Abstract: Described herein are methods for accelerating the start-up in SAGD type processes wherein the volume between the injector and the producer is preheated utilizing open-holes drilled between wells. The recovery of hydrocarbons is also improved due to a viscous fluid drive in the open-holes during SAGD operations.

Abstract: Thermal recovery of oils is improved by capturing waste heat from a depleted steam chamber using steam plus foam and an optional gas to carry low quality steam deep into the chamber where the waste heat converts water to steam in situ. Thus, overall steam generation needs and thus costs are reduced.

Abstract translation: 通过使用蒸汽加泡沫和可选择的气体从耗尽的蒸汽室捕获废热来提高油的热回收，以将低质量的蒸汽深入到室中，其中废热将水原位转化为蒸汽。 因此，需要整体蒸汽发生，从而降低成本。
