A new front
Transformational international expansion
In April 2026 Block became a multinational independent energy company, taking a 76.5% indirect economic interest in the contiguous Ndjila and Mpari PSCs in the North Gabon basin offshore West Africa.
Gabon is a mature hydrocarbon province with established operators, export routes and a long production history. The region’s subsurface and surface potential have been validated by recent investments by majors including Exxon, BP and Trafigura.
Ndjila and Mpari, covering a combined area of 5,331 km2 containing four historical oil discoveries drilled by operators including Texaco, Shell and Tullow, offer 75 MMbbl (pMean) discovered oil with up to 870 MMbbl (pMean) STOIIP upside. Ndjila and Mpari’s dataset includes near‑full coverage, and a modern 3D seismic survey acquired in 2017. Multiple mapped leads and prospects have been identified in the pre‑ and post‑salt sections.
The US$6m investment is supported by tested oil discoveries and low-cost commitments. Anchor field Iguega’s discovery well tested at rates of 3,300 bopd, and a development concept envisaged 23 MMbbl (pMean) recoverable was previously completed by Shell. Three other structures offer an additional 52 MMbbl (pMean) discovered oil.

Programme
A low-risk, desktop-based programme designed to rapidly advance Iguega and the wider portfolio towards farm-out and development
- Packaging Iguega for near-term farm out and development (production potential c. 8,000 bopd)
- Re-mapping licences to define full prospect and lead portfolio, as well as evaluation of remaining four oil discoveries for farm-out
- Operations supported by Block’s technical and operational capability and Board experience in West Africa
- Proven basin significantly reduces both capital exposure and time to develop the assets to farm-out ready status

Other projects
Project I
Project I combines established production, development potential, and innovative drilling techniques to generate cash flow, support future growth, and maximise value across the wider portfolio
Project II
Project II is focused on realising the substantial potential of the Patardzeuli-Samgori field, leveraging a large contingent resource base, proven production history, and attractive development opportunities
Project III
Project III is focused on developing a significant gas resource with multi-trillion cubic feet potential, supported by strategic partnerships and long-term value creation opportunities
Project IV
Project IV targets significant exploration upside across multiple licences, supported by a strategic farm-out partnership and a fully funded programme designed to unlock substantial resource potential
Carbon Capture and Storage
Our CCS initiative has the potential to establish a major CO₂ storage hub in Georgia, supporting industrial decarbonisation and contributing to long-term net-zero objectives
