The DHA-7 downhole hydrophone array is designed for high-resolution seismic borehole
imaging. Unique proprietary polymer hydrophones (no ceramics) are in-line molded to a fully integrated,
triple-sealed multi-conductor cable. Non-shattering polymer material provides superior
performance and durability under the rigors of borehole applications and a stable signal response
up to 10 kHz.
The Model DHA-7 is suited for use in cased and uncased, water-filled, narrow-diameter boreholes.
The standard configurations include a group interval of 0.5 to 5 m and a total cable length
of up to 400 m (1,312 ft). The cable is terminated topside with suitable connectors to mate with
the seismograph and a 12VDC rechargeable power supply. Custom group intervals and multiborehole
configurations are also available to tailor the system to meet your needs. The array is
easily deployed by hand.
