Abstract
Systems and methods include a computer-implemented method for determining relative productivity. A thorium-uranium ratio for a region of interest is determined by a diagenesis-calibrated rock quality (DCRQ) system using exploration and production (E&P) data. A percentage of siltstone in a lithology matrix for the region of interest is determined using the E&P data. A difference between a neutron porosity and a sandstone density porosity for the region of interest is determined using the E&P data. A rock testability index for the region of interest is determined. Relative productivity for the region of interest is determined using i) the thorium-uranium ratio, ii) the percentage of siltstone in the lithology matrix, iii) the difference between the neutron porosity and the sandstone density porosity, and iv) the rock testability index. Drilling parameters for use in upcoming drilling operations for wells in the region of interest are determined using the relative productivity.
