Patent application numberDescriptionPublished
20100230113MULTI-STAGE MODULATOR - 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.09-16-2010

20100195442MUD PULSE TELEMETRY DATA MODULATION TECHNIQUE - A technique for communicating data within a wellbore is provided. In one embodiment, a method includes receiving digital data and encoding the digital data into symbols each representative of one or more data bits of the digital data In this embodiment, the method also includes modulating the phase of an acoustic wave within the wellbore to represent the plurality of symbols, wherein modulating the phase of an acoustic wave includes changing the phase of the acoustic wave such that the acoustic wave includes smooth phase transitions between successive phases representative of the plurality of symbols. Various additional methods, systems, and devices are also provided.08-05-2010

20090173493INTERFACE AND METHOD FOR TRANSMITTING INFORMATION TO AND FROM A DOWNHOLE TOOL - A downhole interface is disclosed that is positionable between a downhole tool, such as a wireline tool, and a wired drill string. The downhole tool communicates with the downhole interface which in turn communicates with the wired drill string to transmit information to the Earth's surface. The interface provides signal and power communication to the downhole tool.07-09-2009
