ABSTRACT:
A borehole cable includes a plurality of geophone-containing modules spaced apart along the cable by a plurality of conduit sections and designed for acoustic, thermal and pressure imaging of the subsurface. Each cable conduit section comprises an inner core of flexible tubing and an outer wall of interlock completely surrounding the core. The inner corrugated core is designed to compress under the external pressure applied by the formation in which it is deployed. The percent of core compression is controlled by adjusting the composition and structure of the inner core and the outer interlock wall. Compression of the inner core beyond a predetermined limit causes the interlock to form a rigid outer wall preventing further compression. The pressure at which the inner core begins to compress and the percent of compression at which the outer wall locks is determined by their material composition, wall thickness and pre-compression during manufacturing.
