... Abstract Cyclic solvent injection (CSI) is a promising technology for enhanced production of heavy oil in post-CHOPS (Cold Heavy Oil Production with Sand) fields. The first stage of a CSI cycle involves the injection of solvent vapour, which re-energizes the reservoir and dissolves into oil...

... Abstract Cyclic solvent injection (CSI)—a non-thermal process option for development of post-CHOPS (cold heavy oil production with sand) heavy oil reservoirs—works by dissolving a gaseous solvent, mainly Methane (CH 4 ) or Carbon Dioxide (CO 2 ), and sometimes along with Propane or Butane...

Both behaviours are consistent with the local effective stress conditions at the tip of a wormhole that lead to continuing sand failure there.

... Abstract A pressure-gradient-based sand failure criterion has been proposed and validated to quantitatively determine the sand production and then characterize the corresponding wormhole growth and its propagations during cold heavy oil production with sand (CHOPS) processes. The new sand...

... Abstract A tractable, predictive modeling approach for Cold Heavy Oil Production with Sand (CHOPS) remains a significant practical challenge. In CHOPS, instabilities of oil-sand interactions lead to formation of meso-scale structures, such as wormholes or other defects. The sand stress...

... Abstract Cold heavy oil production with sand (CHOPS) has been applied successfully in many oil fields in Canada. However, only 5% - 15% of the original oil in place (OOIP) is recovered during cold production typically. Therefore, effective follow-up techniques are of great importance. Cyclic...

... Abstract Cold Heavy Oil Production with Sand (CHOPS) is considered to be a promising method for heavy-oil recovery from unconsolidated sands, but it offers low recovery factors (~10%). Increasing recovery from such reservoirs should be achieved through post-CHOPS enhanced oil recovery (EOR...

Therefore, a radial-composite model describing the existence of foamy oil in the inner zone and an original heavy oil outer...
