"AUTOMATIC ADJUSTMENT OF NMR PULSE SEQUENCE TO OPTIMIZE SNR BASED ON REAL TIME ANALYSIS"
Application 5850/DELNP/2006 published 2007-07-13, filed 2006-10-09
Data from a string of multiple formation evaluation data sensor are evaluated by an expert system. Based on the analysis, the logging speed is increased if all the sensors justify it, and is reduced if any of the sensors require a reduced logging speed. Alternatively, the sensitive volume of a NMR sensor is altered based on a determination of a fraction of the sensitive volume that includes a borehole fluid.
