Abstract
A method for determining the solids content, fines content and/or particle size distribution of the solids in an oil sands process stream test sample comprising bitumen, solids and water using low-field time-domain NMR is provided which involves building a non-solids partial least squares calibration model using oil sands process streams calibration samples having a known bitumen content, solids content, water content, fines content and/or particle size distribution by subjecting the calibration samples to a first T1-weighted T2 measurement NMR pulse sequence that maximizes very fast relaxing signals and a second T1-weighted T2 measurement NMR pulse sequence that maximizes slow relaxing signals. The measurement of other sample properties strongly correlated with surface area, such as methylene blue index, can also be measured using a partial least squares calibration model.
