PARALLEL DRILLING AND COMPLETION FOR A DRY TREE FLOATING PRODUCTION FACILITY

摘要

Field development drilling and completion/production work are performed from a floating facility having a deck with a moon pool and a well bay, a first drilling rig fixed to the deck over the moon pool, and a second drilling rig movably mounted on the deck over the well bay. In use, the facility is positioned in a first position for field development drilling by the first drilling rig through the moon pool at a first well location. The facility is moved to a second position for field development drilling by the first drilling rig through the moon pool at a second well location. During the field development drilling at the second well location, the facility is moved so that the first well location is accessible through the well bay. Well completion/production work is performed at the first well location through the well bay with the second drilling rig.
