摘要： An underground reservoir is provided comprising an injection well and a production well. The production well has a horizontal section oriented generally perpendicularly to a generally linear and laterally extending, upright combustion front propagated from the injection well. The method relates to controlling location of inflow into a production well during in situ combustion. The horizontal section of the production well includes blocking agents to prevent well failure.

摘要： The present invention provides a method for accelerating start-up for SAGD-type operation by providing radio frequency heating devices inside the lateral wells that can re-heat the injected steam after losing heat energy during the initial injection. The method also extends the lateral wells such that the drilling of vertical wells can be reduced to save capital expenses.

摘要： A system and method for in situ upgrading of crude oil is provided. The system includes at least one injection well, at least two first production wells, and at least one second production well. The at least one injection well has a vertical portion and a plurality of non-vertical portions connected to the vertical portion. The at least two first production wells are preferably equi-spaced and each has a horizontal portion with a first axial direction, wherein each said horizontal portion of the first production wells is horizontally spaced apart. The at least one second production well has a horizontal portion with a second axial direction. The catalytic reactor is placed at the horizontal portion of the at least one second production well such that oil coming through the second production well will first go through the catalytic reactor for hydroprocessing.

摘要： Methods and systems relate to in situ combustion utilizing configurations of injection and production wells to facilitate the in situ combustion. The wells define vertically deviated lengths that have different orientations from one another. Further, heating processes such as resistive heating and cyclic steam stimulation may take place in one or both of the injection and production wells to precondition a reservoir prior to the in situ combustion.

摘要： Methods and apparatus relate to systems and methods of recovering oil from a formation. In operation, a steam chamber develops as a result of steam injection into the formation and the recovery of fluids including the oil through a production well. An auxiliary well spaced in a lateral direction from the production well helps ensure development of the steam chamber as desired. The auxiliary well may enable heating of the formation through establishing an electric potential between the auxiliary well and the production well or by resistive heating of material forming the auxiliary well. Further, the auxiliary well may provide a flow path for solvent or gas injection to facilitate the recovery through the production well.
