The crude oil price escalation and de-escalation formula for change in API gravity may result in payment of a higher price for a crude oil as a result of the increase in API gravity, when the ...

Crude quality as expressed in API gravity has been creeping higher the last few years. This is a problem for U.S. refiners as they invested heavily in processing heavier grades from foreign sources.

As defined by the U.S. Geological Survey (USGS), heavy oil is a type of crude oil characterized by an asphaltic, dense, viscous nature (similar to molasses), and its asphaltene (very large molecules ...

Two separate correlations for predicting the isothermal compressibility of reservoir fluids and crude oils have been developed. One correlation is based on molecular weight; the other, on API gravity.

Argentina's shale oil output hit an all-time high in September 2025, driven by record production from the Vaca Muerta ...

SINGAPORE (Reuters) - Iraq's Oil Marketing Company (SOMO) has revised the price mechanism used to compensate buyers for fluctuations in the density of its crude exports, starting with shipments in ...

EIA: higher crude density drove part of U.S. crude oil output growth last year. Texas accounted for 57% of the total production of crude oil with an API gravity between 30.1 and 40.0 degrees in the ...

ExxonMobil's strong third quarter 2025 earnings are significantly driven by rapidly growing, highly profitable production from its world-class Stabroek Block offshore oil operations in Guyana, despite ...

The United States is currently the world’s largest crude oil producer, but it still needs to import heavy varieties of oil, as most of the domestic output tends to be light crude while refineries are ...
