ABOUT REX-CO2
Objectives
REX-CO2 will increase the technical feasibility and economic competitiveness of high-potential depleted hydrocarbon fields earmarked for CO2 storage. The specific objectives are:
- Develop a publicly available well re-use screening tool which helps stakeholders to make informed decisions on the CCS re-use potential of certain wells or fields
- Demonstrate the application of the developed tool to perform dedicated re-use assessment, including technical, ecological and economic aspects with candidate wells/fields from multiple international sites
- Perform laboratory testing on relevant re-use risk scenarios, provide recommendations for (smart) material selection in re-used wells; feed coupled thermo-hydraulic-mechanical-chemical (THMC) models and improve failure predictions
- Provide guidance for the development of re-use permit applications
- Gain an improved understanding on public acceptance and provide guidance on the socio-economic aspects of re-using oil and gas infrastructures
Outcomes
The results of REX-CO2 are expected to facilitate large-scale CCUS implementation by providing a tool to evaluate and rank the CO2 re-use potential of hydrocarbon fields. The developed technology is not limited to a particular sector of CO2 storage but will accelerate all types of CCS. Key results will include:
- Synthesised findings from developing a public re-use well screening tool for re-using existing hydrocarbon fields
- Key findings in laboratory experiments, including well cement state of stress, material self-healing potential and implications for integrity of re-used wells
- Field scale numerical simulation results for different re-use field scenarios
- Field case re-use studies for selected wells and depleted fields in all six partner countries
- Assessment of public acceptance and recommendations for future projects involving well re-use for CO2 injection/storage
- Development of technical and socioeconomic best practice recommendations for re-using existing wells for CO2 storage
