INJECTWELL - Experimental and Numerical Assessments of CO2 Injectivity and Flow Assurance during Storage in Depleted Hydrocarbon Reservoirs

What we do

The project delivers new experimental understanding of wellbore integrity and near-wellbore reservoir effects and phenomena dedicated to CO2 injection into depleted hydrocarbon reservoirs (DHR), including a benchmarking of commercial simulators with improvement-suggestions necessary to mature risk assessments and techno-economic analyses for sustainable CO2 injection into DHR and geologic carbon sequestration (CGS) projects in general.

Why is this important?

Handling the coupled and combined CO2 flow dynamics/aspects (well-reservoir), is the main driver of this project. Better understanding of these aspects is necessary to secure CO2 injections at planned injection rates and to accelerate the implementation of more CGS projects.

Goals

- Recommendations on optimal operational windows for CO2 injection in terms of well integrity and injectivity (well-to-reservoir) based on calibrated modelling results and experimental data.


- Guidelines and improvement-suggestions on the selection of simulation tools in terms of reliability, flexibility and practical applicability.
