Pohokura Field: A Pillar of New Zealand's Energy Production
Located just off the coast of the North Taranaki region, the Pohokura field stands as a critical asset in New Zealand's energy landscape. This offshore oil and gas field plays a vital role in supplying the nation's energy needs, combining strategic location with significant recoverable reserves.
Key Facts
- Location: 4 km offshore of north Taranaki, New Zealand.
- Water Depth: Approximately 30 meters.
- Discovery: Found in 2000 by Fletcher Challenge.
- Ownership: OMV (74%) and Todd Energy (26%).
- Peak Impact: Produced 42% of New Zealand's total gas in 2009.
Field Discovery and Reserves
The Pohokura field was first discovered in 2000 by Fletcher Challenge. Since its discovery, it has been recognized for its substantial 1P ultimate recoverable reserves—a technical term referring to reserves that have a high probability (typically 90%) of being recovered.
The field holds an estimated 1,227 billion cubic feet (34.7 billion cubic metres) or 1,435 PJ of gas. Additionally, it contains 61 million barrels (9.7 million cubic metres) of oil and condensate, which is a low-density liquid hydrocarbon that exists in equilibrium with natural gas.
Infrastructure and Operations
The operational setup of the Pohokura field is designed for efficiency and remote management. The field utilizes a network of 6 offshore wells and 3 onshore wells to extract resources.
The production station is situated onshore, conveniently located adjacent to the Motunui methanol plant. To optimize safety and cost, the production station is unmanned; all operations are managed remotely from a centralized control room located in New Plymouth.
Commercial production officially commenced in September 2006, marking the beginning of the field's contribution to the national grid.
Production Impact and Ownership
Pohokura has historically been a powerhouse for the region. In 2009, it reached a significant milestone by becoming the largest gas-producing field in New Zealand, accounting for 42% of the country's total gas production.
The field is currently operated by OMV, which holds a 74% ownership stake, while Todd Energy holds the remaining 26%.
