Well Engineering for CO2 Storage Applications (EC033)

Course Summary

This course covers the design specifics of CO2 injection wells. Such wells may be existing or new wells which need to be designed with the challenges of CO2 injection in mind. The design includes the casing, cement, completion and all associated equipment. The challenges covered included potentially highly corrosive (to metals and cements) fluids, large temperature changes associated with potential phase changes and the long-term integrity requirements. In addition to casing design and cement design, equipment selection (such as packers with their associated elastomers) and tubular connections will be examined for their suitability for CO2 injection. Legacy offset wells will be examined for potential leak paths over the long-term. Examples from existing and planned schemes will be reviewed throughout.

Attendees should be capable well engineers (completions or drilling) or technical specialists such as chemists, geomechanics, or material specialists.

Learning outcomes

Participants will learn to:

  1. Evaluate well integrity with respect to CO2.
  2. Consider the challenges that CO2 gas versus dense phases present and undertake PVT calculations.
  3. Assess the corrosive impacts of CO2 including the impact of stress corrosion at low temperatures.
  4. Formulate stress calculations for the liner, production casing and tubing.
  5. Analyse the issues of cement design for CO2 wells, including both legacy and new well designs.
  6. Examine the issues involved in repurposing existing wells with reference to existing casing designs and cement evaluation.
  7. Construct risk assessments and understand monitoring technology and regulatory frameworks.
