Abstract: A well configuration for co-injection processes, wherein a horizontal producer well at the bottom of the pay is combined with injection or injection and producer wells that are vertical and above the lower horizontal production well. This well arrangement minimizes “blanket” effects by non-condensable gases.

Abstract: A variation of expanding solvent steam assisted gravity drainage (ES-SAGD) production of heavy oil wherein steam and hydrocarbon solvent are co-injected into a heavy oil reservoir and water, hydrocarbon solvent and heavy oil are produced by gravity drainage until the steam chamber is well developed or until oil recovery reaches about 20-30% of oil in place. At that time, the wells are switched to a lateral sweep using non-condensible gas (NSG) and steam co-injection, where more hydrocarbon solvent is recovered than is recovered with ES-SAGD used alone and where the cumulative steam to oil ratio is reduced over using -ES-SAGD alone.

Abstract: The present invention relates to a well configuration for co-injection processes, wherein a horizontal producer well at the bottom of the pay is combined with injection or injection and producer wells that are vertical and above the lower horizontal production well. This novel well arraignment minimizes “blanket” effects by non-condensable gases.
