摘要： NMR spin echo signals are acquired downhole. Principal Component Analysis is used to represent the signals by a weighted combination of the principal components and these weights are telemetered to the surface. At the surface, the NMR spin echo signals are recovered and inverted to give formation properties. Real-time displays may be used for determining formation properties and for altering the acquisition parameters.

摘要： Data from a string of multiple formation evaluation data sensor (14) are evaluated by an expert system Based on the analysis, the logging speed is increased if all the sensors (12, 14, 16, 18) justify it, and is reduced if any of the sensors (12, 14, 16, 18) require a reduced logging speed. Alternatively, the sensitve volume of a NMR sensor (305) is altered based on a determination of a fraction of the sensitive volume that includes a borehole fluid.
