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 existence of the bottom oil–water transition zone (BTZ) greatly impairs performance conventional steam-assisted gravity drainage (SAGD) process and its mitigation measures are very limited. In order to accelerate oil production decrease Steam-to-Oil Ratio (SOR), a promising technology involving steam drive (SDGD) by placing dual-horizontal wells with high permeability in BTZ was systematica...

In this Special Issue, all aspects of fluid flow and heat transfer in geothermal applications, including the ground exchanger, conduction, convection porous media, are considered. The emphasis here is on mathematical computational conventional unconventional reservoirs, engineering, drilling enhanced oil recovery (hydraulic fracturing, steam-assisted gravity drainage (SAGD), CO2 injection, etc....

Shortand long-term ground deformation at the cyclic steam stimulation (CSS) enhanced oil recovery sites in the Cold Lake region of Alberta, Canada, was measured with RADARSAT-2 differential interferometric synthetic aperture radar (DInSAR) during 2011–2016. The interferometric processing of 84 highresolution spotlight images revealed extensive short-term ground uplift and subsidence greater tha...

It is necessary to establish effective communication between two horizontal wells during the preheating period of steam-assisted gravity-drainage (SAGD). However, time usually very long, which results in high steam consumption and CO2 emissions. There little research on effects different wellbore fluids period. The heat transfer heating characteristics fluids–water, heat-conduction oil, air–wer...
