PARALLEL DRILLING AND COMPLETION FOR A DRY TREE FLOATING PRODUCTION FACILITY
First Claim
1. A floating facility for performing field development drilling simultaneously with well completion or hydrocarbon production work, the facility comprising:
- a hull structure including a deck and first and second openings, each opening providing access through the deck to a seabed;
a drilling rig fixed to the deck above the first opening, the drilling rig being operable for field development drilling through the first opening; and
a completion rig movably positioned on the deck above the second opening, the completion rig being horizontally movable with respect to the deck, and being operable to perform well completion and production work through the second opening;
wherein the drilling and completion rigs are operable simultaneously.

Abstract
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.

12. A system for performing field development drilling and completion/production work, comprising:
-
a floating facility having a deck with a moon pool and a well bay; a drilling rig fixed to the deck over the moon pool and operable to perform field development drilling into a seabed through the moon pool; and a completion rig movably mounted on the deck over the well bay and operable to perform well completion and production work in the seabed through the well bay while the drilling rig is performing field development drilling. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A method for performing field development drilling simultaneously with well completion or production work from a floating facility having a deck with a drilling moon pool and a well bay, the method comprising:
-
(a) positioning the facility in a first field development position for performing field development drilling at a first well location; (b) performing field development drilling through the drilling moon pool at the first well location with a drilling rig fixed to the deck above the drilling moon pool; (c) moving the facility to a second field development position for performing field development drilling at a second well location; (d) performing field development drilling through the drilling moon pool at the second well location with the drilling rig; and (e) during the performance of the field development drilling at the second well location, performing well completion or production work through the well bay at the first well location with a completion rig movably positioned on the deck above the well bay. - View Dependent Claims (24, 25, 26, 27, 28)
