The oil (diluted bitumen)–water separation efficiency at steam-assisted gravity drainage (SAGD) process conditions has been evaluated in a laboratory environment by using custom-built batch setup, SAGD field fluids and commercial gas condensate as diluent. key parameters investigated are solvent amount, shear conditions, water-to-oil ratio, the presence wettability of fine solids. results demon...

A technique capable of capturing the dynamics of reservoir fluids in the proximity of production wells would provide enormous benefits to the reservoir management. In fact, monitoring can be used to develop a feedback loop between measurements and control technologies to optimize production. This paper validates the feasibility of a borehole radar tool as a permanent down-hole sensor for near-w...

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...

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...

A technique capable of capturing the dynamics of reservoir fluids in the proximity of production wells would provide enormous benefits to the reservoir management. In fact, monitoring can be used to develop a feedback loop between measurements and control technologies to optimize production. This paper examines the feasibility of a borehole radar tool for near-wellbore imaging. Modeling results...

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...
