Title: Fishing tool retrieves MWD nuclear source from deep well

Journal Article · · Oil and Gas Journal; (United States)
OSTI ID:5562393

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 and 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[degree]. The paper briefly describes the operation and equipment.
