2007 04 17 Capillary Pressure Curves obtained using new Magnetic Resonance Imaging TechniquesTuesday, April 17, 2007 EnCana Amphitheatre, 2nd Floor Tower Centre InvitationGreen Imaging Technologies, PTAC Petroleum Technology Alliance Canada, and co-sponsor Corelab invites you to attend an information session focused on a MRI based Capillary Pressure Testing Technique to learn more about this patented technology and the market validation trials taking place in advance of the 2007 introduction of this new faster and more accurate testing technique. This presentation will provide an overview of the underlying MRI technology, a brief description of the patented technique for finding capillary pressure, and a summary of results of a comparison trial conducted during the winter of 2006 and 2007. The comparison trial evaluated the new test by comparing capillary pressure curves produced through the traditional multi-speed centrifuge method and the new MRI-based measurement technique. BACKGROUNDTraditional centrifuge capillary pressure measurements require the fluid(s) to reach equilibrium at many different speeds. This is very time consuming as each equilibrium step can take days. A new method, called GIT-CAP, centrifuges the core plugs at a single speed then directly measures the water saturation distribution in the core plug using magnetic resonance imaging. The measured water saturation together with the known centrifugal force directly leads to a capillary pressure curve. The new technique measures the capillary pressure curve more quickly and accurately. The new method is an order of magnitude faster due to fact only one or two centrifuge speeds are required (versus 7-10). In some rock types this reduces the measurement duration from many weeks to days. The new technique is also potentially more accurate as it directly measures the water saturation in the rock instead of relying on a calculation using a measurement of the expelled water. PROJECT/TECHNOLOGY DESCRIPTIONThe Market Validation trials are being performed in 2 phases. Phase 1 began in 2006 at the University of New Brunswick using a quantity of old cores that had been previously tested. Cores were donated by a number of organizations including Chevron and Shell. Phase 2 of the market validation began in Houston with a prototype installed at Corelab. This phase consisted of simultaneous testing of "live" cores using both the old and new techniques. The objectives of both tests were to compare results from both a speed and accuracy perspective. The trials are slated to continue in 2007 for as long as it takes to create an accurate field of results and confidence in the technologies breakthrough value. At the moment we project the product to be available commercially in the second quarter of 2007. Early benefits are consistent with higher quality capillary curve data which in turn provides a better description of the reservoir. This is an information session where participants are welcome to offer observations and questions which they feel would need to be answered prior to our commercial launch. WHO SHOULD ATTENDTarget audience should be core testing labs especially those doing capillary pressure testing, Reservoir analysts, NMR/MRI specialists with an interest in the industrial solutions of this technology.
