...-through" design allows the use of standard OTSG feed-water to produce 80% quality steam at 100 bar, matching typical EOR specifications. The key objective for the pilot was to prove that the system is able to be deployed practically and economically at scale in the region. To do this several key elements...

... EOR in the future. The industry must develop step changes in technology and integrate these new technologies in a way to create a significant financial improvement in heavy oil operations. The largest cost in any thermal operation is the cost of steam, that can amount to more than 50...

... Abstract A cyclic steam pilot has been conducted in one of Petroleum Development Oman deepest heavy oil fields. The field is considered beyond conventional and proven enhanced oil recovery (EOR) technologies. However, as the target reservoir contains several billion barrels of heavy oil...

... difference between solar EOR and solar electric power generation: thermal energy storage systems, such as molten salt, are of no value in solar EOR, as the daily ‘time of injection’ of steam does not affect the economic value of the steam. The process of thermal EOR using steam generated by variable rate...

..., but rather their anticipated effects, such as conformance improvements or formation and movement of an oil bank with increased oil saturation. Thermal EOR projects offer a clear target for cost improvement, as steam is expensive to generate. When using non-renewable energy for steam generation...

... Abstract Steam injection is a common EOR method for the recovery of heavy crude. This type of oil, or bitumen, is extremely viscous at the reservoirs standard temperature and almost immobile. As a result, steam and other fluids are injected into these reservoirs to enable the transfer of latent...

... is -realized at the same time. 2.4 Steam system integration into the power generation plant By the development of new solvents KS-1, KS-2, the regeneration energy of the solvents is substantially decreased, but a significant amount of energy is still needed. However, since the absorbent is regenerated at a low...

... the wellbore. A grid sensitivity analysis along the r-direction was completed for deciding the optimum total number blocks of 59. Abstract Introducing heat into a heavy oil reservoir is a well-known enhanced oil recovery (EOR) technique. Cyclic steam injection (CSI), also called as huff and puff, is one...

... of technologies in a DHSG could expand applications of EOR. Elements in the proposed Heavy Oil EOR include Generation of high quality steam down hole at the sand face from a gas-fired DHSG; thereby overcoming depth limitations due to wellbore heat losses Delivery of steam together with inert...

... because of the shallow depths. The areal extent of this deposit is quite large as this is countered in every well in the entire area, covering several fields ( Ref.1 ). Operating field A under EOR in the production phase with cyclic steam stimulation followed by steam flood in a cost effective...

... of the world, solar electricity is lower cost than gas-fired power generation. Solar thermal (solar steam generation) has also emerged as a promising large-scale source of energy for thermal enhanced oil recovery (EOR) operations and other thermal energy needs, with new technologies reducing land use...

... Abstract Kuwait Oil Company (KOC) is operating two Heavy Oil fields. Field A aims at production by Cyclic Steam Stimulation (CSS), followed by steam flood. Field B envisages primary recovery through cold production, followed by non-thermal Enhanced Oil Recovery (EOR). This requires drilling...

...) In the early days of steam EOR, the focus was on heavy oil and not bitumen. Two recovery processes using vertical well geometries were used; steam flooding, where a steam injector would heat and drive oil to a producer well and cyclic steam stimulation, where a single vertical well would inject steam, followed...

These wells are the primary method for energy delivery to the reservoir and are critical to the successful...

Figure 9 depicts the life cycle of the of the steam injection EOR operation with two periods, first the preflood with single well operations under CSS and then SF using dedicated injection wells and producers arranged in patterns. Oil rate will vary during CSS cycles...

... additional heat for EOR. Heat loss reduction. Because steam is produced in-situ, either downhole or in the reservoir, no waste of heat occurs. Typically, most heat losses happen on surface lines and wellbore during steam injection from the surface, accounting for approximately 32% of the heat loss...

... Circulation Another promising development is using solar energy for thermal EOR for small onshore heavy oil fields ( Testa et al. 2015 ). Such an application is attractive for isolated small fields where steam flooding is not economical or practical. As shown in Fig. 3 , Testa et al (2015...
