... to collect the gasesgenerated by the combustion process. A horizontal production well was placednear the base of the model to collect hot crude oil and water. A total of 8experiments, 6 of dry combustion experiments and 2 of wet combustionexperiments were conducted to investigate the process parameters. 48...

... The first horizontal well in the oil sands was drilled in 1978 at Cold lake by Imperial Oil. It was drilled from the surface and has a horizontal slottedsection of 245 m total length. It served as a production well. A verticalinjection well was located over the horizontal well at a distance of 45 m fromthe...

... wellcould not correctly model steam trap control in the production well. Thediscredited well allowed steam trap control as used in field operations, and itshowed that very similar performance is predicted with dip compared to no dipassuming that both the pressure drop in the wellbore, and heat transfer...

... Abstract Large scale production of heavy oil and bitumen is possible using the steam-assisted gravity drainage process. This process involves the use of horizontal production wells combined with either horizontal or vertical injectors. One application of the process is to enhance the recovery...

... saturation zones that have mobile water present. All production wells were fractured and steam stimulated prior to the start of the steam drive portion of the project. Efforts were made to obtain heat communication between the injector and the producer wells low in the rich tar body. However, upon injection...

... by a massive inflow of sand into the production wells resulting in reduction of flow capacity. To alleviate some of these problems, a new metallic filter of high porosity was designed and field tested. It employed steel wool elastically compressed and sandwiched between an inner and outer high resistance...

... is often hampered by problems of gravity override and channelling through unproductive, high permeability streaks. These problems can reduce the pressure gradient between the injection and production wells which is one of the key forces that drive the heated oil into the production well. It is believed...
