Water-in-oil (W/O) emulsions are the most common type of emulsions handled in petroleum processes. It is thought that the field emulsions are primarily stabilized by asphaltene-resin micelles and several research works have studied the stability mechanisms of asphaltene in crude emulsions....

Size DependencyIn this study, uniaxial compressive strength (UCS) of limestone rocks was estimated by indentation testing on small rock fragments. Here, the effects of rock fragment dimensions (particularly area and thickness) on indentation indices were studied. The investigation shows size...

Several sand control techniques have been used in SAGD wells in Western Canada. For most projects, slotted liners have been the sand control of choice for its economics, ease of use, and acceptable performance. Careful design of the slot geometry is crucial to maintaining...

In this Paper, UCS of limestone rock was determined by indentation testing on rock fragments. The size of the fragments was in the range of 2 to 5 mm, which is within the size range of drill cuttings. Here, scatter of the data was investigated by calculating the coefficient of variation that...

Slotted liners have been widely used in steam-assisted gravity drainage (SAGD) wells owing to their low cost and superior mechanical integrity. Multiple factors affect the performance of slotted liners, such as particle size distribution (PSD) of formation sands, aperture size, slot density,...

Airspace Flow Programs (AFPs) assign ground delays to flights in order to limit flow through capacity constrained airspace regions. AFPs have been successful in controlling traffic with reasonable delays, but a new program called the Combined Trajectory Options Program, or CTOP, is being explored...
