The Kevin Dome is a large anticlinal structure within the Rocky Mountain foreland east of the Lewis thrust front in north-central Montana, USA. The dome was initially chosen as a test site for the U.S. Department of Energy Regional Carbon Sequestration Partnership program, in part, because of the availability of a significant natural accumulation of carbon dioxide that could be extracted and re-injected into another part of the structure to test the viability of long-term geologic carbon storage in domal structures of the Rocky Mountain foreland. However, due to regulatory restrictions, the project was re-scoped to maximize learnings from the rock cores.
The primary natural CO2 reservoir and carbon storage target occurs within the middle part of the Devonian Duperow formation. The Duperow is a shallow marine carbonate and evaporite unit comprising, in order of decreasing abundance, dolostone, limestone, and anhydrite lithologies. Different primary depositional facies have been recognized in the Duperow corresponding to different sedimentary environments.
In this seminar, Dr. Omosebi will present results of CO2 flow-through experiment and core characterization of rock samples from the middle Duperow formation of the Kevin dome. He will also discuss wellbore integrity in carbon storage wells from a previous study. Finally, he will briefly talk about recent techniques for pressure transient analysis of non-Newtonian fluids.
About the Speaker: Dr. Omotayo Omosebi (Post-Doctoral Research Associate, Montana State University)
Dr. Omosebi has been a post-doctoral research associate in the Energy Research Institute at the Montana State University since August 2017. He previously worked as an affiliate post-doctoral research associate, graduate research assistant, and graduate teaching assistant at the Well Construction Technology Center and Mewbourne School of Petroleum and Geological Engineering, University of Oklahoma. His primary research interests are carbon storage, fluid flow in porous and fractured media, and geomechanics, with major areas of emphasis on core characterization, wellbore integrity, well test analysis, numerical simulation, and wellbore hydraulics. Dr. Omosebi holds PhD in Petroleum Engineering from the University of Oklahoma-Norman, MS in Petroleum Engineering from the African University of Science & Technology-Abuja, Nigeria, and BS in Mechanical Engineering from the Federal University of Technology-Akure, Nigeria. He is a professional member of the Society of Petroleum Engineers and a Project Management Professional of the Project Management Institute.
