Zinia 2

Project Overview

The Zinia Phase 2 oil project is a deepwater offshore development located in Block 17, approximately 150 kilometers off the coast of Angola.

Location and Geology

• The project is situated in water depths ranging between 600 and 1,200 meters.
• Block 17, often referred to as the "Golden Block," is known for its high productivity and has produced over 2.6 billion barrels of oil to date.

Ownership and Partners

• The block is jointly owned by Total Exploration and Production (Angola) as the operator with a 40% stake, Equinor (23.33%), ExxonMobil (20%), BP (16.67%), and Sonangol P&P (5%).

Project Details

• The Zinia Phase 2 project involves the development of a satellite field tied back to the existing Pazflor Floating Production, Storage, and Offloading (FPSO) facility.
• The project area covers approximately 600 square kilometers and includes the drilling of nine development wells, with five oil producers and four water injectors.

Infrastructure

• The wells are connected to the Pazflor FPSO through a new subsea pipeline network, which includes:
  • A 10.3 km-long electric heat tracing (EHT) pipe-in-pipe flow line with an 11-inch inner diameter.
  • A 13.6 km-long water injection line with an 8.5-inch inner diameter.
  • A 10.5 km-long non-insulated gas lift line with a seven-inch inner diameter.
• The subsea production lines connect the wells to the existing P40L riser for the Pazflor FPSO, involving 49 tie-in works at the FPSO, including 31 cold and 18 hot works, along with modifications to the existing water injection and gas lift modules.

Production

• The project is expected to produce approximately 40,000 barrels of oil per day (bopd) and is estimated to reach this production level by mid-2022.
• The recoverable resources for Zinia Phase 2 are estimated at 65 million barrels of oil.

Contractors and Contracts

• Total awarded the engineering, procurement, commissioning, and installation (EPCI) contract for subsea flowlines and umbilicals to Subsea 7, valued between $150 million to $300 million.
• TechnipFMC was awarded the contract for the engineering, procurement, and construction (EPC) of subsea equipment, including nine subsea tree units, subsea control systems, wellheads, and connection systems.

Investment and Timeline

• The final investment decision (FID) for the project was made in May 2018, with an estimated investment of $1.2 billion.
• The project was completed within the scheduled timeline, despite challenges from the COVID-19 pandemic, and the final capital expenditure was more than 10% below budget, resulting in a saving of $150 million.
• Production from the Zinia Phase 2 project started in May 2021.

Historical Context and Significance

• The Zinia Phase 2 project is part of a broader development strategy in Block 17, which includes other major field complexes such as Girassol, Dalia, Pazflor, and CLOV (Cravo, Lirio, Orquidea, and Violeta).
• This project reflects the industry's move towards more efficient and cost-effective short-cycle developments, which are crucial for sustaining production levels in Angola.

Environmental and Safety Considerations

• The project involved more than 3 million man-hours of work, with 2 million of those hours performed in Angola, without any incidents.

In summary, the Zinia Phase 2 project is a significant deepwater development that leverages existing infrastructure to enhance oil production in Block 17, Angola, while demonstrating efficient project execution and cost management.
