Prior to the implementation of CO2 injection EOR projects, the screening evaluation of candidate reservoirs will promote the economic benefits of CO2 injection. Currently, a uniform screening method for CO2 miscible flooding does not exist. Based on more than 112 successfully implemented CO2 miscible flooding reservoirs, which was referred in 2010 Worldwide EOR Survey, and CO2 miscible flooding...

Integrating a geographic information system and multi-criteria decision making methods have been lead to provide spatial multi-criteria decision making methods. In this study, the spatial potential of flooding was determined based on analytic network process and analytic hierarchy process. At first, six factors of flooding were determined as criteria. The criteria were the slope, hill-slope asp...

in this research the experimental and theoretical studies on different enhanced oil recovery (eor) techniques, i.e. water flooding (wf), gas injection (gi) and water alternating gas process (wag) were performed on specimens taken from an iranian carbonate offshore reservoir at the reservoir condition. the experimental results for each specified techniques were compared with the corresponding re...

the biqian-10 block, located in henan oilfield of sinopic, contains many thin and interbedded reservoirs, which have been operated by cyclic steam stimulation for 20 years or more. therefore, it is a challenge to implement the conventional steam flooding. in order to improve the recovery of steam flooding, urea was used to assist steam flooding. urea can decompose into co2 and nh3, which are be...
