Numerical investigation of polymer injection effects on geomechanical reservoir properties during enhanced oil recovery
Polymer injection is an enhanced oil recovery method based on the viscosity increase of the injected aqueous phase to control its mobility. The changes in mobility could affect the pore pressure distribution within the reservoir. The objective of this research work is investigating the effects of …

Hall plot analysis for horizontal well injectivity
… formation damage and/or stimulation diagnosis, polymer injection, and gas injection. It has proved to be a simple, inexpensive, and effective way to diagnose changes in injectivity. However, such applications are limited to vertical wells. This study proposes a new formulation of the Hall plot …

Método de decomposição de domínios de múltiplos passos de tempo de Dirichlet-Neumann aplicado à injeção de polímeros em meios porosos
… and computational model for injecting polymer solutions into porous media, efficiently coupling the process in the near-well region and the reservoir. For the mathematical model, in addition to the single-phase flow and transport equations, we postulate closure relationships for the …

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 …

Digital Rock: Understanding the mechanism of Enhanced Oil Recovery (EOR) Core Floods
… the oil and water behaviour during brine and polymer core flooding. The first step for the analysis of the physical phenomena was the detection of velocities lower than 10 ft d-1 using Magnetic Resonance Imaging (MRI). For that reason, an optimisation toolbox, which uses the relaxation times …
