A strategic energy commodity, not a single product
Crude oil spans hundreds of distinct grades — each with its own density, sulfur profile, yield curve and benchmark pricing differential. Grade selection is fundamental to refinery procurement economics.
Crude oil is the unrefined petroleum feedstock from which all refined products — gasoline, diesel, jet fuel, naphtha, lubricants, bitumen — are derived through distillation and conversion at refineries. Its commercial value is primarily determined by two parameters: API gravity (density) and sulfur content. Lighter, sweeter crudes command price premiums because they yield more high-value products at lower processing cost. Heavier, sourer grades require more complex refinery configurations but serve essential roles as industrial and conversion feedstocks.
Atabaş Group sources crude from verified, licensed production entities and authorized export terminals. All supply chains are subject to KYC, KYB and sanctions screening before transaction progression. Every cargo is structured under a formal Sale and Purchase Agreement with independent inspection at the load port.
| Density Class | API Range | Characteristics |
|---|---|---|
| Extra Light | Above 45° | Condensate-range. Exceptional naphtha yield. |
| Light | 35° – 45° | Premium gasoline & distillate yield. Highest value class. |
| Medium | 22° – 35° | Balanced yield profile. Most widely traded globally. |
| Heavy | Below 22° | Dense, viscous. Requires conversion units. Discounted. |
| Sulfur Class | Sulfur % | Refinery Impact |
|---|---|---|
| Sweet | Below 0.5% | Low desulfurization cost. Premium over sour grades. |
| Medium Sour | 0.5% – 1.5% | Standard hydrotreating. Moderate discount to sweet. |
| Sour | Above 1.5% | High desulfurization cost. Specialized refinery units required. |
Contractual specification range by parameter
All crude oil cargoes are subject to contractual confirmation and independent inspection prior to transfer of title. Final specifications depend on grade and commercial agreement.
| Parameter | Specification Range | Test Standard | Notes |
|---|---|---|---|
| API Gravity | 20° – 45° | ASTM D287 | Grade-dependent. Higher API = lighter crude. |
| Sulfur Content | 0.1% – 4.0% m/m | ASTM D4294 | Below 0.5% = sweet; above 1.5% = sour. |
| Viscosity at 50°C | 5 – 50 mm²/s | ASTM D445 | Affects pumpability and vessel loading rate. |
| Water Content | Max 1.0% vol. | ASTM D4006 | Dehydration required above threshold. |
| Pour Point | −30°C to +30°C | ASTM D97 | Critical for cold-climate transport planning. |
| Ash Content | Max 0.1% m/m | ASTM D482 | Indicator of inorganic mineral content. |
| BS&W | Max 0.5% vol. | ASTM D4007 | Basic Sediment & Water — measured at load port. |
| Salt Content | Max 100 PTB | ASTM D3230 | Pounds per thousand barrels. Refinery limit. |

Downstream uses across five industry sectors
Crude oil is the primary feedstock for all major energy and petrochemical production industries. Refinery grade selection is driven by downstream product yield requirements.
Primary refinery feedstock for gasoline, diesel, jet fuel, fuel oil and LPG. Yield profile is grade-dependent — light sweet crudes maximize transport fuel output.
Naphtha and LPG fractions from crude distillation feed steam crackers producing ethylene, propylene and BTX aromatics — the foundation of the global chemicals industry.
Residual fuel oil and heavy crude fractions are used in power generation in markets where natural gas is limited or during peak demand periods.
Vacuum distillation fractions from suitable crude grades are processed into base oils for automotive, industrial and marine lubricant production.
Vacuum residue from heavy crude distillation is processed into bitumen and asphalt for road construction, waterproofing and industrial applications.
Crude fractions are the origin of solvents, waxes, sulfur, hydrogen and other specialty chemicals produced as co-products of the refining process.

Common questions about crude oil supply
Answers to the questions most commonly raised by refinery buyers and institutional counterparties approaching Atabaş Group for crude oil supply.
What is the minimum transaction volume for crude oil?
The minimum transaction volume for crude oil supply through Atabaş Group is 1,000,000 barrels per cargo. This reflects the standard minimum for VLCC and Suezmax vessel operations and is aligned with the minimum viable economics for refinery-to-refinery supply programs. Smaller volumes are not accommodated through our current crude trade structure.
What crude oil grades does Atabaş Group supply?
Atabaş Group can facilitate supply across a range of internationally traded grades including Brent, Urals, Bonny Light, CPC Blend, Azeri Light, Murban, Arab Light, Es Sider and others. Specific grade availability depends on verified supply access at the time of inquiry. All grades are sourced from authorized, licensed production entities and export terminals — not from informal intermediary chains.
What delivery terms are available?
Atabaş Group offers FOB (Free on Board at agreed loading port), CIF (Cost, Insurance and Freight to destination port) and CFR (Cost and Freight with buyer-arranged insurance) under Incoterms 2020. Delivery structure is defined within the commercial agreement. Vessel nomination, port scheduling and inspection coordination are managed in accordance with the agreed Incoterm.
How is crude oil quality verified?
Independent third-party inspection is conducted at the load port by SGS, Bureau Veritas or Intertek before title transfer. The inspector certifies quantity and quality against contractual specifications. Certificates of Quality (COQ), Certificates of Origin (COO) and weight certificates are issued with every cargo and are available for buyer review. No cargo is released without satisfactory inspection clearance.
What compliance procedures apply to crude oil transactions?
All crude oil transactions are subject to full KYC and KYB verification of both buyer and supply-side counterparties. Sanctions screening is conducted against OFAC, EU, UN and FATF watchlists before any engagement. Atabaş Group does not transact with sanctioned countries, listed entities, restricted financial institutions or counterparties with insufficient beneficial ownership documentation. Compliance clearance is a precondition of all supply programs.
