ABSTRACT:
A coal bed anomaly detection and imaging system comprises a synchronous transmitter and receiver that are separated by a geologic structure with embedded and hidden anomalies. The receiver is housed in a shuttle body that can be pumped into a borehole by water or air pressure. The shuttle may itself employ hydraulic inching mechanism to move within the drillhole. Signal measurements are reported out over a fiberoptic pigtail. A separate radio signal path provides synchronization between the transmitter and receiver. The receiver shuttle is tethered by this fiberoptic pigtail, and it can be withdrawn from the borehole by the tether.
