Abstract

An experimental skid-type pulsed nuclear magnetic resonance logging tool (PNMT) has been evaluated in Shell’s Johnson City test well. The tool shows considerable promise for logging producible fluid, porosity and permeability. The skid-type design has excellent vertical resolution, eliminates doping the borehole mud with magnetite and is also unaffected by the salinity of the mud.
