Post-CHOPS EOR Methods – The Role of Wormholes

Heavy Oil Oil Sands Tight Oil & Gas


Cold heavy oil production with sand (CHOPS) is a non-thermal process that produces oil from unconsolidated sand reservoirs by co-producing sand, oil, water and gas. A characteristic of this process is the sand production leaves behind conduits of higher porosity and permeability within the reservoirs. These conduits are called “wormholes” and are thought to have an open channel surrounded by looser, dilated sand.

What effect do these wormholes have on post-CHOPS enhanced oil recovery methods? Can they assist or hinder the application of these processes? What do we know, and what do we need to know for the successful application and wide-spread deployment of post-CHOPS methods?

Four processes will be reviewed: cyclic solvent injection (CSI), submerged combustion vaporization (SCV), in situ combustion (ISC) and alkali metal silicide technology. CHOPS wells leave behind ~90% of the original oil in place, and currently there are more than 10,000 suspended CHOPS wells in western Canada. This is a super-prize waiting for the right EOR technologies to be developed, piloted and commercially deployed.
