Deasphalting bitumen using paraffinic solvent
injection is a commonly used technique to reduce both its viscosity
and density and ease its flow through pipelines. Common modeling
approaches for asphaltene precipitation ...
Predicting asphaltene onset pressure (AOP) and bubble point pressure (Pb) is essential for optimization of gas
injection for enhanced oil recovery. Pressure-Volume-Temperature or PVT studies along with equations of state ...

A novel approach to improve viscous and viscoelastic
properties by exploiting the pH and salinity sensitivity of HPAM
polymer is proposed in this paper. Polymer flooding is a welldeveloped
and effective enhanced oil ...
Resource estimation is the main and primary step in the development of a mining project. Principally, it is
necessary to first identify the geological domains through boreholes, model them at unsampled locations, and
then ...

The uniaxial compressive strength is a very important parameter in mine design. For weak
rocks such as coal, it is particularly difficult to obtain cores for mechanical testing. Especially for the weak rocks, another ...
The wear of cutting tools is critical for any engineering applications dealing with mechanical
rock excavations, as it directly affects the cost and time of project completion as well as the utilization
rate of excavators ...
