An empirical method, designated as DMR (density-magnetic resonance) porosity, combines density and nuclear magnetic resonance porosities to improve the estimate of tight gas sand porosity. The DMR ...

Well logging acquires in-situ measurements of rock and fluid properties along the wellbore to quantify reservoir quality, fluids, and well integrity. It underpins petrophysics, geomechanics, ...

SLB developed a multiwell automatic log correction (MALC) workflow which corrects neutron and gamma ray logs using machine learning (ML) to correlate regional and contextual references in historic log ...
