VG grades are known by the Indian government as the preferred type of bitumen for road construction. In 1991, the Bureau of Indian Standards adopted a new grading method for bitumen, named viscosity ...

The efficient recovery of bitumen, a highly viscous form of crude oil, poses significant technical and economic challenges. In recent years, researchers have developed advanced experimental techniques ...

Solvents are used to increase production and reduce steam-to-oil ratio in steam-assisted gravity drainage (SAGD). Variations of SAGD that use solvents, such as expanding solvent (ES) SAGD or ...

Conclusion The temperature dependence of a lubricant is one of the most important factors in determining its efficacy. Using a Bohlin rheometer, the viscosity can be accurately measured over a wide ...

A recent study used various gas oils and blends with residual heavy oils in order to evaluate the predictability of four different correlations. The gas oils differed substantially in their ...

AC is typically obtained as a residue from the crude oil refining process or natural sources. It has a semi-solid or solid consistency at ambient temperatures and is used as an aggregate binding ...

Greenvale Energy is on the path towards a commercial bitumen product after testwork at the Alpha project in Queensland recorded the highest conversion to date. GRV’s latest testwork shows company ...
