These were a reservoir engineering study and a facilities engineering study. Results are being used to assess the commerciality of Darwin in the current low oil price, but relatively low cost market.
To date the company has evaluated full-field (Darwin East and Darwin West combined) and phased developments, either of which would involve subsea well completions tied back to a leased FPSO.
The field is in around 2,000 m (6,562 ft) of water, but 14 km (8.7 mi) to the south water depths decrease to 1,100 m (3,609 ft), opening the way to alternate engineering solutions.
B&S favors a phased development, initially targeting 270 MMbbl of condensate, with four production wells and three gas re-injectors, and an initial production rate of 56,000 b/d.
Estimates by engineering contractors suggest capex of $1.36 billion, based on which B&S foresees a breakeven oil price for development of $40/bbl.
This is due to a combination of attractive fiscal terms set by the Falkland Islands government, a high quality reservoir which does not require a large number of development wells, and a relatively straightforward development plan using proven technology.
