Uganda Names Its Crude ‘Pearl Sweet’ as First Oil Comes Into View
UGANDA · OIL
Key Facts
—The name: President Yoweri Museveni unveiled the blend name at a ceremony at the Kingfisher Development Area in Kikuube district, under the slogan ‘Born of the Pearl’. ‘Sweet’ refers to low sulphur content and ‘Pearl’ to Uganda’s description as the Pearl of Africa.
—What is in the blend: Pearl Sweet commingles crude from the TotalEnergies-operated Tilenga development and the CNOOC-operated Kingfisher development.
—The quality: It is a medium-light crude of roughly 28 to 31 degrees API gravity, with low sulphur. That is the grade refiners generally pay up for.
—Peak volumes: Tilenga is designed for about 190,000 barrels a day at peak and Kingfisher for about 40,000, giving roughly 230,000 barrels a day combined.
—How it leaves: Streams are commingled at the Kabaale hub in Hoima district before entering the East African Crude Oil Pipeline for export through Tanzania.
—The state’s share: Uganda’s national oil company UNOC holds a 15% participating interest in both Tilenga and Kingfisher, and will help market the crude.
Uganda Pearl Sweet crude is the name the country has given the blend it expects to start selling this year, unveiled by President Yoweri Museveni at a ceremony in Kikuube district. It is a medium-light, low-sulphur grade combining output from two developments that took almost twenty years to reach this point.

What Uganda Pearl Sweet crude actually is
The blend commingles production from Tilenga, operated by TotalEnergies, and Kingfisher, operated by CNOOC. The two streams meet at the Kabaale hub in Hoima district, the starting point of the export pipeline.
Its quality is the commercially interesting part. At roughly 28 to 31 degrees API and low in sulphur, it sits in a band refiners can process without heavy upgrading.
That is what ‘sweet’ means in the name. It is a technical description, not marketing.
Why naming a crude grade is a real event
Every traded crude needs an identity before it can be priced. Buyers, assay laboratories and shipping desks all work from a named, specified blend.
Until a grade has a name and a published assay, it cannot be quoted against a benchmark or written into a term contract. Naming is the administrative step that turns a project into a commodity.
It also signals confidence about timing. Governments do not usually name a blend years before it flows.
The volumes, and what they are worth
Peak design capacity is about 190,000 barrels a day at Tilenga and about 40,000 at Kingfisher, some 230,000 barrels a day together. Peak is a design figure, not a first-year figure.
For scale, that would put Uganda well below Nigeria or Angola but comfortably into the ranks of Africa’s mid-sized producers. UNOC’s 15% stake in each project is the state’s direct exposure.
Commercial production is targeted before the end of 2026, with first flows expected around November at the earliest. This project has slipped repeatedly since commercial quantities were confirmed in 2006, so a target is a target.
The pipeline is the part that can still bite
Uganda is landlocked, so every barrel must cross Tanzania through the East African Crude Oil Pipeline to reach a tanker. The pipeline is heated along its length because the crude is waxy.
That makes the export route a single point of failure in a way it is not for coastal producers. It also makes the relationship with Tanzania a permanent commercial fact rather than a diplomatic nicety.
EACOP has faced sustained financing and legal opposition on environmental grounds, and several international banks and insurers declined to participate.
What a new grade means for buyers
A low-sulphur medium-light barrel from East Africa is a useful addition for refiners in Asia and Europe managing tighter fuel specifications. Whether it earns a premium depends on freight and on how reliably it arrives.
For Uganda the harder question is fiscal rather than geological. Oil revenue arriving in a country with no history of managing it is a governance test before it is an economic one.
Twenty years from discovery to a name
Commercial quantities were confirmed in the Albertine Graben in 2006. Two decades later the country is still waiting for its first barrel to be sold.
The delay has several causes, and they are worth separating. Uganda spent years arguing with international partners over a refinery-versus-pipeline strategy, then over tax treatment on stake transfers.
Final investment decisions on Tilenga and Kingfisher came only in 2022, alongside the pipeline. Everything since has been construction and financing.
That timeline is the useful context for any target date announced now. This is a project with a long record of slipping.
It also explains why naming the blend registers as news at all. After twenty years, an administrative step that implies imminent sales is itself a signal.
The fiscal architecture is the part still least visible to outsiders. How revenue is shared, saved and audited will matter more to Ugandans than the grade of the crude.
The financing story around EACOP is part of the commercial picture rather than a side issue. A pipeline that several major banks and insurers declined to underwrite carries a higher cost of capital, and that cost is recovered from the barrels.
Uganda and Tanzania ultimately assembled funding from a mix of Chinese, regional and specialist lenders. That changes who holds the exposure and, over time, who has influence over the project.
For a first-time producer this matters more than it would for an established one. Uganda is entering the market with a capital structure shaped by who was willing to lend rather than who offered the best terms.
None of that stops the oil flowing. It does shape how much of the revenue stays in Kampala.
