Challenge: Improve the accuracy of reserves estimates in unconventional reservoirs where a traditional model for free plus adsorbed gas that is based on saturation methods and Langmuir isotherm assumptions is typically underestimating the gas volume.
Solution: Deploy new CMR-MagniPHI high-definition NMR service to acquire continuous T1T2 distributions that accurately map the distribution of porosity and fluids for a continuous evaluation of gas in place (GIP), independent of resistivity-based volumetrics and Langmuir isotherms.
Results: Improved reserves estimates, adding nearly 60 Bcf per section from accurate measurement of gas volume to enable better evaluation of the total GIP.
