CCS Site Evaluation: It’s Still Exploration

Adam Seitchik – Sr. Technical Advisor, Battelle Carbon Services

Abstract:

Although subsurface characterization for Carbon Capture and Storage (CCS) shares several petroleum systems similarities with hydrocarbon exploration, there are notable fundamental differences in evaluation criteria. Unlike petroleum systems analysis, CCS site assessment does not require consideration of source rock presence and maturation timing, and migration pathways. This distinction can lead to the misconception that identifying geologic storage sites is straightforward and low risk. In reality, it is still exploration and “dry holes” can happen. Thus subsurface evaluations for CCS involve equivalent technical rigor to reduce geologic uncertainty as much as possible. In addition, one can leverage workflows adapted from the oil and gas sector to identify and quantify risk and mitigation options. We define five primary subsurface risk domains critical to CCS site suitability: (1) reservoir presence, (2) reservoir capacity, (3) reservoir injectivity, (4) seal integrity for confinement, and (5) long-term containment. These parameters form the basis for constructing a site-specific risk profile and informing decision-making processes for project advancement. The methodology presented provides a structured approach for evaluating geologic storage potential and communicating associated subsurface risk to stakeholders for robust project decision making.

Bio:

Adam Seitchik is a Sr. Technical Advisor for Battelle Carbon Services providing technical oversight and support to technical teams, business development and management leaders. In his previous role as Subsurface Manager, he built and led a diverse team of geoscientists, reservoir engineers, and specialists. Prior to joining Battelle, he worked in the Oil and Gas industry for 24 years in both senior leadership and technical roles. During this time, he gained technical experience in various offshore basins around the world, developing a thorough understanding of the requirements necessary to mature and deliver technical projects. From this experience, Adam has implemented best practices to the carbon sequestration workflow ensuring technical standards are met. Adam graduated from the University of Alabama with Master of Science in Geology and from Denison University with a Bachelor of Arts in Geology.
