Advances in subsea interventions

There are about 4,000 subsea wells producing oil and gas around the world, and with many now over a decade old, intervention is crucial to maintain production volumes. However, subsea well intervention is a time-consuming, costly activity, with heavy rig costs running up to $1 million per day. Several companies have been developing more cost-effective workovers, downhole completion equipment and P&As of subsea wells in various water depths. Here are the latest innovations from Expro, FMC Technologies, Superior Energy Services, Blue Ocean, Lewis and others, including some new underwater technologies to make subsea operations easier.
