Namibia Oil: Where Does the “6.2 Billion Barrel” Figure Actually Come From?

The Origin of the 6.2 Billion Barrel Claim

The “6.2 billion barrels” figure does not appear in any single official press release from TotalEnergies, GALP, Shell, or Namibia's Petroleum Commissioner. It emerged from early 2022–2023 media reporting that aggregated preliminary resource announcements across Namibia's first wave of major deepwater discoveries without clearly distinguishing between in-place and recoverable volumes.

In February 2022, TotalEnergies announced the Venus discovery in PEL 56, describing it as “a giant oil discovery” with “more than 2 billion barrels of recoverable resources.” That same year, Shell confirmed two additional discoveries in its Orange Basin portfolio — Graff-1 (Block 2913A) and La Rona-1 (Block 2912A) — with preliminary estimates suggesting a combined resource base of several hundred million barrels. Media outlets combined these numbers, added optimistic unrisked prospective resource estimates for adjacent acreage, and arrived at aggregate figures ranging from 6 to 8 billion barrels that were widely repeated throughout 2022.

NAMCOR, Namibia's National Petroleum Corporation, issued its own preliminary aggregate of approximately 11 billion barrels across named discoveries in 2023 — a figure that used in-place resource volumes (the total oil present in the reservoir) rather than recoverable volumes. This distinction is critical and is where much of the confusion originates.

The “6.2 billion barrel” figure most likely represents a subset of those early aggregate estimates, possibly combining Venus's initial recoverable figure with in-place estimates from Shell's Orange Basin portfolio, or reflecting a specific media compilation from mid-2022 before full appraisal data was available. No operator has published an official combined resource estimate of exactly 6.2 billion barrels for Namibia.

Verified Recoverable Estimates by Field (March 2026)

The following figures are sourced from official operator announcements, investor presentations, and company filings. Where operators have provided ranges, both ends of the range are shown. These are recoverable resource estimates, not in-place volumes.

Namibia Oil Resource Summary: Verified Numbers vs. Media Claims

Why the Gap Between In-Place and Recoverable Matters So Much

Mopane is the best illustration of how dramatically these two numbers can diverge. GALP's in-place figure of 10+ billion barrels generated headlines comparing the discovery to Guyana and Brazil. The recoverable estimate — roughly 800 million to 1.1 billion barrels — tells a completely different story in terms of commercial scale and FPSO sizing.

A typical deepwater oil field in sub-Saharan Africa achieves a recovery factor of between 20% and 35% of STOIIP, depending on reservoir quality, fluid type, and development technique. Applying a 25% recovery factor to Mopane's 10 billion barrels STOIIP yields 2.5 billion barrels recoverable. The lower published estimate of 800 million barrels suggests either a more conservative recovery factor (around 8%) or that the commercially viable reservoir sections represent a smaller fraction of the total in-place volume — which is common in complex carbonate or mixed-lithology reservoirs like those found in the Orange Basin.

The practical investor implication: always identify which metric you are reading. In-place volumes drive media excitement. Recoverable volumes drive FID decisions, FPSO capacity, and ultimately the cash flows that determine equity value.

How Namibia's Numbers Compare to Other Major Oil Discoveries

Context helps explain why Namibia attracts the interest it does, even when recoverable resources are substantially smaller than in-place estimates suggest.

What Should Investors Actually Focus On?

The 6.2 billion barrel figure — whatever its origin — is ultimately a distraction from the questions that drive investment returns in a frontier oil province. The metrics that matter are:

The Bottom Line on Namibia's Oil Resources

The “6.2 billion barrel” figure that circulates widely for Namibia's oil is not an official operator number. It is a media aggregation of early, preliminary estimates that blended in-place and recoverable volumes across different fields and timeframes. Tracking it down to a single authoritative source is not possible because no such source exists.

What is verified: Namibia's named offshore discoveries hold approximately 3.4 to 4.2 billion barrels of recoverable oil across Venus, Mopane, and Shell's Orange Basin portfolio. That makes Namibia's confirmed resource base roughly comparable to Ecuador's total proven reserves or Colombia's — substantial by any measure, and more than sufficient to justify the multi-decade development programmes currently in planning.

The more important question is not whether the number is 3.4 billion or 6.2 billion barrels — it is whether FIDs get taken on schedule, whether deepwater infrastructure costs come in on budget, and whether Namibia's fiscal framework remains stable enough to attract the long-term capital these projects require.

Those are the variables that will determine whether Namibia becomes the next Guyana or the next frontier market that failed to convert its geology into sustained production. For a full assessment of the risks involved, see our Namibia oil investment risks guide.
