes a second electrode that allows the modulated electric current to return to the downlink box. The telemetry system also includes an uplink telemetry, wherein the uplink telemetry does not comprise electromagnetic telemetry. In some embodiments, the downlink may be operated while mud pumps are turned off. The downlink may also be operated while the downhole tool is sending uplink telemetry by a method other than electromagnetic current.

Abstract: Example wellbore telemetry systems and methods for transmitting signals between a surface unit and a downhole tool are disclosed. One example method transmits data between a downhole location in a wellbore and a surface location associated with the wellbore by measuring downhole data via at least one downhole component and generating a data frame containing at least a portion of the downhole data. The example method varies a telemetry bandwidth allocated to the at least one downhole component in response to the at least some of the downhole data corresponding to a special event and transmits the at least some of the downhole data to the surface location via the telemetry bandwidth allocated to the at least one downhole component.

Abstract: An apparatus for sorting articles based upon the presence of defects on the surface thereof is characterized by a roller conveyor carrying a random array of articles in transverse channels defined between adjacent rollers. As the conveyor is advanced through a viewed area the articles are simultaneously rotated such that electrical images are formed of the portions of the surface of each article within a viewing zone defined in each channel during a given time frame. The viewing zones advance a predetermined distance through the viewed are in synchronization with the scanning of the electrical images. A characteristic signal for the portion of the electrical image corresponding to each article is developed and output to a processor. The processor generates a classification signal representative of the acceptability of each article based upon the percentage of total surface of area or number of defects on the surface each article.
