Gents,
Please share your knowledge on selection of subsea completion instead of platform/dry tree, etc.

Of course if we choose subsea completion, we will not need any jacket. But the cost to have some subsea completion are very high if you compare with others, especially if in life of field we have some problem with the well. To rent the vessel, they daily rate is amazing.

Actually, its usually the case that many jackets can be saved when you consider that multiple tiebacks can made to only one platform for wells up to a radius of what, 50 miles or so.

In GOM there are probably more than 1000 platforms or minimal structures built in 50 ft or less water depth, but some drilling is being done now in 4000-5000 ft depths. Out in 3500 ft depths, fixed platforms generally are far too expensive to build unless the field is a GIANT, and totally impossible in 4000-5000 ft for any size field, so subsea becomes the ONLY option, with pipeline tie-backs to depths in which tensioned structures, or maybe a fixed platform can be built.

However, the big problem of subsea is the difficulty of any kind of well intervention (I thnk there are only a handful of subsea wireline lubricators available worldwide), which is why all the work into TLPs, mini TLPs, spars, truss spares, deep draught floaters was done to get dry trees into the deep water.
