Risk-based well decommissioning
Systematically and comparatively evaluating risks for innovative well barrier design
Astrimar has established track record supporting operator well decommissioning design decisions and ALARP (as low as reasonably practicable) risk demonstration. Many wells to be decommissioned will have challenges requiring innovative designs that deviate from those specified in industry (e.g. OGUK or NORSOK) guidelines or require application of new plugging technologies. For these wells, a quantified or semi-quantified risk assessment is fundamental to demonstrating acceptable risk management and ALARP. Astrimar’s STEM-flow software supports prediction of barrier system failure over time.
