Carbon Capture and Storage (CCS) is a key means of mitigating climate change and is the only option currently available to decarbonize industries such as cement, steel, petrochemicals and LNG.  As opportunities in oil and gas decline, they are growing in CCS. Human activities now generate about 35Gt of CO2 (1 gigatonne=1 billion tonnes) per year. At ~$50/ton for sequestration, the potential opportunity is enormous, both in new business revenue and in repurposing old assets and delaying decommissioning costs. Mitigation of the worst effects of climate change will require storing billions of tons per year, with an industry to match. In the US alone, the National Petroleum Council estimates that CCS could employ ~230,000 people, similar to the current oil industry.  This course empowers attendees to develop and apply their skills to the growing industry of Carbon Capture Utilization and Storage. Attendees will be guided through the subsurface characterization and risk assessment of a storage site. Focus will be on the geologic needs for site definition, screening and development.

This course is aimed at subsurface oil and gas professionals and first-level leaders who would like to develop their skills for the emerging industry of carbon capture and geologic storage (CCUS). It is recommended specifically for:
  • Geologists, geophysicists, reservoir engineers and other technical subsurface O&G professionals interested in CCUS
  • First-level leaders and others tasked with developing and/or assuring geologic storage for CCUS projects
  • Recent graduates in petroleum geoscience and reservoir engineering who want to develop skills in CCUS


Susan Hovorka

Dr. Susan Hovorka is a sedimentologist who works on fluid flow in diverse applications, inlcuding water resource protection, oil production, and waste storage. She has led a team working geologic storage of CO2 since 1998, with a focus on field studies, monitoring, and capacity estimation. Projects include saline injection at the Frio Test site and Cranfield Field and EOR studies at SACROC oil field, Cranfield, Hastings and West Ranch industrial CO2 utilization projects and GoMCARB offshore charaterization study. She specializes in monitoring to document retention. The Gulf Coast Carbon Center is leading efforts to develop offshore storage capacity in the the US and globaly.

She has a long-term commitment to public and educational outreach.
