Well intervention
Panelists at the SPE Subsea Well Intervention Symposium discussed where AI is delivering value today, where risks remain, and how engineers can best determine its usefulness.
With millions of wells having been drilled in the US since the beginning of the oil age, the land is pocked with old, unused wellbores. For most, repurposing is a pipe dream. Plugging is the best option.
This article from the SPE Research and Development Technical Section offers new insights to how the upstream industry can benefit from the emergence of quantum computing.
