Abstract The instability at the interface between two parallel flows of immiscible liquids through a uniform planar pore is studied by using linear stability analysis. A characteristic equation determines growth rate versus wavenumber, and conditions are determined. governed dimensionless group relating ratio gravity to interfacial tension. Interfacial tension has stabilizing effect resisting d...

It is widely considered that the continued development and production of Alberta’s oil sands deposits is on track to be the fastest growing source of greenhouse gas (GHG) emissions in Canada over the next few decades. As recent developments suggest, failure to address the issue of GHG emissions growth might jeopardize the potential for sustained expansion of oil sands operations in Alberta. Wit...

The high recovery performance of steam-assisted gravity drainage (SAGD) makes it a popular option for heavy oil resources. Currently, most the reservoirs developed by SAGD in China are late development phase, with energy consumption due to reduced thermal ef?ciency. use wind-down processes involving CO2 combination steam is considered as viable alternative limit consumption, and also reduce amo...

The solvent–steam assisted gravity drainage is an oil recovery process that combines the advantages of thermal and miscible effects, it has been successfully tested, especially in Canada, where many heavy reservoirs are located. This method uses two parallel horizontal wells drilled one above other, upper injects steam solvent lower produces oil. not applied yet Brazil, there reservoirs, northe...

The required steam for steam-assisted gravity drainage (SAGD) oil sands operations is generated using a once-through generator (OTSG) that fed with relatively poor quality process water. Industries have reported possible solid particle erosion-related failure in the OTSG boiler tubes because of transport precipitated dense inorganic particles. However, presence other damage mechanisms, e.g. cor...

Standing at 2.5 trillion barrels, Canada has the largest portion of the world’s ultra-heavy oil and bitumen resources. While shallow heavy oil reserves are extracted from pit mines, deeper reserves can only be extracted through wells. Production requires Steam Assisted Gravity Drainage (SAGD) and Cyclic Steam Simulation (CSS) methods. The optimal placement of wells defines the propagation of st...

Based on a recently published theoretical model, in this work we experimentally studied the problem of gravity water drainage due to continuous steam injection into an elliptical porous chamber made glass beads and embedded metallic, quasi-2D, massive cold slab. This configuration mimics process condensation for given time period during growth stage steam-assisted (SAGD) process, method used re...
