Total has started production from a new development on its deep offshore operated Block 17 located 135km off the coast of Angola.
Developing extra reserves of 51 million barrels (Mb), the new Dalia Phase 1A will contribute 30,000 barrels per day (bpd) to the block’s production.
Total exploration and production president Arnaud Breuillac said: "The Dalia FPSO came on stream nearly nine years ago and with the addition of Phase 1A will still produce around 200,000bpd.
"It is the latest milestone in the success story of Block 17, Total’s most prolific licence with cumulative production reaching two billion barrels in May 2015."
According to Total, the Dalia Phase 1A development is part of its plan to to increase value through the optimal use of existing facilities.
Breuillac added: "These types of profitable satellite tie-back developments play an important role in maintaining production levels and generating additional free cash flow for the group."
As part of the Dalia Phase 1A project, seven infill wells that are tied back to the Dalia floating production storage and offloading (FPSO) unit will be drilled.
Block 17 is 40%-owned by Total and the other partners include Statoil (23.33%), Esso Exploration Angola (20%) and BP Exploration Angola (16.67%).
Sonangol is the concessionaire of Block 17.
Total operates four FPSO units on the major production zones of the block, which include Girassol, Dalia, Pazflor and CLOV.
