Dalia FPSO – Total

Dalia was discovered in 1997, 135km offshore in water depths of between 1,200m and 1,500m. The launch of Dalia, which came onstream in late 2006, was a significant step in the development of block 17, where 15 earlier discoveries have been made. It followed the development of nearby Girassol, brought onstream in late 2001, and Jasmim, a Girassol satellite.

By repeating Girassol, but on a much larger scale and under even more extreme conditions, Dalia boosts production on this golden block to around 500,000bpd. In total, the development of the Dalia project represents an estimated investment of over $4bn.

The production in December 2006 was over 200,000bpd. It is expected to increase to 240,000bpd. The proved and probable reserves are around one billion barrels.

The concessionaire of block 17 is Sonangol. TotalFinaElf has a 40% interest in block 17 along with Esso Exploration Angola (block 17) Ltd (20%), BP Exploration (Angola) Ltd (16.67%), Statoil Angola block 17 AS (13.33%) and Norsk Hydro (10%).

Dalia FPSO

The FPSO vessel for Dalia constitutes a second pole of production on Block 17. Capable of processing 240,000bpd, the Dalia FPSO has a storage capacity of two million barrels of oil.

The FPSO vessel, built in South Korea, has a hull dimension of 300m in length, 60m in breadth and stands 32m high. On top of this is 29,400t of topsides, including I-tubes.

It has a water injection capacity of 405,000bpd, water treatment capacity of 265,000bpd and gas compression capacity of 8mscf per day. The total installed power capacity is 66MW.

The living quarters can accommodate up to 120 people and up to 190 during shut-downs. The structure has a design working life of 20 years.
