| 20100039286 | Symbol Synchronization for Downhole OFDM Telemetry - Enhanced symbol synchronization methods suitable for use in narrowband orthogonal frequency division multiplexed (OFDM) telemetry systems. In at least some embodiments, a logging while drilling (LWD) tool assembly communicates with the surface using low frequency electromagnetic (EM) signals. The telemetry transmitter employs OFDM modulation to fully exploit the narrow range of available bandwidth, resulting in signals that have relatively long frames. At the surface a receiver digitizes the receive signal and applies an enhanced symbol synchronization technique to identify frame boundaries before demodulation is attempted. The enhanced symbol synchronization technique employs a pulse train filter to clean up a cyclic prefix correlation signal that otherwise behaves badly in the narrowband regime. The improved timing information from the enhanced symbol synchronization significantly reduces the error rate in the demodulated signal. | 02-18-2010 |
| 20100182161 | WIRELESS TELEMETRY REPEATER SYSTEMS AND METHODS - Various electromagnetic LWD telemetry systems are disclosed having a wireless repeater positioned on or near the seabed. The wireless repeater receives and demodulates electromagnetic uplink signals and retransmits the uplink signals from the seabed as electromagnetic or acoustic signals. A receiver on the drilling platform or suspended from the water's surface receives the uplink signal and forwards it to a facility for processing and storage. In some embodiments, the wireless repeater takes the form of a sub threaded inline with the drill string with an electromagnetic signal sensor positioned inside the drill string. In other embodiments, the wireless repeater takes the form of a unit that rests on the seabed with electromagnetic signal sensors inserted into the sea bottom. | 07-22-2010 |

At least some of the illustrative embodiments are methods including transmitting an acoustic signal comprising downhole data, receiving the acoustic signal (the receiving by a receiver disposed within the internal diameter of a casing in the wellbore) converting the acoustic signal to a corresponding first electromagnetic signal, and inducing a second electromagnetic signal in a tubing responsive to the first electromagnetic signal. | 07-07-2011 |
| 20120222900 | VIBRATION DETECTION IN A DRILL STRING BASED ON MULTI-POSITIONED SENSORS - In some example embodiments, a system includes a drill string having a drill bit. The drill string extends through at least part of a well bore. The system also includes a first vibrational sensor, positioned on the drill bit to measure, at a first location on the drill string, an amplitude of one or more of an axial vibration and a lateral vibration. The system also includes a second vibrational sensor, positioned above the drill bit and on the drill string. The second vibration sensor is to measure, at a second location on the drill string, one or more of an axial vibration and a lateral vibration. The system includes a processor unit to determine a type of vibration based on a comparison of the amplitude at the first location to the amplitude at the second location, wherein the type of vibration is at least one of bit whirl of the drill bit and a while of a bottom hole assembly that is part of the drill string. | 09-06-2012 |
