Egina Crude Oil: Assay, API Gravity, Yields & Origin

API gravity: 27.3°¹
Sulphur: 0.17 wt%
Acidity (TAN): 0.22 mg KOH/g
Pour point: -21 °C
Barrels per tonne: 7.07 derived²
Standard cargo: 1,000,000 bbl³

Evidence basis: Company-reported Company-published assay, dated 4 October 2019. Crude quality varies from cargo to cargo; in any transaction the certificate of quality for the specific lifting governs, not a published assay.

Egina: quality and origin

Egina is a medium-gravity, low-sulphur deepwater crude produced about 150 km offshore through an FPSO with roughly 2.3 million barrels of storage.⁴ The TotalEnergies assay of October 2019 gives 27.3° API, 0.17% sulphur, a total acid number of 0.22 and a pour point of −21 °C.¹

An unusually gasoil-rich barrel

Egina's assay shows 60.4% by weight in the 175–400 °C gasoil cut and less than 8% total naphtha.¹ In our reading that makes it one of the most diesel-oriented crudes in West Africa, with correspondingly little gasoline-range material.

The sulphur figure public tables get wrong

The EIA table lists Egina's sulphur as 0.30%.⁵ The company assay says 0.17% and Argus's typical value is 0.165%,¹³ so we treat the higher figure as an error in transcription.

Cargo size and output

Egina trades in one-million-barrel cargoes rather than the 950,000 barrels standard for most Nigerian grades.³ Output has declined from the roughly 200 thousand b/d cited for 2020⁶ to about 50 thousand b/d in the regulator's May 2026 table.⁷

Distillation yields

Yields in wt% as published; the cut ranges overlap, so rows do not sum to 100. Source: TotalEnergies Trading, assay dated 4 October 2019.
Cut	Yield (wt%)
Light naphtha (15–80 °C)	0.9
Heavy naphtha (80–175 °C)	6.9
Kerosene (150–230 °C)	10.6
Gasoil (175–400 °C)	60.4
Residue (>375 °C)	36.9
Vacuum residue (>550 °C)	10.9

Other assay values: density 890.5 kg/m³; viscosity 39.4 cSt at 10 °C; 7.2 cSt at 50 °C; nickel 7.7 and vanadium 0.6 mg/kg.¹

How published figures compare

Publishers quote different qualities for Egina because assays are run years apart on a stream whose field mix changes, and because price-reporting agencies publish rounded "typical" values. We show the figures side by side rather than silently choosing one.

Loading, operator and output

Loading point: Egina FPSO — see the export terminal database
Operator: TotalEnergies Upstream Nigeria (operator, 24%), OML 130⁴
Producing area: Deepwater, about 150 km offshore in roughly 1,600 m of water
Status: Active
Reported output: 49.6 thousand b/d — EGINA stream, May 2026.⁷ This is production by stream, not exports; part of some streams is delivered to Nigerian refineries.
Pricing basis: A differential to Dated Brent — see how Nigerian crude is priced
Volume conversion: 7.07 barrels per tonne at this gravity (our derived figure) — the barrels-to-tonnes converter has Egina as a preset
