Development and Testing of a Drill Hole Instrument Placement System

摘要

From 1988 through 1990, the Office of Naval Research funded the Marine PhysicalLaboratory to conduct a pilot version of a wireline entry system. The system has been used at three northwestern Atlantic DSDP sites. The system is based on use of a standard 0.68 electromechanical cable and has the capability of carrying out location and simple reconnaissance logging of deep sea boreholes and for installation and telemetry involving more complex downhole payloads (e.g. an array of four three component geophones) from ships of the academic research fleet (e.g. KNORR, MELVILLE).
