Course Content

The development and application of a fit-for-purpose CO2 injection model is presented in the context of a front-end engineering design for a new Carbon Capture Storage (CCS) project targeting a depleted gas reservoir in the North Sea. The growing trend towards long-term industrial scale CCS presents challenges for wellbore tubular design. Along with related CCS system components such as the pipeline or the reservoir, particular engineering design and integrity assurance requirements must be addressed for the wellbore tubulars. Downhole operating conditions include severe cooling from Joule-Thomson effects across chokes, due to wellbore friction and at the sand face. Coupled with drilling and cementing conditions from the well construction phase, the resultant thermal stresses on tubulars, connections and completion components need to be predicted as they can be significant.  An appropriate Equation of State, accounting for impurities and multiphase flow correlations are required to predict rapid changes in fluid behaviour. With a depleted gas reservoir as the storage target, early life versus late life wellbore conditions can be significantly different. The tubular design workflow was finalized using the CO2 injection model deployed via a cloud-based software platform developed in concert with the FEED process in an agile manner. Validation of the model was provided by comparison with legacy software.

This course will provide an understanding of the impact of CO2 impurities on casing and tubing load cases. The course provides the background and results of the Fit-for-Purpose Casing and Tubing Analysis Program that was developed in collaboration with Harbour Energy for the UK Viking CCS Project.
