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....

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...

Recently, in a previous study, we experimentally showed the existence of an optimal injected steam mass flow rate, per unit length, ϕopt, which produces maximal recovery condensate preformed chamber with elliptical cross section horizontal semi-major axis. Mutatis mutandis, this work, present experimental studies chambers: one and other circular. In both cases, also found unique values. These c...

Steam-Assistant-Gravity-Drainage (SAGD) has become one of the most commonly used thermal recovery processes to extract heavy oil from oil sand reservoirs, especially in Northern Alberta, Canada. However, due to geological history, interbedded shales (IBS) in the reservoir act as barriers due to their low permeability and as such hinder the progression of the steam chamber. Cap-rock integrity al...

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...

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...
