BW Energy has decided to proceed with the Maromba development project offshore Brazil and signed an agreement to purchase the FPSO Polvo from BW Offshore. The FPSO will be upgraded and redeployed on the field. The development plan is based on an initial drilling campaign of three wells with planned first oil in 2025 and a second campaign with a further three wells in 2027. The investment decision is subject to certain conditions precedent, including completion of the project financing.
- Phased subsea development with six production wells and tied back to a redeployed FPSO
- First oil from Phase 1 planned in 2025
- Expected peak oil production of 30 – 40 000 bpd
- Agreement to purchase FPSO Polvo for a total consideration of US$50 million
- Plan for efficient FPSO refurbishment and life extension established
Unlocking material production
“We have worked to optimise the Maromba development plan since the acquisition in 2019 and during the Covid-19 pandemic. This includes technical evaluations, full-spectrum analysis of geological, seismic and well data, as well as extensive reservoir modelling and simulations. Based on our findings, we have decided to proceed with a development with six horizontal production wells connected to a FPSO to unlock significant oil production and long-term value generation for our stakeholders,” said Carl K. Arnet, the CEO of BW Energy.
A development in stages enables improved reservoir monitoring and optimisation of the second drilling campaign. Total oil production at peak is expected between 30 – 40 000 barrels per day. The technical evaluation revealed that water injection is not required for the first three wells and is a contingency for the second drilling campaign. Extensive work has also confirmed that Dual Electric Submersible Pumps offer the best artificial lift solution with extended life and reduced workover frequency. The subsea layout has also been enhanced to reduce costs and facilitate future expansions.
FPSO Polvo recently ended its charter on the Polvo field in Brazil, which is located close to the Maromba field and has similar oil and reservoir characteristics. An assessment of refurbishment costs has been completed and discussions with relevant shipyards are well underway. The FPSO will be designed for up to 10 production wells with 1.2 million barrels of storage capacity. The total liquid capacity will be 85 000 barrels per day with oil production capacity of 65 000 barrels per day and water treatment capacity of 75 000 barrels per day.
BW Energy has signed an agreement to purchase the FPSO from BW Offshore effective no later than 24 July 2023, for a total consideration of US$50 million. The valuation of the FPSO has been confirmed by an independent third party. The agreement to purchase the FPSO, instead of entering a traditional lease and operate contract, is a consequence of related- and associated-party tax legislation in Brazil.
Final Investment Decision (FID)
“The FPSO Polvo is a near perfect fit for Maromba. We know the vessel well and have extensive in-house competencies and capabilities in planning and executing such a repair and life extension project. Re-using existing energy infrastructure enables reduced investments, shorter time to first oil and significantly reduced CO2 emissions in the development phase as compared to installing new production assets,” said Carl K. Arnet.
“We are also mindful of the inflationary pressures affecting our industry as we progress contract discussions with the shipyards and for other long-lead items. We are also evaluating financing alternatives for the field development plan and see strong interest from various sources,” Arnet continued.
The FID is subject to completion of the financing for the project. The Brazilian regulator, ANP, has approved the development plan and the company expects to receive full IBAMA environmental approval in due course.
Maromba is located off the Brazilian coast in the Campos Basin in approximately 160 metres of water depth. Nine wells were drilled in the license between 1980 and 2006, and oil was found in eight of these across various reservoirs. Gross 2C reserves in place are estimated at 467 million barrels with approximately 100 million barrels estimated as recoverable volumes. BW Energy acquired 100% ownership in Maromba in 2019 for a total of US$115 million, of which US$85 million remains to be paid to the sellers at predefined milestones.
The company will provide further information on the Maromba development plan in connection with the first quarter 2022 earnings release on 27 May.
