Cyclic steam stimulation (CSS) is one of the commonly used thermal extraction methods for heavy oil and bitumen. However, CSS is still daunted by the lower oil recovery factor compared with other thermal recovery methods, such as steam-assisted gravity drainage (SAGD). Nano-metal particles, due...

Emulsion flooding and heavy oil recovery by in-situ emulsion formation have been reported to show great potential in enhancing heavy oil recovery. Emulsion stability is the key issue controlling the success of this process; conventionally, surfactants were used to facilitate emulsification and...

During the production of gas condensate from a reservoir, a gas condensate bank may be formed in the near-wellbore region, leading to reduced long-term productivity. The major existing remedial methods for removing the condensate bank include cyclic gas injection, solvent injection, wettability...

Geohazards threaten human’s well-being in many different ways. Landslide, as a common geohazard in both natural and anthropogenic man-made features all around the world, generally, damage many infrastructures, nature balance, animal habitat and cause even loss of lives for many creatures as well...

River ice processes are among the most important subjects of study for hydrotechnical engineers in cold regions. This is because extremes of both minimum flow (impacting fish habitat and the concentration and transport of pollutants) and maximum water levels (impacting channel geomorphology and...

Unsaturated soil property functions are necessary for numerical modeling of geotechnical engineering problems including transient seepage or contaminant transport involving unsaturated soils such as tailings or mine wastes. The accuracy of the input of material properties significantly influences...

Estimating costs for construction projects is a complex and often uncertain process. Given the inherent uncertainty of estimating and the unique risk profile of each construction project, many owners use cost uncertainty analysis to understand a project’s range of potential costs. Since results...
