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 ...

Wireline logging in exploration acquires high-resolution downhole measurements in open hole to determine rock and fluid properties, confirm hydrocarbons, quantify volumes, and guide immediate well ...

This early journaling system has evolved to encompass lowering logging tools into the wellbore via wireline in order to measure porosity, resistivity, permeability, temperature, water saturation and ...

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 ...
