Reducing the level of carbon in the atmosphere to safe levels will require both a reduction in emissions and a significant carbon removal programme. In fact, experts indicate that even if we reduce emissions to zero, existing carbon gases need to be removed from the atmosphere to prevent further climate change. Carbon capture facilities of all types are emerging globally, and some involve storing CO2 underground in depleted oil and gas fields.
Storing CO2 underground is similar to methane storage. Well and reservoir integrity is vital to avoid leakage. TGT’s True Integrity products can be used to validate integrity prior to re-purposing existing well systems, and True Flow products can be used to ensure that 100% of the injected gas is reaching the target formations. And just like conventional producing well systems, storage wells can be monitored routinely to ensure integrity compliance.
