Offshore drilling and production systems and methods |
| 摘要 |
A method of drilling and producing from an offshore structure, comprising drilling a first well from the offshore structure with a drilling riser; completing the first well with a first subsurface tree; connecting the first subsurface tree to a manifold; drilling a second well from the offshore structure with a drilling riser; completing the second well with a second subsurface tree; connecting the second subsurface tree to the manifold; and connecting a production riser to the manifold and the offshore structure. |

1. A method of drilling and producing from an offshore structure, comprising:
drilling a first well from the offshore structure with a drilling riser; completing the first well with a first subsurface tree; connecting the first subsurface tree to a manifold; drilling a second well from the offshore structure with the drilling riser; completing the second well with a second subsurface tree; connecting the second subsurface tree to the manifold; connecting the manifold to a subsea boosting system comprising a caisson, an electrical submersible pump, an annular degasser, and a production riser, wherein the caisson comprises at least one length of straight tubular and at least one length of tapered tubular; and connecting the production riser to the offshore structure. |
