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: Methods produce heavy oil with steam assisted gravity drainage. Such methods alternate a traditional steam injection with an injection of a steam-plus-non-condensable gas (such as CO2 or CO2-plus-diluent) mixture. The CO2/diluent mixture is soluble in bitumen, leading to a reduction in viscosity of the heavy oil. Additionally, the steam-only injection reduces the accumulation of vapor NCG along the edge of the steam chamber, leading to improved thermal efficiency.
Abstract translation: 方法用蒸汽辅助重力排水法生产重油。 这种方法将传统的蒸汽注入与注入蒸汽加不可冷凝气体（例如CO 2或CO 2加稀释剂）混合物交替。 CO2 /稀释剂混合物可溶于沥青，导致重油的粘度降低。 另外，仅蒸汽喷射减少蒸汽NCG沿着蒸汽室边缘的积聚，从而提高热效率。

Abstract: Methods and systems produce petroleum products by steam assisted gravity drainage with dual producers separated vertically and laterally from at least one injector. Placement of the producers limits temperature rise of draining fluids and hence reflux of non-condensable gases injected with steam. In particular, the fluids drain along a steam chamber boundary for recovery at positions that are not in a direct downward path from where the injector is introducing heat.

Abstract: Single well SAGD is improved by having one or more injection segments and two or more production segments between the toe end and the heel end of a flat, horizontal well. The additional injection points improve the rate of steam chamber development as well as the rate of production, as shown by simulations of a central injection segment bracketed by a pair of production segments (-P-I-P-), and by a pair of injection segments with three production segments (-P-I-P-I-P). Although the completion of the single well costs more, this configuration allows the development of thin plays that cannot be economically developed with traditional SAGD wellpairs.
