Comprehensive evaluation of a novel EOR method-coupling low salinity water flooding and preformed particle gel to enhance oil recovery in fractured reservoirs
<p>"Excess water production in oil fields is becoming a challenging economic and environmental problem as more reservoirs are maturing. Water channeling, one of the primary reservoir conformance problems, is caused by reservoir heterogeneities that lead to the development of high-permeability …

Synthesis and comprehensive studies of nanogels for enhanced oil recovery
… light scattering. The ability of nanogels in oil-water interfacial tension (IFT) reduction and oil-in-water (o/w) emulsion stabilization was studied at various nanogel concentrations, temperatures, and salinities. Moreover, nanogels showed an electro-interaction controlled adsorption on the rock …

Waterflood monitoring using borehole self-potential data
… is developed to follow the evolution of an oil-water encroachment front over time during the water flooding of an oil reservoir. I simulate borehole electric potentials associated with a two-phase flow between two wells in a heterogeneous reservoir. The flow of the water phase generates a source …

Laboratory Investigation of Polymer-flooding, ASP-flooding, and Foam-flooding in Heavy Oil System
… thin pay 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 …

Determination of the velocity of sound in reservoir fluids using an equation of state
… oil recovery methods such as Gas Injection, Water Flooding, CO2 Injection, in-situ Combustion, Water Alternative Gas injection (WAG) and so on have similar effects. Variation of these properties can lead to changes in the velocity of sound in subsurface layers. On the other hand, any change …

Numerical simulation of multi-scale transport processes and reactions in pem fuel cells using two-phase models
… approach utilized the two-phase models involving water phase change for PEM fuel cells i.e. two-phase current (solid and membrane), two-phase flow (gas and liquid water) and two-phase temperature (fluid and solid). The catalyst layer has been modeled using the microscale agglomerate approach where …
