As the easy-to-access and easy-to-produce hydrocarbon resources have been depleted over the last century, more and more difficult wells remain. Also, as global hydrocarbon demand is continuously growing, meeting this demand requires development of more advanced recovery procedures, often referred to in industry as complex recovery completions and production techniques. These techniques include, for example, Steam Assisted Gravity Drainage, Thermal Assisted Gravity Drainage, Toe to Heel Air Injection, Vaporized Hydrocarbon Solvent production and Fire Flooding. Such techniques address the mobility problem of the heavy oil wells by thermally and/or chemically altering the viscosity of the bitumen to allow for easy extraction. |
