Abstract
A method of deconvolving the far-spaced detector response of a dual-spaced neutron logging tool, coupled with dynamic matching of the near-spaced detector response, improves the vertical resolution of the tool's formation porosity measurements. Near/far ratio processing and the standard shop calibration procedure are retained to continue to provide accurate, borehole compensated formation porosity measurements.
