Installing a TAML L-4 multilateral system in deepwater Schiehallion field ///

The Schiehallion field lies in 1,150—1,475-ft water depths about 103 nautical miles west of the Shetland Islands. The reservoir was discovered in 1993 and brought on stream in 1998. It is the largest BP-operated field in the region and is one of the UK’s largest producing fields. There are presently 19 production wells and 19 water-injection wells. Initially, the field’s North West Area Development (NWAD) was to have four wells, two producers with two injectors. However, design and economic reviews indicated that development with a multilateral well and matching injectors was more viable. The selected system consisted of a hollow whipstock through which perforations would be made after installing the completion. The original well design had the lateral legs produce and commingle through a single completion string. During detailed planning, this design was challenged and adapted for remote Down Hole Flow Control (DHFC) of each lateral’s production.
