Abstract: A downhole seismic exploration device comprises a seismic detector such as a geophone and a magnetic clamp, supported by O-rings (45, 46) in an open cradle carrier (39) which can be secured to a cable (64) linking several such devices into an array. The array is lowered into a cased borehole and the magnetic clamps (51, 52) are operated to clamp the devices temporarily to the casing. Seismic signals detected by the geophones are transmitted to the surface via the cable (64), the O-ring supports (45, 46) acting to reduce or eliminate transmission of vibrations from the borehole fluid and the cable (64) via the carrier (39) to the geophone (44). The array is then unclamped and moved to another location in the borehole and the operation repeated. The magnetic clamp comprises a rotatable permanent magnet with radial poles disposed between a pair of parallel pole piece plates protruding on each side of the device and separated by non-magnetic blocks on each side of the magnet. When the magnet poles are aligned parallel to the pole piece plates the magnetic flux extends along closed paths entirely within the pole pieces and there is no clamping action. When the magnet is rotated 90° by a small motor the magnetic flux extends along the pole pieces and out of the device, clamping the device by magnetic attraction to the casing. A piezo bimorph element can be operated to vibrate the device to test the quality of the clamping before the acquisition of seismic data.

Abstract: Methods and systems utilizing seismic sensors configured or designed for use in seismic signal detection are provided so as to reduce the occurrence of spurious responses of the sensors. A method of seismic surveying using a seismic sensor may include the steps of deploying the seismic sensor at a location for seismic signal detection and acquiring seismic signals. The seismic signals may include high frequency response signals containing spurious response signals at an identifiable bandwith. The method may further include applying spurious cancellation based on the bandwith location of the spurious response signals and generating modified seismic waveforms having extended frequency bandwidth.
