Title: Formation pressure measurement with remote sensors in cased hole
Inventor: CIGLENEC REINHART
IPC: E21B47/00
Filed: 1999-07-20
Granted: 2004-08-24
Abstract: The present invention relates to a method and apparatus for establishing communication in a cased wellbore with a data sensor that has been remotely deployed, prior to the installation of casing in the wellbore, into a subsurface formation penetrated by the wellbore. Communication is established by installing an antenna in an opening in the casing wall. The present invention further relates to a method and apparatus for creating the casing wall opening, and then inserting the antenna in the opening in sealed relation with the casing wall. A data receiver is inserted into the cased wellbore for communicating with the data sensor via the antenna to receive formation data signals sensed and transmitted by the data sensor. Preferably, the location of the data sensor in the subsurface formation is identified prior to the installation of the antenna, so that the opening in the casing can be created proximate the data sensor. The antenna can then be installed in the casing wall opening for optimum communication with the data sensor. It is also preferred that the data sensor be equipped with means for transmitting a signature signal, permitting the location of the data sensor to be identified by sensing the signature signal. The location of the data sensor is identified by first determining the depth of the data sensor, and then determining the azimuth of the data sensor relative to the wellbore.

Granted: 2003-04-01
Abstract: Rate detection of a data rate within a sequence of transmitted symbols employs correlation to calculate estimates of the auto-correlation values, or estimated coefficients, of the sequence. When the sequence of transmitted symbols includes repeated symbol values, the auto-correlation values indicate a degree of self similarity within the sequence. A decision statistic may be formed from the auto-correlation values. The self similarity of the auto-correlation values may be employed as a decision statistic with associated hypothesis test pair values.  Various decision methods may be implemented to compare auto-correlation values to thresholds based on the hypothesis test pair values. Based on the comparison, the data rate of the sequence may be determined. Once the information is determined related to the data rate, the information may be employed by a Viterbi detector to adjust the decoding rate for decoding the symbols.

Abstract: A bistatic coherent unlocked radar system (10) and processing method (30) using an advanced waveform (20) that permits bistatic unlocked coherent operation of an unlocked radar transmitter (11) and receiv er (12). The waveform (20) implements intrapulse fine range resolution, pulse to pulse coherency and burst to burst frequency agility to provide for enhanced target detection and robust operation in electronic countermeasure environments. A continuous sequence of pulses at different frequencies is transmitted (31) that may contain an acquisition frequency that is revisited more times than the other frequencie s. Energy reflected from a target is processed to detect (34) energy at the acquisition frequency, for example, over a plurality of range bins and predetermined pulse repetition intervals. A range pattern is generated (35) if the detected energy is above a predetermined threshold. The energy is centroided (36) to indicate the relative angle to the target. The transmitted frequencies contained in the pattern of energy a re identified (37). The receiver then frequency hops (38) with the transmitter. The energy is coherently processed using Fourier transforms to determine (39) the center in the pattern, which pattern is indicative of the direction to the target.
