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.

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 ...

Amid the ongoing debate in the U.S. about the wisdom of banning the importation of Russian petroleum, roughly 5-10 percent of total U.S. petroleum imports (crude oil and refined products), it is ...

LONDON (Reuters) - Two of Iran's biggest OPEC rivals, Saudi Arabia and Iraq, are bagging its European oil market share by cranking up production of their lookalike crude grades before the restart of U ...

The Guyana-Suriname oil basin may hold much larger reserves than anticipated. Suriname is looking to replicate Guyana’s oil boom through 2030. Low projected breakeven prices and discoveries of light ...
