摘要： A method may include acquiring NMR data and sonic data for a borehole in a subsurface geologic region; inverting the NMR data and the sonic data to determine volume fractions for a number of classes of pore types, where the classes include shape and size-based classes; and characterizing the subsurface geologic region based on the volume fractions for the number of classes.

摘要： A method is provided for evaluating logging while drilling (LWD) nuclear magnetic resonance (NMR) measurement quality. The method may include rotating a bottom hole assembly (BHA) in a wellbore to drill. The BHA may include an NMR tool deployed at a first location and at least one motion sensor deployed at a second location, wherein the first and second locations are axially spaced apart in the BHA. The method may also include making NMR measurements and corresponding motion sensor measurements while drilling in the wellbore. The method may further include processing the motion sensor measurements to determine the NMR measurement quality of the corresponding NMR measurements.

摘要： Methods and systems are provided that employ a combination of dielectric dispersion measurement(s) and Nuclear Magnetic Resonance (NMR) measurement(s) to determine data that characterizes tortuosity of rock and data that characterizes tortuosity of fluid phases in the rock independently from one another.
