IMPROVEMENTS IN OR RELATING TO GEOLOGICAL LOGGING

摘要

A method of improving geological log data comprises the steps of: (i) moving a drillpipe-conveyed logging tool in a borehole in a formation while operating the logging tool to obtain log data of a first category; (ii) periodically halting the logging tool supported by the drillpipe; (iii) while the logging tool is halted, obtaining log data of at least a second category; and (iv) processing or storing the log data of the second category and/or using the log data of the second category to improve the quality of the data of the first category and/or combining the data of the first and second categories.
