- [Gary A. Simpson] So finally a summary. We integrated advanced downhole logging measurements and resulted in defining robust Petrophysics Models for the Bakken Petroleum System. Model results were compared to numerous core analyzes and increased confidence in the petrophysics models. The NMR and dielectric measurements revealed deficiencies in core analysis techniques and methods used for unconventional tight oil. The one thing I didn't mention is that when we found this problem, three of the cores that we had cut in the Bakken Petroleum System, we stopped all analysis on it, and we are just now getting back with new protocols and all that we had finally researched, to start analysis on three of those cores. So the methods for estimating producibility are possible, but understand that each of the Bakken Petroleum System reservoirs has its own distinct set of characteristics that must be recognized and leveraged when evaluating their productive potential. The Basin-wide Petrophysics Models that we used as a reduced logging sets are currently under development, and we're using the Data Wells with advanced logging suites to help help develop and calibrate these interpretation techniques for the basin-wide model. And lastly, results from the Petrophysics Model provides the basis for re-calculating the Stock Tank Oil Initially in Place, STOOIP, refining production type curves, and characterizing the Bakken Petroleum System across the basin and improving agreement with measured production results. The authors would like to thank the Hess Corporation and the Bakken Asset Team for granting us permission to publish and present this manuscript. We would also like to thank Schlumberger for committing their resources to producing the manuscript.
