Scenario Modelling to Support Monitoring Plans for CO₂ Storage Sites

Quintessa contributed to a review of technologies and approaches for measurement, monitoring and verification (MMV) of possible future offshore CO2 storage sites adjacent to the UK.

The project was led by the British Geological Survey (BGS) for the Energy Technologies Institute (ETI). Quintessa simulated the movement of CO2 in different kinds of CO2 storage sites as a basis for judging which MMV technologies and approaches would be appropriate in each case. Four hypothetical sites were specified to represent the range of storage options in the northern and central UK North Sea. Hypothetical, unexpected leakage scenarios involving flow through wells, faults and enhanced permeability zones were modelled using Quintessa's QPAC software.
