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...

Numerical Modeling of Thermal EOR: Comprehensive Coupling of an AMR-Based Model of Thermal Fluid Flow and Geomechanics — Modeling Steam Assisted Gravity Drainage (SAGD) can involve significant CPU (Central Processing Unit) time when both thermal fluid flow and geomechanics are coupled in order to take into account variations of permeability and porosity inside the reservoir due to stress change...

Résumé — Analyse de la récupération d'huile lourde par procédé thermique dans une barre de méandre : du modèle géologique à la modélisation de réservoir — Ce travail vise à évaluer l’impact des hétérogénéités d’un réservoir pétrolier sur la récupération d’huiles lourdes par le processus de Steam Assisted Gravity Drainage (SAGD) en utilisant des modèles numériques appliqués à un modèle réservoir...

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...

Zhong18 wellblock of Fengcheng oilfield developed with low permeability interlayer and had strong heterogeneity, which caused steam chamber conventional assisted gravity drainage (SAGD) process cannot extend lengthwise continuously serious heat loss. To address this problem, a method acid fracturing SAGD is proposed to enhance the oil improve recovery. Based on herringbone well being used in we...

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...
