    摘要: A method for obtaining a parameter of interest relating to a region investigated by a nuclear magnetic resonance (NMR) tool and a non-NMR tool is disclosed. Data arising from the NMR tool is acquired, and data arising from the non-NMR tool is acquired. A solution equation is utilized for NMR signal intensity, the solution equation being functionally related to the NMR data, and a solution constraint is utilized based at least partially on the non-NMR data. The solution equation is solved for the signal intensity subject to the solution constraint, wherein the solving provides information relating to the parameter of interest.
