A New Economical Method of Subsea Completion for Jackup Depth Waters

Abstract This paper describes a new economical concept in subsea drilling and completion that has allowed the justification and recent installation of a diver-assist wet subsea tree in the Gulf of Mexico from a jack-up rig. This concept reduces costs on subsea completions and now makes profitable the production of innumerable small reservoirs, either looked at and counted uneconomical by previous parameters, or yet to be discovered small reservoirs in the marine environment. The simplicity of this concept greatly reduces costs and allows the operator to use the concept on every exploratory well drilled from a jack-up rig.
