Description

Direct petrophysical measurements, such as density and magnetic susceptibility, may prove useful in improving the interpretability of geophysical models. With measurements becoming more abundant and the capability to measure petrophysical properties across the entirety of drill core, there is a need to explore to what extent such measurements may enhance or improve physical property models derived from geophysical inversion. Towards that goal, we seek to explore and develop a workflow for using petrophysical data in 3D potential field inversion. The Stavely Arc region is selected as a study area where drill core petrophysics and regional potential-field data are available. We apply 3D gravity inversion to a subset of the region and use the available density measurements as constraints in the inversion. Results indicate that using petrophysical measurements in inversion may help to further constrain the recovered physical property values in areas away from the borehole locations.
