... Two other examples of hydrocyclones in relation to polymer flooding are ( Wang et al., 1999 ) and ( Liu et al. 2005 ). Both references relate to the Daqing oil field, China indicating that different designs of hydrocyclones could improve its efficiency. Wang showed that a dynamic hydrocyclone...

... has been evaluated through rapid emulsification tests founding that, as a general trend, the increase of the solid concentration led to more stable emulsions. The impact of the presence of polymer (Xanthan) has also been tested through bottle testing. The interaction between the solids, the polymer...

... Abstract Low-Salinity Polymer (LSP) flooding is a hybrid enhanced-oil-recovery (EOR) technique, which can improve the displacement efficiency by synergistically combining the advantages of low-salinity (LS) waterflooding and polymer-injection methods. However, comprehensive design of the LSP...

... Abstract The case studies for Polymer flood globally in heavy oil are few and far between. The low primary recovery of this field warranted an EOR scheme. The present paper discuss the challenges in designing & implementing a polymer flood project in a heavy oil field in a strong aquifer...

A Cross-Linked LCM Pill was customized in the lab prior to be mixed as follow: 34.6 ppb Cross-Link Polymer, 42 ppb Barite and 6.7 ppb Cross-Link retarder were mixed in the pill tank for expected Bottom Hole Temperature (BHT) 160 °F. The Cross-Linked...

... an area of ~105 km 2 . This paper sheds light on the successful application of a long-term polymer injectivity (LTPI) test in the SAUB reservoir as a strategic milestone towards phased commercial polymer-flooding development. The main objective of the SAUB LTPI test was to evaluate injectivity at multiple...

... Abstract Alkali Polymer (AP) is considered as enhanced oil recovery (EOR) technique for a mature field in Austria. To achieve technology qualification, different workflows have been implemented that supports risks definition and mitigations. We therefore present here the necessary steps...

The treatment consists of bullheading a water-swellable agent into the injection well along with an aqueous solution to swell the agent. The agent is a synthetic polymer capable...

... Abstract Mangala field is under polymer-flood since 2015. The polymer-flood is very successful in accelerating recovery compared to waterflood. As the flood matured, field performance indicated that part of the injected polymer was degrading in the reservoir. Lab studies and polymer samples...

...Selection of the candidate pattern(s) Abstract The Mangala Field is located in the Barmer Basin in north-west of India ( Fig. 1 ). The field has oil in-place volumes of 1.3 billion barrels, with an estimated recovery factor of 43% with polymer flood. Production began in 2009 and water...
