.... The most crucial step in this work is the grid refinement (x,y) to a meaningful value that is less than the DOD of planned UDAR configuration while preserving the vertical resolution (z). The grid refinement can either be local (around the wellbore) or regional. If the grid is refined from an already built...

A good match is shown with the total porosity calculated using density and neutron logs; however, the vertical resolution of NMR porosity is poorer than that of the conventional total porosity logs. This poorer vertical resolution is because the number of acquired NMR data...
