Uganda Launches New Crude Grade as First Oil Exports Near

Uganda is poised to enter the oil export market with its new Pearl Sweet crude grade, a blend with low sulfur content and high wax content. This new grade is expected to generate significant revenue for the landlocked nation's economy. However, the high wax content of Pearl Sweet requires heating throughout the production process, adding costs and limiting the number of potential buyers.

The oil reserves are located near Lake Albert in the Albertine Graben Basin, with ownership shared between TotalEnergies, China's CNOOC, and Uganda's UNOC. TotalEnergies-operated Tilenga field, with an estimated 1.2 billion barrels of recoverable resources, is expected to produce 190,000 barrels per day (b/d), while the CNOOC-operated Kingfisher field, with around 270 million barrels, targets 40,000 b/d.

The two fields' output will be blended at the shared Kabaale facilities in Hoima. Uganda initially planned to start production in June 2026, but production deadlines have slipped, and officials now expect Kingfisher to begin in December at 25,000 b/d, followed by Tilenga in the first quarter of 2027. The Pearl Sweet crude grade has a sulfur content of approximately 0.16% and an API gravity range of 27-28 degrees, but it is exceptionally waxy, giving it a disadvantage with a pour point of roughly 39 degrees Celsius.

This requires heating through the pipeline, terminal tanks, transfer systems, and tanker voyage, posing challenges for Uganda's landlocked position and requiring uninterrupted electricity. The planned East African Crude Oil Pipeline (EACOP) will stretch 1,443 kilometers, with around 20% running through Uganda, and will require 43 MW of power, equivalent to 2% of Uganda and Tanzania's combined power production capacity.

The transportation of the crude to the Tanzanian coast alone is expected to cost $1,213 per barrel, excluding shipping expenses. While a domestic refinery could eventually absorb around a quarter of plateau production, it remains at an early stage, and the first buyer remains undisclosed. Pearl Sweet's low sulfur content and high wax content present commercial challenges, including the need for heating and transportation, making it difficult for refiners to justify the costs.

Marine fuels offer a potential outlet, as Pearl Sweet could appeal to refiners producing very low sulfur fuel oil or low-sulfur petroleum coke. However, environmental concerns and the need for coordinated construction, power supply, and export logistics create additional difficulties for Uganda's oil exports.
