Three different reservoir simulators that utilize both two-phase and three-phase microemulsion phase behavior models are used to model surfactant–polymer flooding determine compare their results. Different in each simulator describe the physical of injected chemicals into reservoir, which raises need benchmark The polymer surfactant were constructed verified on a 1D scale further 3D model. Fina...

Flooding of gas diffusion electrodes (GDEs) used in electrochemical conversion CO2 to ethylene is caused by polymerization minor products. The polymer so created reduces the hydrophobicity GDE, leading initially a reduction yield and finally complete failure.

A series of experiments were carried out to study the relationship between polymer and reservoir permeability, as well as the alternating injection pattern for heterogeneous formations. The polymer molecular size (MS) was studied using dynamic light scattering. The parameters such as hydraulic radius, molecular weight (MW), concentrations and salinity were studied. The injection capacity and th...

The transport characteristics of water slugs in a bent gas channel of a polymer electrolyte membrane (PEM) fuel cell are numerically studied using the volume of fluid (VOF) method. To investigate the effects of channel cross-sectional shape in a channel flooding situation, the gas channels (GCs) with one rectangular and two trapezoidal cross sections are compared. Parametric studies are also co...

The use of water soluble polymers for enhanced oil recovery (EOR) provides an additional chance to extract between 5 to 30% of total oil in place from drilled and mature reservoirs [1]. A big number of patents, mainly from multinational companies, remark the importance of polymers for EOR [2]. The role of the polymer in the aqueous solution is to increase the viscosity of the displacement solut...

A large quantity of world’s oil reserves exists in carbonate reservoirs. Carbonate reservoirs are very sensitive to chemical enhanced oil recovery process because of containing large amount of calcite, dolomite and calcium sulfate minerals. These minerals cause major obstacles during alkali-surfactant-polymer (ASP) flooding. Alkali reacts with these minerals and form undesired precipitations wh...
