This initial session focuses on site selection and the screening processes involved, including key factors for storage selection related to storage capacity. The benefits of a holistic site characterization for subsurface fluid storage will be discussed and compared to traditional approaches for oil and gas exploration, with emphasis on the overburden section. This session will also discuss the geological and reservoir fundamentals for storage hereunder, containment mechanisms and requirements, and risk factors associated with storage, including induced seismicity and wellbore integrity.

Chairpersons: PK Pande, Energy Fuse Group; Valerie Wilson, AirMyne

Carbon capture and storage (CCS) project infrastructure and commercial aspects are paramount for moving projects to a final investment decision (FID) and implementation.  This session integrates elements of the CCS value chain, including capture, transport, wells/facilities, and subsurface with commercial/finance, regulatory, and stakeholder management aspects to effectively implement projects in 2025 and beyond.

Chairpersons: Seunghee Kim, University of Nebraska-Lincoln; Denis Klemin, SLB; Willow Liu, MEDENG

This session focuses on products-reservoir interactions during various operations, such as underground gas, CO₂, hydrogen, compressed air, and thermal energy storage. These interactions include gas-brine-rock reactions, microbial interactions, pressure cycling effects, and consequent mechanical implications. This session also explores advanced characterization methods for subsurface storage.

Chairpersons: Alberto Casero, bp; Valerie Wilson, AirMyne

Storage wells serve as a conduit for liquid and gaseous fluids for their periodical use or permanent sequestration, adding more stringent design requirements to address cyclical pressure loading, temperature transitions, zonal isolation, and corrosion. While the general approach to design, construction, and integrity is similar and derived from producers and injector wells, this session will focus on the special needs to ensure the safe and compliant operability of the storage well during its life cycle.
