Low Salinity Water (LSW) and Alkaline-Surfactant-Polymer (ASP) flooding are emerging enhanced oil recovery methods that help recover from the reservoir after primary secondary processes. Experimental studies on LSW ASP have indicated potential in additional recovery. In this paper, numerical simulation was performed to study combined effects of flooding. A heterogenous initially saturated with ...

Recent developments in water-soluble hydrophobically associating polymers are examined with particular emphasis on their use for oilfield applications. These polymers have potential for use in EOR, acidizing, drilling fluids, completion fluids and profile modification. They have also been reported to selectively reduce water permeability in sandstones, and have been used as drag-reducing agents...

Implementation of waterflooding sometimes cannot increase oil recovery effectively and requires additional methods to recovery. Polymer flooding is a common chemical EOR method that has been implemented in the last few decades provides good effectiveness increasing can reduce amount injection fluid injected into reservoir. Seeing success polymer recovery, it necessary know parameters influence ...

The polymer flooding of ordinary heavy oil reservoirs in Bohai Sea can improve the crude recovery by advancing injection time flooding. better is, higher enhanced and greater income is. Based on Oilfield, application system was characterized laboratory, then experiments were carried out at different times using one-dimensional core model. results show that: 1) AP-P4 establish good mobility cont...
