... the recovery of heavy oil reserves, such as those of Western Canada, has not been given enough attention due to immiscible nature of the mixture of CO 2 and these heavy oil resources. Many heavy oil reservoirs in Western Canada have been under waterflooding where oil is produced at very high water-oilratios...

..., and will give the oil industry a new option for improving oil recovery from heavy oil reservoirs. Introduction Recently, there has been growing interest in this technique for heavy oil reservoirs. At the end of economical life of primary production, waterflooding is performed as a secondary recovery process...

... Abstract Some of heavy oil reservoirs under solution gas drive show abnormally high final recoveries. One of the mechanisms to explain these phenomena is the foamy oil flow effect which occurs under a certain combination of capillary, viscous and gravity forces. It has been studied extensively...

... this feasibility study show a promising future for some technologies in Iranian heavy oil reservoirs. However, final selection of the most appropriate production technologies requires more detailed reservoir evaluation and technical screening. A complementary research program is recommended for the next stage...

... and stay at this level for a couple of decades. Recovery of heavy oil reservoir with wells is a challenge due to low API gravities (6 °-25 °), high viscosity (100cp-1000cp)-particularly in the presence of water. For example, the recovery factor from a heavy oil reservoir with bottom water in the H.K...

.... This is a pre-print and subject to correction. Abstract Foamy oil flow, a phenomenon associated with primary production of heavy oil under solution gas drive, is a widely accepted explanation for the high recovery factors observed in some heavy oil reservoirs. A number of theoretical, experimental and field studies...

.... This work looks at one such scenario where CO2 is injected prior to steam flooding in a heavy oil reservoir. Field applications have established that CO2 can be an efficient oil-displacing agent for both heavy and light oils as long as they are mobile at reservoir conditions. Using steam with horizontal...

... Abstract One of the important mechanisms in the primary production of heavy oil reservoirs under solution gas drive is the foamy oil flow effect. This form of flow occurs only under certain combinations of capillary, viscous and gravity forces. Several studies have been carried out to examine...

... Abstract In-situ combustion (ISC) has long been viewed as a low cost means to input thermal and driving energies into petroleum formations, and could be used to enhance oil recovery from both light and heavy oil reservoirs. However, field trials of ISC processes, in the past half a century...

... Abstract The favourable behaviour of heavy oil reservoirs under solution-gas drive has intrigued the oil industry for long. Many mechanistic models have been proposed to explain this behaviour. It is believed that the flow in heavy oil reservoir is quite complex and cannot be represented...

... Abstract In western Canada, many heavy oil reservoirs are underlain by thick bottom water. Very few of these reservoirs are commercially exploitable by conventional cold production or thermal technologies because of the high water mobility. The water zone could act as a strong water source...
