WELL LOGGING WITH REDUCED USAGE OF RADIOISOTOPIC SOURCES

机译:减少放射性同位素源的测井

摘要

Logging systems and methods are disclosed to reduce usage of radioisotopicsources. Some embodiments comprise collecting at least one output log of atraining well bore from measurements with a radioisotopic source; collectingat least one input log of the training well bore from measurements by a non-radioisotopic logging tool; training a neural network to predict the outputlog from the at least one input log; collecting at least one input log of adevelopment well bore from measurements by the non-radioisotopic logging tool;and processing the at least one input log of the development well bore tosynthesize at least one output log of the development well bore. The outputlogs may include formation density and neutron porosity logs.
