“…These were then used to calculate the amplitude index. This equation was used by several workers to determine the water and bitumen amounts in oil/water emulsion samples obtained from thermal production operations [72][73][74]. The same methodology was then applied to determine the oil and water fractions in oil sand cores and froths [23].…”

“…In co-operation with Canadian Natural Resources Limited (CNRL), a water cut meter utilizing low field NMR technology was operated on two different cyclic steam injection heavy oil well pads (22,23) . The only other recently published technology that tries to measure fluid production at thermal conditions is the nuclear fraction metering technology offered by Schlumberger.…”

This paper offers a summary of the advances in heavy oil and bitumen reservoir characterization and fluid stream monitoring using low field magnetic resonance tools. Both laboratory and field advances are presented. Although the bulk of the work discussed was performed in our laboratory, a selection of other pertinent technologies is also presented. This overview aims at offering the reader a quick reference of what has been achieved in the past ten years and it is hoped that it will be used as a guide for future development in this area.

“…The determination of in-situ fluid content in ore and froth samples follows essentially the same procedure as that developed for monitoring the water cut of heavy oil -water mixtures [21][22][23] . In essence, this procedure involves separating the signals of oil and water in a fluid mixture, and relating the individual fluid amplitudes to mass.…”

fax 01-972-952-9435. AbstractLow 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.A suite of real and synthetic samples of bitumen, water, clay and sand have been used to investigate the physical interactions of the different components on the NMR spectra. An automated algorithm is used to separate the oil and water NMR signals, and this algorithm is tested against samples both from this zone and from other heavy oil fields. Moreover, preliminary observations regarding spectral properties indicate that it may be possible in the future to estimate the amount of clay in the samples, based upon shifts in the NMR spectra. NMR estimates of oil and water content are fairly accurate, thus enhancing the possibility of using NMR for both in-situ oil sands development and in the oil sands mining industry.
