On the night of Dec. 15, 2024, two Russian oil tankers, Volgoneft-212 and Volgoneft-239, sank in the Kerch Strait, a narrow ...

Heavy oil recovery is a critical area of research in the oil and gas industry, focusing on methods to extract viscous and dense oil that is difficult to produce using conventional techniques.

As Aliyev and other chemists note, oilmen usually pump hot water vapor into wells to extract heavy grades of oil with high viscosity. It warms up layers of oil-bearing rocks, as a result of which ...

which can significantly reduce the viscosity of heavy oil, making it easier to extract. Recent research has focused on optimizing this technique through various models and experimental studies ...

Petrobras is working towards a July 2013 startup date for the platform, which will work in the Petrobras and Chevron-led Papa Terra heavy-oil project in Brazil's Campos Basin post-salt reservoirs.

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 ...

Exploration Heavy oils are frequently found at the margins of geologic basins, according to the USGS, and are assumed to be residue from formerly light oil that has lost its light molecular weight ...

Sulphuric acid is typically injected into the aquifer rock that contains the uranium to dissolve it. The mine then pumps out the aquifer water and removes the uranium. The process repeats until ...
