... petroleum residence time in a reservoir, which is fundamental for prediction of biodegration rates, seal integrity (failure), and oil quality, all of which are affected by fluid mixing processes. While forward models can estimate plausible charge rates based on thermal histories, there are no field data...

...-sections show the distribution of the reservoir intervals only in the wells whereas in the interwell space the presumed distribution pattern is rather schematic and simplified ( Fig. 1 ). One distinct feature of Lemezinskoe field as a reefal build-up is lack of biodegrated oil or gas cap. drilling...

This paper presents a case study of applying a biodegrable, low IFT (interfacial tension) micellar emulsion and solvent extraction for recovering oil from highly viscous crude oil sludge, which could not be recovered by the current processes. This process yields total hydrocarbon (liquid...

This paper highlights a new generation of oil based fluid that is non-toxic and more readily biodegradable both under aerobic conditions. The fluid system is a response to the environmental concerns restricting...
