Seismic Skinny HTI hydrophone string for downhole seismic
This new, slender hydrophone string is just the ticket for collecting seismic data in a narrow borehole. With a maximum outside dimension of only 1.25", the cable will easily fit into any 2" ID borehole. The cable is outfitted with (12) HTI-96 hydrophones (unamplified) at 3 foot intervals and has a 250 foot lead terminated with a Geometrics-type Bendix 61 connector at one end and a small stainless stress anchor at the other.
