Figure 1

The faster rate of oil recovery per pore volume (PV) of gas injected results in an earlier cash flow and higher IRR by lowering operating costs/bo recovered– while operating at lower, immiscible pressures.

Figure 2

Remediation by CO of a swelling clay (5%)-quartz (95%) mixture damaged by a prior injection of low TDS water. Please note the increase of effective permeability from 1.8 md to 8.8 md and increase of 480%.

Figure 3

Application of the mixed gas (EORGAS) for marginally economic waterfloods having only a 1% oil cut. Please note the significant increase in additional oil recovered and the rate of recovery-at immiscible, existing waterflood pressures-as compared to pure CO₂.

Figure 4

Demonstration of the effectiveness of the CO “workhorse” to recover oil by itself and at a faster rate-and higher volume-as compared to pure CO₂, while still operating at low pressures. Also post CO injection, pure CO₂ was sequentially injected and ultimately recovered the residual oil. Thus, the compatibility of the CO and CO₂ has been demonstrated.

Figure 5

Heavy Oil Recovery, by the mixed gas (EORGAS) at existing reservoir conditions with no external heating required (80° F, 1850 psi). The CO facilitates low temperature recovery due to mobilization of the asphaltenes and associated long chain hydrocarbons to the well bore.

A novel Huff-n-Puff technology for chemically shrinking swelling clays to increase matrix permeability and oil production.

In Oklahoma, a wellbore remediation project, having ~4% montmorillonite in a clayey standstone, was treated with EORGAS by a Huff-n-Puff process. Prior to treatment the 34° API, averaged 0.4 bopd. Post treatment, the well increased to 1.1 bopd (a 2.75x), which has been maintained for the past 3 years. During the flowback (Puff period) when EORGAS was present, the well averaged >4+ bopd for ~5 days.
In US, a full-scale field project, on a conventional reservoir is in progress by an existing EORGAS licensee.
Negotiations are currently in progress for a heavy oil application (US) with another potential licensee and other Canadian heavy oil producers.
