Statoil and its Peregrino field partner Sinochem submitted its US$3.5 billion development plan for the Peregrino Phase II project to Brazilian regulator, the National Agency of Petroleum, Natural Gas and Biofuels, at the end of January, the Norwegian explorer announced on 27 February.
The project was officially sanctioned in December. The development plan calls for a new well head platform and drilling rig (Platform C) to tie back to the Peregino FPSO. The facilities will have standalone power generation and will export power to well head platform A. Statoil says this will add 250 MMbbl in recoverable resources at the field out to 2040.
Phase II will also include a total of 21 wells, 15 oil producers and six water injectors. The wells will be drilled in a new area called Peregrino Southwest, which Statoil says is not currently reachable by the existent platforms A and B.
All the production and injection wells in the Phase II development are planned to be drilled from Platform C, which will reside in 120 m water depth.
“Peregrino Phase II will strengthen our position in the country and reinforce our long-term commitment for the development of Brazil”, says Pål Eitrheim, senior vice president and Brazil country manager.
Statoil expects Phase II startup by the end of the decade.
Peregrino field is located 85km (53mi) off the coast of Rio de Janeiro in the 115,000km (71,457mi) Southern Campos Basin area. Statoil says Peregrino has produced more than 90 MMbbl since first oil in April 2011.
At OTC Brasil in 2013, Statoil’s former senior vice president and president of Statoil Brazil, Thore E. Kristiansen, said the Norwegian company believed it could double recovery at the field when it acquired it from Maersk in 2012. Peregrino is a heavy oil field, measured at 14 API. Kristiansen said Statoil opted to drill 30 long horizontal wells with open hole gravel pack and screens at Peregrino.
Additionally, Kristiansen said Statoil used artificial lift with electrical submersible pumps (ESPs), topside boosting, and water cut (>50%) downstream wellheads. The Peregrino FPSO supplies continuous water circulation and generates enough heat to separate the viscous oil and water, he told the OTC crowd.
