Speak the Language of Global Energy Trade

Essential oil, gas, and energy terms for professionals trading between the US, Latin America, and Africa. This reference covers specifications, shipping, contracts, and finance.

In the corridors of US-LATAM and US-Africa energy commerce, precision in terminology is not optional — it is the difference between a profitable cargo and a stranded asset. From the Permian Basin to the offshore fields of Angola and the refineries of Mexico, every contract, bill of lading, and financing agreement rests on a shared understanding of terms that govern volume, quality, price, and risk. This glossary equips traders, logistics managers, and trade finance professionals with the definitions that matter most in cross-border oil, gas, and energy transactions.

Crude Oil & Product Specifications

API Gravity (Gravedad API) measures how heavy or light a crude oil is compared to water. The American Petroleum Institute scale is standard in US-LATAM-Africa trade: light crudes (API > 31°) like West Texas Intermediate command premiums, while heavy crudes (API < 22°) such as those from Venezuela or Mexico require specialized refining. A trader moving Angolan Girassol crude to a US Gulf Coast refinery must know the exact API gravity to price the cargo correctly.

Sulfur Content (Contenido de Azufre) is expressed as a percentage by weight. Sweet crude (less than 0.5% sulfur) is easier and cheaper to refine into gasoline and diesel. Sour crude (above 0.5%) requires more processing and typically trades at a discount. In US-LATAM trade, Mexican Maya crude (high sulfur) is often blended with lighter grades to meet refinery specifications.

Brent Crude is the global benchmark for crude oil pricing, used extensively in contracts for cargoes moving from Africa and Latin America. While West Texas Intermediate (WTI) dominates US domestic pricing, Brent is the reference for most international trades — including Nigerian, Angolan, and Brazilian crude exports.

Cargo (Cargamento) refers to a specific volume of crude oil or refined product shipped on a single vessel. Standard cargo sizes range from 500,000 barrels (Aframax) to 2 million barrels (Very Large Crude Carrier). In US-LATAM-Africa trade, the term is often used interchangeably with "parcel" in multi-grade shipments.

Gas & LNG Terminology

Liquefied Natural Gas (LNG — Gas Natural Licuado) is natural gas cooled to -162°C (-260°F) for transport by ship. LNG is the primary vehicle for intercontinental gas trade, linking US exporters (like Cheniere Energy) with buyers in Latin America and Africa. One cubic meter of LNG expands to about 600 cubic meters of gas at standard conditions.

Henry Hub is the physical pipeline hub in Louisiana that serves as the pricing benchmark for US natural gas. LNG contracts often index to Henry Hub plus a liquefaction fee. For a trader selling US LNG to a Brazilian utility, the Henry Hub price is the starting point for all negotiations.

Cargo Diversion occurs when an LNG cargo originally destined for one market is sold to another buyer mid-voyage. This is common in US-LATAM-Africa trade when price spreads shift — a cargo heading to Europe may be diverted to a higher-paying buyer in South America.

Shipping & Logistics

Bill of Lading (Conocimiento de Embarque) is the document of title for oil and gas cargoes. In US-LATAM-Africa trade, it serves three critical functions: receipt of goods, evidence of the contract of carriage, and negotiable instrument for trade finance. A clean bill of lading is essential for letter of credit transactions.

Demurrage (Estadía) is a penalty charge paid by the charterer when a vessel exceeds the agreed loading or discharge time. In oil trading, demurrage can run hundreds of thousands of dollars per day. A trader exporting US crude to a Peruvian refinery must factor in potential port delays at both ends.

Letter of Credit (Carta de Crédito) is a bank guarantee that ensures the seller receives payment once shipping documents are presented. For US oil exporters to Latin America and Africa, an irrevocable confirmed letter of credit is the standard payment mechanism, reducing counterparty risk.

Free on Board (FOB — Franco a Bordo) is an Incoterm where the seller delivers the cargo onto the vessel at the port of loading. Risk and title transfer at that point. Most US crude exports to Latin America are done FOB, meaning the buyer arranges shipping and insurance from the US Gulf Coast.

Cost, Insurance, and Freight (CIF — Costo, Seguro y Flete) is an Incoterm where the seller pays for shipping and insurance to the destination port. CIF is common in African crude sales to US refineries, where the seller retains control over logistics.

Trading & Contracts

Spot Market (Mercado al Contado) is where cargoes are traded for immediate or near-term delivery (typically within 30 days). Spot prices are volatile and reflect current supply-demand balances. Many US-LATAM-Africa crude trades are spot, especially for smaller volumes.

Term Contract (Contrato a Plazo) is a long-term agreement to buy or sell a specified volume of oil or gas over months or years. Term contracts provide stability for both parties — for example, a US LNG producer may sign a 15-year term contract with a Mexican utility.

Price Differential (Diferencial de Precio) is the discount or premium of a specific crude grade relative to a benchmark like Brent or WTI. Understanding differentials is critical: Nigerian Bonny Light typically trades at a premium to Brent, while Mexican Maya trades at a discount.

Backwardation is a market condition where futures prices are lower than spot prices, indicating current supply tightness. In US-LATAM-Africa trade, backwardation incentivizes immediate sales rather than storage.

Contango is the opposite — futures prices higher than spot — which encourages storing oil for later sale. A trader with access to US storage may buy crude now and sell a forward contract at a profit.

Risk & Finance

Force Majeure (Fuerza Mayor) is a contract clause that frees parties from liability when extraordinary events beyond their control occur — hurricanes, political unrest, or pipeline sabotage. In US-LATAM-Africa energy trade, force majeure is frequently invoked during hurricanes in the Gulf of Mexico or labor strikes at ports.

Payment Risk (Riesgo de Pago) is the danger that the buyer fails to pay for the cargo. In cross-border oil trade, payment risk is mitigated through letters of credit, prepayment requirements, or credit insurance. A US exporter selling to a new African buyer may demand 100% prepayment until trust is established.

Title Transfer (Transferencia de Título) is the legal passage of ownership from seller to buyer. In oil cargoes, title typically transfers at the vessel's manifold flange as the cargo is loaded (FOB) or at the discharge port (CIF). Clear title transfer language prevents disputes over who bears loss or damage.
