Paper Number: SPE-200057-MS
... efficiency increases when the injected gas is near-miscible or miscible with the oil. In addition to nitrogen and hydrocarbon gas projects, CO 2 -EOR has been the dominant gas EOR process. Gas-based EOR has been implemented in both mature and waterflooded carbonate reservoirs. In this paper, we present...

... as a mature waterflood, with oil production having peaked in 2011. To increase the recovery factor, a tertiary oil recovery technique (ASP) was selected. A confined five spot well pattern was chosen for conducting the ASP field trial. Due to low remaining oil saturation after the waterflood (executed also...

... the significance of mobility control during the crucial phases of the LTG flooding. The coreflood results emphasized the significance of the injection of gas, even at lower foam quality, for the maintenance of mobility control. Ultimate oil recovery of over 60% (residual oil post waterflood) was achieved, even...

... that ASP can recover more than 90% of the oil remaining after waterflood resulting in remaining oil saturation below 5%. Simulation studies showed that ASP can potentially increase the field recovery factor by more than 20% over waterflood or 10% over polymer flood. A successful ASP single-well tracer test...

... technology make it a suitable saturation monitoring tool for fields applying chemical enhanced oil recovery (EOR). The pilot was executed with several phases, starting with pre-ASP waterflooding. This was followed by ASP slug injection, which, in turn, was followed by polymer chase and, ultimately, by chase...

Simplified one- and two-dimensional models, in which aqueous phase viscosity varied as a function of polymer concentration, were used to simulate the behavior of polymer floods and waterfloods...

Paper Number: SPE-129545-MS
... Abstract Current paradigms and regulatory mandates implicitly assume that waterflood reservoir management practices successful in light oils can be extended unmodified to heavier oils. In particular, complete voidage replacement is considered optimal irrespective of oil chemistry; furthermore...
