Optimum Polymer Concentration in EOR

Laboratory Study on EOR in Offshore Oilfields by Variable Concentrations Polymer Flooding

Results: The experimental results showed that the recovery of variable concentrations polymer flooding was higher than that of constant concentration polymer flooding, under conditions of same total amount of polymer and similar water flooding recovery. Its sweep efficiency and displacement efficiency were also significantly higher than those of constant concentration polymer flooding. Moreover...

Recent Advances in Surfactant EOR

eor-1 and eor-2 are required for cell-specific apoptotic death in C. elegans.

Programmed cell death occurs in every multicellular organism and in diverse cell types yet the genetic controls that define which cells will live and which will die remain poorly understood. During development of the nematode Caenorhabditis elegans, the coordinated activity of four gene products, EGL-1, CED-9, CED-4 and CED-3, results in the death of essentially all cells fated to die. To ident...

Emulsion Formation for EOR Applications

In this study, the oil recovery potential of Smart Water in the Danish sector of the North Sea chalk reservoirs was investigated. A series of flooding experiments were conducted at reservoir conditions, and a spontaneous imbibition test was carried out at reservoir temperature. Reservoir cores were used along with crude oil samples from the North Sea and representative synthetic formation water...

CO2 EOR and Storage in Oil Reservoirs

CO2 EOR and Storage in Oil Reservoirs — CO2 injection into tertiary oil reservoirs has been widely accepted as an effective technique for enhanced oil recovery (EOR), and has been used by the oil industry for over 40 years. Concerns over greenhouse gas emissions are leading to the investigation and realisation of its potential as a carbon storage method in recent years. With the right reservoir...
