ABSTRACT:
A seismic array system for receiving seismic signals at spaced-apart points in a wellbore is deployable on coiled tubing from the surface through an isolator apparatus mounted on the wellhead. The array includes spaced-apart geophone sondes which have hydraulic actuators for extension of sonde support pads into engagement with the wellbore wall. Each sonde has a hydraulic control unit for controlling operation of the hydraulic actuator to extend or retract the pads and for preliminary processing of signals received through the geophones of each sonde. Hydraulic fluid and electrical control signals are communicated through the coiled tubing from the surface. A signal processing unit is deployed at the upper end of the array string for final or intermediate processing of the geophoen signals from each sonde.
