Abstract

This paper describes a feasibility study, sponsored by the Offshore Supplies Office of the UK Department of Energy, to establish a new calibration scale for neutron porosity tools in sandstone formations. It includes the results of novel materials characterisation studies and detailed Monte Carlo predictions of porosity tool performance in the SPARTAN Test Pits comprising three formations of artificial sandstone and one of natural sandstone.
