    摘要: A non-rigid carrier conveys a pump and/or the steam generator through a bore of the production tubing string to support enhanced oil recovery operations. An annular space separates the production tubing string and a wall of a wellbore intersecting a hydrocarbon-bearing subterranean formation. Using the non-rigid carrier, the steam generator is conveyed into the wellbore and operated to inject hot gases into the formation through the perforations in the casing. Afterwards, the steam generator is conveyed out of the cased wellbore and the pump is conveyed into the cased wellbore and operated to pump hydrocarbons to the surface. For cyclic injection operations, the pump may be retrieved to the surface and the steam generator may be returned into the well. The production tubing string, such as a production tubing, remains in the well while the pump and/or the steam generator are conveyed up and down the cased well. A base installed in the cased well receives either the pump or the steam generator.

    摘要: A method for recovering heavy oil in a stratum with an injection well, a production well and a steam generator. The method begins by injecting steam from the steam generator into a horizontal portion of the injection well followed by soaking the stratum with the steam from the injection well for a predetermined period of time; and producing heavy oil from the stratum with the production well.

    摘要: Methods and apparatus relate to in situ combustion. Configurations of the injection and production wells facilitate the in situ combustion. Utilizing wet combustion for some embodiments promotes heat displacement for hydrocarbon recovery with procedures in which one or more of the production and injection wells are configured with lengths deviated from vertical. In some embodiments for either dry or wet combustion, at least the production wells define intake lengths deviated from vertical and that are disposed at staged levels within a formation. Each of the productions wells during the in situ combustion allow for recovery of hydrocarbons through gravity drainage. Vertical separation between the intake lengths of the production wells enables differentiated and efficient removal of combustion gasses and the hydrocarbons.
