Advances in Oil and Water Saturation Measurements Using Low Field NMR

摘要

Low field nuclear magnetic resonance(NMR)relaxometry has been successfully used in the past to perform in-situ estimates of oil and water content in unconsolidated oil sand samples. This work has intriguiging applications in the oil sands mining and processing industry,in the areas of ore and froth characterization.Studies have previously been performed on a database of ore and froth samples from the Athabasca region in northern Alberta,and preliminary results have been encouraging.In this paper,supporting data is presented and refinements suggested to the previous algorithms,to improve the oil and water saturation predictions.
