The Application of Improved Numerical Techniques to 1-D Micellar/Polymer Flooding Simulation
… method was applied to a 1-D micellar/polymer flooding simulator. By using a semi-discrete method, the time step size can be controlled and varied to be as large as pos-sible without sacrificing accuracy. The stability limit can also be detected with this method. The method is tested …

Laboratory Investigation of Polymer-flooding, ASP-flooding, and Foam-flooding in Heavy Oil System
… because heat losses will be too severe. Water flooding is an alternative but it can only achieve a very low oil recovery due to severe viscous fingering. Hence, research into other non-thermal recovery methods is necessary. This thesis presents a laboratory-scale investigation of heavy oil …

Numerical simulation and optimisation of polymer flooding in a heterogenous reservoir : constrained versus unconstrained optimisation
Polymer flooding offers the potential to recover more oil from reservoirs but requires significant investments which necessitate a robust analysis of economic upsides and downsides. Key uncertainties in designing a polymer flood are often reservoir geology and polymer degradation. The objective of …

Simulations of subsurface multiphase flow including polymer flooding in oil reservoirs and infiltration in vadose zone
… price, the enhanced oil recovery methods such as polymer flooding to increase oil production from water flooded fields are becoming more attractive. Effective design of these processes is challenging because the polymer chemistry has a strong effect on reaction and fluid rheology, which in turn …

Rheology and Flow Behaviour of Non-Newtonian, Polymeric Fluids in Capillaric and Porous Media: Aspects Related to Polymer Flooding for Enchanced Recovery of Heavy Oil
Heavy oil reservoirs under consideration for polymer flooding typically contain greater than 85% of the original oil in place (OOIP) after primary recovery and waterflooding. Many of these fields are operated at high producing water/oil ratios (WORs) only marginally above their economic limit due …

A novel approach to upscaling reservoir simulation modelling for polymer processes
Polymer flooding is a widely employed enhanced oil recovery technique that involves injecting polymer solutions into reservoirs to improve recovery efficiency. Key mechanisms such as mobility control, polymer-rock interaction, gravity segregation, viscous crossflow, and reservoir heterogeneity …
