Witryna9 lip 2024 · Miscible flooding showed optimum recovery of 32% with a better mobility ratio and delayed gas breakthrough, while near miscible was only recovered 23%. For the interfacial tension in the miscible displacement, the fluid properties and phase behavior relationships between \(\hbox {CO}_{2}\) and condensate were stated to be … Witryna14 gru 2009 · The CO 2 flooding is a proven enhanced oil recovery technique to obtain high oil recovery from complicated formations and can be applied to various types of oil reservoirs. It can be injected as immiscible or miscible flooding but immiscible flooding is less effective than miscible flooding. Two types of miscibility can occur: …
WitrynaAbstract The gases used for flooding a reservoir - hydrocarbons, carbon dioxide and nitrogen — are injected in conditions varying from immiscibility to full miscibility. The high mobility of gas is always a problem, and difficulties are exacerbated by miscibility: the maximum stable rate is reduced below the immiscible critical rate, and the ...

Witrynamethods – chemical, thermal, miscible, and immiscible gas flooding – as well as microbial means of increasing recovery of the remaining oil (Planckaert, 2005). Over the past 40 years, polymer flooding has been carried out in marginal oil fields and has proved to be successful in many cases. Polymer flooding operates on the principle of WitrynaImmiscible gas flooding recoveries are less on average, around 6% OOIP. Although recovery by gas flooding is very economic at these levels, 55% OOIP still remains on average postmiscible gas flooding assuming 65% OOIP prior to gas flooding. The significant amount of oil that remains is largely the result of gas channeling through …
WitrynaLow salinity water injection (LSWI) is considered to be more cost-effective and has less environmental impacts over conventional chemical Enhanced Oil Recovery (EOR) methods. CO2 Water-Alternating-Gas (WAG) injection is also a leading EOR flooding process. The hybrid EOR method, CO2 low salinity (LS) WAG injection, which …
