... Abstract Non-condensable gas assisted steam, being recognized as a promising technique in enhanced heavy oil recovery, has been successfully employed in oilfield for many years. Nevertheless, the displacing mechanism of this technology is complicated and has not been thoroughly understood...

... in 2017. In this work, an analysis is conducted based on the existing literature and an internal simulation study to understand the mechanisms that affect the simulation response of NCG co-injection in SAGD. State of the art Abstract When non condensable gases (NCGs) are co-injected...

... 15 years with improved recovery. High mobility ratio waterflood (HMRWF) behavior and associated key production mechanisms obtained from detailed field data analysis and dynamic modeling are presented. A novel and unique infill configuration is also proposed to further improve recovery in this high...

.... The solvent and bitumen are single component hydrocarbons; hence, no heavy phase precipitates and deposits upon mixing of solvent and bitumen. There is no volume change (shrinkage or expansion) upon mixing of solvent and bitumen. The heat transfer is governed by conduction. The mass transfer mechanism...

... Abstract The aim of this work is to evaluate the micro-displacement mechanisms associated with heavy oil recovery by water and chemical flooding in a non-linear system (2D Model). To evaluate the effect of sweep efficiency improvements with no local pore level trapping of fluids, a 2D neutral...

The improved oil recovery mechanisms for hybrid methods are experimentally studied through physicochemical characterization of ultra-heavy oil, viscosity reducer, CO2, and steam multisystem mixtures...

... Abstract Effective communication between the injector and producer with a reasonable conformance during SAGD start-up phase is crucial for the success of SAGD conversion and the following ramp-up phase. The start-up operation normally relies on heat conduction mechanism to establish heat...

.... Despite the high viscosities, strong historical production is as a result in part to good permeability, and to the foamy solution gas drive mechanism. The foamy solution gas drive has the effect of both lightening the combined oil/gas/water emulsion and providing the necessary drive mechanism to mobilize...

In situ emulsion generation is thus another active mechanism that is involved as a result of surfactants presence. Due to the above properties, steam movement is hindered, and gravity override is consequently limited...
