Abstract With the increase in production from shale oil and shale gas in North America during the last decade, many studies have been conducted in order to improve our knowledge from organic rich shale plays. Introduction After the commercial boom of unconventional reservoirs in North America during the past decade, exploration of unconventional shale reservoirs has increased significantly.
Samples and measurements Upper and lower members of the Bakken Formation are organic rich shales, and middle member is a mixture of carbonates and clastics. Well D cm-1 G cm-1 G-D cm-1 1 2 3 Well E GPa 1 2. Component Well 3 Well 5 Alginite 0. Results and discussion Systematic changes in band position, band separation, band full width at half maximum height for carbonaceous materials as a function of thermal maturity has been studied and well documented. Conclusion In this study, samples were taken from six wells in the Bakken Formation, Williston Basin.
Based on this study, following items can be concluded: Band separation of Raman major band signals can be used as maturity indicator. S1 from Rock-Eval was very well correlated with D band in Raman signal as an indicator of disorders in structure of organic matter molecule.
S2 from Rock-Eval also were correlated with G band in Raman signal as indicator of aromaticity of organic matter molecule. Acknowledgment The authors wish to thank Dr. References Abarghani, A.
