Petroleum-refinery term for combustible, viscous or semiliquid bottoms product from crude oil distillation; used in adhesives, roofing compounds, asphalt manufacture, low-grade fuel oils, and sealants. Also known as liquid asphalt; resid; residuum; tailings.

Residual oil refers to the crude oil remaining in the pores within the flooding area in the flooding process and is usually dispersed.
Laboratory studies have shown that residual oil can be recovered if the displacing phase causes viscous forces acting on trapped residual oil blobs to exceed the capillary retaining forces.
It can reflect the pore size distribution and the fluid volume in different pores, which can quantitatively calculate the displacement efficiency and residual oil in different pore size during water flooding oil.
The numerical simulation results were carried out, the remaining oil saturation were subtracted from the residual oil saturation (Fu et al., 2010), and the residual oil reserves were calculated using the formula of reserves calculation (Fig.
Residual oil witnessed a production surge of 5.8 per cent, with output rising to 17,665,300 bbl compared to 16,704,000 bbl a year ago.

With regard to this, first the surfactant washing alone and the solvent extraction alone were conducted in this study, to determine optimum process conditions and residual oil rate for surfactant washing, and the best-performing organic solvent for solvent extraction.
Other advantages of synthetic oils are their lower volatility, which results in lower oil carry over and residual oil content, especially at high temperatures, and a better viscosity-temperature-behaviour.
In most cases, a certain amount of residual oil content cannot be entirely avoided in standard applications.
The affected soil will be removed from the site and residual oil will be burned off.
Entrepreneurs from Russia, the UAE and Panama purchased straight-run gasoline, residual oil and polypropylene produced by the Turkmenbashi Complex of Oil Refineries.
