Steam injection is an increasingly common method of extracting heavy crude oil. It is considered an enhanced oil recovery (EOR) method and is the main type of thermal stimulation of oil reservoirs. There are several different forms of the technology, with the two main ones being Cyclic Steam Stimulation and Steam Flooding. Both are most

Read MoreThe upper well (injection well) works as a steam chamber and is used to continually inject steam into the ground. As temperature rises in the oil sand formation, bitumen becomes more fluid, and due to gravity, flows to the lower well (production well).
Read More2021/11/8 · An oil-burning boiler of this description with a heating surface of 42osq.ft. in the cylindrical portion and 2,58osq.ft. in the water tubes, with a steam pressure of 305.6 lb. per sq. inch, evaporated 16 lb. of water per hour per lb. of oil used.
Read MoreSteam is injected from an injection well, and the injected steam forms a steam chamber around the injection well (Bridgwater, 2003; Nabipour et al., 2007). The steam chamber is expanded toward a production well and displaces the reservoir fluid into a production well with reducing the viscosity of heavy oil ( Shafiei et al., 2013; Lake and Walsh, 2008 ).

Read Moreinjection, in-situ combustion or hot water. Reservoir depth for steam applications is limited due to heat loss associated with wells. Steam Injection can be applied to shallow reservoirs (< 1,500 m) of heavy oil deposits that cannot be produced economically by
Read MoreIn cyclic steam stimulation the same well is used for steam injection and oil production. At first, steam is injected for a period from couple of weeks to a couple of months. The introduced steam allows to heat up the oil immediately surrounding the injection well …
Read MoreClean steam is used in the pharmaceutical and healthcare industries in processes where the steam or its condensate can come into contact with a pharmaceutical or medical product and cause contamination. In such cases, steam from a conventional boiler

Read More2016/1/18 · Inconsistent steam delivery results in inconsistent heat delivery to the reservoir, interfering with the optimization of steam-injection rates, oil recovery, project economics. Various designs exist in the literature [4] [5] for handling the phase-splitting problems.
Read MoreIn addition to injection into oil wells, this steam is also used as a heat source for an MED (multi-effect distillation) water purification system. Fresh water produced by the MED system is supplied to the community for drinking water as well as to the boiler.
Read MoreIn cyclic steam stimulation the same well is used for steam injection and oil production. At first, steam is injected for a period from couple of weeks to a couple of months. The introduced steam allows to heat up the oil immediately surrounding the injection well through convective heating thus lowering its viscosity (Fig. 1).
