Pressure control and conformance management for safe and Efficient CO2 storage - Accelerating CCS technologies (Pre-ACT)
The objective of the Pre-ACT project (2017-2020) was to equip operators and regulators with pressure-driven decision support protocols (Pre-ACT Protocols) that enable them to establish a safe and efficient monitoring system and to assess quantitatively site conformance. These protocols can be adjusted to each project phase yet provide a common basis for decision making during operation and at site handover.
