Statoil and Sinochem add new platform in Peregrino II
The state-owned companies Statoil from Norway and Sinochem from China, partnering in the offshore Peregrino field, submitted the plan of development (POD) for its southwest expansion in the Campos Basin to Brazil National agency of Petroleum, Natural Gas and Biofuel (ANP).
Despite its 14-degree API heavy crude oil and its related challenges, Peregrino attracted foreign companies for exploration and production.
On the positive side, Peregrino is ranked among the largest post-salt oil and gas fields in the Campos Basin offshore Brazil.
Since heavy crude oil requires a larger quantity of wells for injection as well as for production, Peregrino reasonable water depth enabled Statoil and Sinochem to maximize subsea operations at reasonable costs.
– Statoil 60% is the operator
– Sinochem 40%
Statoil and Sinochem started first operations in Peregrino in April 2011 with a floating, storage, production and offloading (FPSO) vessel fed by the drilling and wellhead platforms A and B.
Statoil completed Peregrino Phase-2 FEED work
Since the early days of production, Statoil and Sinochem decided to deploy the enhanced oil recovery (EOR) techniques to boost the heavy crude oil production in combining horizontal wells, flow assurance and water injection.
In order to optimize the learning curve on this complex heavy crude oil field, Statoil and Sinochem decided to start the pre front end engineering and design (pre-FEED) for Peregrino Phase-2 project soon after Phase-1 first commercial operations.
With $3.5 billion capital expenditure, Peregrino Phase-2 is expected to add 250 million barrels of recoverable reserves of crude oil from the southwest area of the field.
From the completed front end engineering and design (FEED) work, the Peregrino Phase-2 will see the addition of a Southwest wellhead platform (WHP-C).
This third drilling and wellhead platform will add 15 production wells and 6 water injection wells and will be tied-back to the existing FPSO.
This Peregrino Platform-C will also support its own standalone power generation and will be able to power supply the Platform-A for further extension of EOR equipment.
