.... In contrast, drill cuttings are available for all the wells and thus can provide reservoir data throughout all the phases of the field development. A nuclear magnetic resonance (NMR) based method was developed to accurately determine petrophysical properties including porosity, bulk density, and matrix...

... ABSTRACT The process of mud-filtrate invasion gives indirect information about the dynamic petrophysical properties of reservoir rocks, which are essential to predict ultimate hydrocarbon recovery and to optimally design hydrocarbon recovery procedures. Our focus is on the interpretation...
