FISHING TOOL RETRIEVES MWD NUCLEAR SOURCE FROM DEEP WELL

A new wire line tool has successfully retrieved the nuclear sources and formation data from a measurement while drilling (MWD) tool stuck, in a deep, highly deviated well in the Gulf of Mexico. On Nov. 8, 1993, Schlumberger Wireline & Testing and Anadrill ran a logging-while drilling inductive coupling (LINC) tool on conventional wire line to fish the gamma ray and neutron sources from a compensated density, neutron (CDN) tool stuck in a well at 19,855 ft with an inclination greater than 80.
