Joint inversion of multi-component seismic data: application to Bakken petroleum exploration and development
The Reservoir Characterization Project (RCP) at Colorado School of Mines acquired the rights to a 9C, 3D seismic survey in Mountrail County, North Dakota with specific focus on how multi-component seismic data could aid in exploration and development of the Bakken Shale (Figure 1). Proximity to the giant Parshall Field made the survey particularly attractive as operators in the Bakken wanted to find if additional value could be created by acquiring multi-component seismic data in this major unconventional resource play. The Bakken Petroleum System (Figure 2) includes the Three Forks, Bakken, and Lodgepole Formations. Depositional environments of the Devonian Three Forks range from supratidal to shallow marine. Overlying the Three Forks is the organic-rich Bakken Formation which was deposited in a stratified offshore marine environment. It is Late Devonian and Early Mississippian in age. After Bakken deposition, sea level rose causing marine transgression and deposition of the Mississippian subtidal Lodgepole Formation.
