The upsampling mechanism takes the derivative of the discrete-time input sample stream, thereby effectively providing another order of interpolation over a conventional interpolator. Before outputting the interpolated signal, an integrator takes the integral of the interpolated samples. Any processing performed between the derivative and integrator blocks effectively provides an additional order of interpolation. High frequency noise (i.e. dithering) is added to the differentiated samples in order to eliminate the spectral regrowth spurs that would otherwise appear in the output after rounding. Delay alignment is performed on the differentiated samples in order to time align both phase/frequency and amplitude samples that are processed on different paths. | 06-03-2010 |

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. | 10-22-2009 |
| 20100230113 | MULTI-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 |
| 20100236777 | POWER SYSTEMS FOR WIRELINE WELL SERVICE USING WIRED PIPE STRING - A wellbore instrument system includes a pipe string extending from earth's surface to a selected depth in a wellbore. The pipe string includes at least one of an electrical conductor and an optical fiber signal channel. A power sub including an electric power source is coupled proximate a lower end of the pipe string. At least one electrically powered wireline configurable wellbore instrument is coupled to the power source in the sub. | 09-23-2010 |
| 20100307828 | SYSTEMS AND METHODS FOR CANCELING NOISE AND/OR ECHOES IN BOREHOLE COMMUNICATION - 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. | 12-09-2010 |
| 20110031015 | SYSTEM AND METHOD FOR MANAGING AND/OR USING DATA FOR TOOLS IN A WELLBORE - A system and a method manage and use data related to a wellbore or a drill string. The system and the method may provide remote access to tools in a drill string using a network. In addition, the tools have access to the data. In a disclosed embodiment, the tools are able to automatically access the data needed to optimize or improve function of the tools. An example of the network is a wireless network where the tools may be monitored and/or controlled remotely by an application. A linking tool is optionally provided to communicate with the network and one or more of the tools. | 02-10-2011 |
| 20110042072 | METHOD AND SYSTEM FOR USING WIRELINE CONFIGURABLE WELLBORE INSTRUMENTS WITH A WIRED PIPE STRING - A wellbore instrument system includes a pipe string extending from earth's surface into a wellbore. At least a portion of the pipe string includes a signal communication channel having a cable, such as an electrical conductor or an optical fiber. At least one wireline configurable wellbore instrument is coupled to the pipe string and has at least one sensor therein for measuring a physical parameter. The at least one instrument is in signal communication with the signal communication channel in the pipe string. The system includes a controller functionally associated with the at least one instrument and configured to initiate operation of the at least one sensor upon detection of a command signal. | 02-24-2011 |
