Subsea well completion design and implementation in Total’s (formally TotalFinaElf’s) Aconcagua field and Marathon Oil Co.’s Camden Hills field posed unprecedented challenges, Water depths in the area of planned development (up to 7,209 ft) were greater than for any well previously completed in the world. Limited gas reserves in this high-cost, deepwater environment precluded future economic intervention, so the completion design had to balance the potential complexity of multiple-zone production with high life-of well reliability.
