Description

Different maturity levels of CO2 and energy storage studies will be presented and discussed, focusing on capacities, containment (trap, reservoir properties, top seal and their assessments). The workshop will discuss large scale screening studies and detailed reservoir simulations with a focus on e.g., individual well injectivity rates and the optimalisation of number and type of wells needed to reach anticipated capacities. Furthermore, the workshop will gather contributions focusing on assessment of historical hydrocarbon exploration areas bringing new insights on legacy well characterization, monitoring, and capacity estimates.

Sub-Topics that will be covered in the workshop:

Subsurface assessment of storage sites, focusing on their:

  • container size & properties (trap, reservoir properties, and their assessments),
  • assessment of the top seal & leakage risks; and also the
  • mapping & size and impacts of the connected aquifer for the regional/local pressure build-up.
  • estimation of the individual well injectivity rates and the
  • optimalisation of number and type of wells needed to the desired total project injection capacity

Evaluation and risk-assessment of shut down fields bringing new insights on:

  • legacy well characterization
  • monitoring of potential leakage
  • capacity estimates

Participant Profile

Geoscientists (geologists, geophysicists, geo-modellers, petrophysicists) & reservoir engineers, drilling engineers, economists working with the assessment & development of CCS sites and projects.
