Subsection 21(8)(b) | The GHG substance that is suitable to store | 97 mol% -100 mol% CO2 |
Subsection 21(8)(c) | The injection point or points | Primary injection site: 3-5 injection wells approximately 3 km from each other and 10 km south of the Calliance field.
Contingent injection site: 1 injection well located approximately 5 km northeast of Calliance-1. |
Subsection 21(8)(d) | The injection period | 31 years |
Subsection 21(8)(e) | If subsection 21(1)(b) is applicable, the engineering enhancements | N/A |
Subsection 21(8)(f) | The effective sealing feature, attribute or mechanism of the storage formation that enables permanent storage | Combination saline aquifer-structural trapping below the J50.0 to K50.0 deep-marine mudstone seal. |
