... extra-heavy oils can possess API as low as 4 [ 2 ]. Due to extremely high viscosity, heavy oil can only be produced with thermal recovery methods where heat is introduced to the reservoir to lower oil viscosity and make it flowable. Steam injection is one of the most common techniques for thermal...

...Steam injection Period (direction 1) Abstract Cyclic steam stimulation (CSS) is one the most effective thermal recovery methods. It is widely used as the primary thermal recovery method to recovery heavy oil fields in Middle East, Asia Pacific, North and South America. In this paper, a novel...

... would also affect the ultimate recovery (EUR). High steam injection rate results in high steam chest pressure (or temperature), and thus reduces the thermal latent heat, and thus decrease EUR. The paper has conducted a case studies for the demonstration: the Kern River Field (USA) with a long history...

The steam capacity that becomes available due to the replacement of steam with air in mature well-pairs or pads could serve new pads...

... n P . Alternatively, we can also propose a 3-factor model, where the total injection rate is broken down into water injection and steam injection rate, as it can be seen in Eq.(4) : (4) q ^ L [ t ] = k ^ q w i q w i [ t ] + k ^ q s i q s i...

... Abstract Heavy oil extraction requires heat introduction to the reservoir to enhance the mobility of oil. While steam injection is one of the most reliable thermal EOR methods for heat introduction, it has several operational, technical, economic, and environmental limitations. This study...

In 1999, the Eocene Steam Stimulation Pilot, a multi-well cyclic steam stimulation (CSS) test, was conducted to provide information regarding the applicability of steam injection to Eocene reservoirs. The pilot evaluated reservoir, production...

... Abstract A horizontal steam injection pilot project has been underway for the last four years in the Kern River heavy oil field located in the southern San Joaquin Valley of California. This pilot project was designed to address the following four prioritized learning objectives for horizontal...

... Abstract A critical design component on any steam injection project is to ensure steam containment. Loss of steam containment is not only a safety hazard, but also leads to poor well performance. Large changes in temperature have always been challenging to maintaining cement integrity not only...
