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 ...

LWD acquires formation evaluation and wellbore data in real time while the bit is cutting rock. Sensors housed in drill collars measure gamma ray, resistivity, density, neutron porosity, sonic, NMR, ...

Dr. Roberto Volpe and his team at Queen Mary University of London and University College London in collaboration with the UK's national synchrotron, Diamond Light Source, have for the first time ...

A team of researchers from the Massachusetts Institute of Technology used Frontier to chart the isospin density of a neutron star over a range of conditions. This illustration depicts isospin-dense ...
