CRUDE OIL TESTING SERVICES
Accurate Crude Oil Analysis for Confident Trading & Refining Decisions
Every crude cargo is different. Our ISO/IEC 17025 accredited labs deliver precise, defensible data on quality, composition and contaminants — helping producers, traders, refineries and inspection agencies minimize risk, optimize pricing and ensure seamless acceptance worldwide.
Crude quality impacts refinery yield and pricing. Impurities like sulfur, water, salts and metals cause corrosion and catalyst poisoning. We report TAN, RVP, pour point, wax, asphaltenes, CCR and full distillation curve.

Crude Oil Testing – Frequently Asked Questions
Every crude cargo is different. Here are expert answers from our ISO/IEC 17025 accredited labs to help producers, traders, refineries and inspection agencies make confident decisions.
Crude oil testing is a laboratory analysis that determines the quality, composition, and contaminants of crude oil. At Accredited Test Labs, we test crude as per ISO/IEC 17025, ASTM and IP methods to help producers, traders, refineries, and inspection agencies verify cargo quality, determine refinery yield, calculate accurate pricing, and prevent issues like corrosion and catalyst poisoning.
Our complete quality profile includes: Specific Gravity / API @ 15.56°C, Total Sulphur, H2S, BS&W, Water Content, Salt Content, Viscosity @ 37.7°C & 50°C, Pour Point, TAN (Total Acid Number), RVP, Ash, Asphaltenes, Wax Content, CCR, Heat Value, and trace metals Ni, V, Na, and Pb with full distillation curve. This covers physical properties, contaminants and yield data.
Assay Slate 15°C–375°C: Full True Boiling Point (TBP) curve, fraction yields, and metals analysis.
Full Assay Model: Complete yield data for LPG, Naphtha, Kerosene, Gasoil, VGO, and Vacuum Residue. This data is essential for refinery LP models, valuation, and trading decisions and is provided with individual fractions.

Our services are used by: Crude Producers, Traders & Brokers, Refineries, Oil Terminals, IFIA Inspection Agencies, and Shipping Companies. We help them ensure regional compliance, optimize refinery yields, and negotiate fair pricing with reliable, fast reporting.
Crude quality directly impacts refinery yield and market value. Impurities like sulfur, water, salts, TAN and metals (Ni, V, Na, Pb) cause corrosion and catalyst poisoning. High wax, asphaltenes and CCR lower valuable product yields. Tests like TAN, RVP, pour point, wax and asphaltenes predict these risks before processing.
We offer Fast Turnaround with rapid accredited reporting and priority slots are available for urgent cargoes. Our global lab network ensures samples are tested close to origin or destination to minimize delays in trading and vessel acceptance worldwide.
