Splitter wellheads allow to drill several wells from the same conductor pipe, which can bring significant benefits for conventional offshore developments by reducing the size and/or number of new wellhead platforms or by giving access to additional reserves from available platform slots.

In April 2003, Cameron 9" dual Conductor Sharing Wellheads (CSW) were successfully installed by Total E&P Indonésie on Peciko offshore gas field development as the first worldwide application in a 30" conductor pipe of a 9" x 10,000 psi dual splitter wellhead and 4-1/2" x 6,500 psi Xmas-Tree.

As a result, 120 MUSD could be saved on surface facilities costs by reducing the total number of wellhead platforms from 10 to 7 while targeting the same gas reserves. Drilling and completion costs remained in line with initial budgets, as the higher costs of long departure wells induced by the reduced number of platforms were balanced by the savings made with the slimmed down well architectures.
