... wormhole growth and its propagations during cold heavy oil production with sand (CHOPS) processes. The new sand failure criterion was firstly developed at a pore-scale by analyzing the mechanical balance around a throat. To simplify the mechanical analysis, a pseudo-interaction force between a failed...

... Research Council. The project was in support of a cyclic solvent injection (CSI) field pilot in the Lloydminster region of Saskatchewan that was evaluating the potential of CSI to exploit reservoirs following cold heavy oil production with sand (CHOPS). History matches were performed for two Edam CHOPS...

... Abstract CHOPS (Cold Heavy Oil Production with Sand) is a primary production recovery method used in the Western Canadian Lloydminster heavy oil region which contains about 3 billion m 3 of heavy oil. It increases heavy oil production rates by creating high permeability channels...
