6 June 2018 – Amjed Hassan, a PhD student at KFUPM and winner of the 2017 SPWLA SAC / SPWLA-KFUPM Chapter Student contest, presented his research paper “Determination of Water Saturation Distribution for Complex Reservoirs” at the 59th SPWLA Annual Symposium Student Paper Contest in London, UK. Amjed’s research work includes development of a new mathematical tool and methodology for determining the water saturations in complex reservoirs. The developed model is targeted to determine water saturation for dual and triple porosity system utilizing NMR and other logging data. NMR measurements are used to obtain the volume fraction of each pore network, then, water saturation is determined using the resistivity and porosity logs. This study demonstrates that the developed models proffer petrophysicists more flexibility to capture the impacts of pore structure in evaluating complex formations.
