A review of risk and uncertainty assessment for geologic carbon storage

Effects of Injection Temperature and Pressure on CO2 Storage Capacity and Safety in a Sloping Formation

“…Risk and uncertainty assessment are crucial for ensuring the safety and reliability of CGS by evaluating CO 2 migration in the subsurface . Injection capacity and storage safety of CO 2 have always been issues of concern for CGS projects, which are affected by several factors including injection well configuration, injection conditions, brine salinity, porosity and permeability heterogeneity, and faults and reservoir temperature. − CO 2 storage capacity can be evaluated by assessing the leakage risk after CO 2 injection. , …”

Integrity Experiments for Geological Carbon Storage (GCS) in Depleted Hydrocarbon Reservoirs: Wellbore Components under Cyclic CO2 Injection Conditions

“…Its integrity guarantees a safe and long-term operation. Any failure of wellbore integrity will have serious consequences on the operations and, most likely, on the environment as well [12,13].…”

“…Many studies on typical wellbore cement (like class G and H cement) reported cement degradation due to interaction with CO 2 [14][15][16][17][18][19][20]. Other studies focused on the reactivity of CO 2 with casing or rocks [12,[21][22][23]. Moreover, the studies have been extended to study composites or wellbore sections (two components, e.g., casing-cement or cement-rock) under various CO 2 operation conditions [24][25][26][27][28].…”
