Paper presented at the SPE Canada Heavy Oil Conference, September 28–October 2, 2020
Paper Number: SPE-199928-MS
... It has been estimated that the amount of heavy oil and bitumen is about 6-8 trillion barrels, which accounts for more than two thirds of the worldwide crude oil resources ( Dong et al., 2019 ). More efforts have been directed to exploit and develop heavy oil and bitumen due to the increasing...

Paper Number: SPE-189727-MS
... Abstract One of the key steps towards improving the predictability of air-injection-based processes relies on the development of accurate phase behavior models of the oil. Historically, for in-situ combustion (ISC) in heavy oils and bitumens, phase behavior was often ignored, as the physical...

Paper presented at the SPE Canada Heavy Oil Technical Conference, February 15–16, 2017
Paper Number: SPE-184998-MS
... Abstract Nowadays EOR methods such as thermal techniques are widely used to recover the viscous hydrocarbons from heavy oils and bitumen reservoirs. One of the thermal methods is the Steam-Assisted Gravity Drainage (also called SAGD), which consists in injecting steam into the reservoir to melt...

Paper Number: SPE-184981-MS
... Summary Steam-assisted gravity drainage (SAGD) has been used to develop the "super heavy" oil reservoirs in PetroChina Xinjiang Oilfield Branch. These reservoirs have a very high oil viscosity that can reach more than 50,000 cp at 50°C. Moreover, owing to their continental deposit origin...

Paper Number: SPE-180699-MS
... Abstract World heavy oil and bitumen deposits contain more than twice the amount of crude compared to conventional reservoirs. Thermal production operations are used worldwide for heavy oil and bitumen production. Because of their nature, heavy oil and bitumen have a higher asphaltene content...

... in chemical EOR has not been successful economically due to high cost of surfactant and surfactant loss in the reservoir. The economic picture could be much better when this technology is applied for recovery of high TAN heavy oils which can release the required amount of surfactant (petroleum soap) in-situ...

... Abstract Electromagnetic (EM) heating holds a large potential in heavy oil recovery since it can reduce carbon emission and avoid excessive water usage, and is applicable for water hostile reservoirs such as shale oil reservoirs. Combining solvent injection and EM heating might further reduce...

The proposed CPA-EOS model has only one adjustable parameter, which decreased a lot of unnecessary computational time. This is especially important for systems containing complex materials such as bitumens and heavy oils...
