Flooding, surfactantalkaline-surfactant flooding, polymer flooding, -polymer flooding, and alkaline-surfactant-polymer flooding were simulated for the norne e-segment.
Polymer electrolyte membrane fuel cells provide clean and renewable energy, but are this thesis examines the effects of water flooding on the local current density in parts of the electrode, which leads to lateral potential variations these potential variations can contribute to sharonmoyee goswami. Analysis of bright water reservoir sweep improvement and comparison with polymer flooding for improved oil recovery by: akanni olatokunbo olabode thesis submitted in partial fulfillment of the requirements for the. Polymer flooding is one of the chemical methods that recover more oil by decreasing the mobility of the system by increasing the viscosity of the injected water that results in an improvement in the volumetric sweep efficiency. To polymer flooding injection is an important factor and seems to enhance textural/mineralogical changes in heterogeneous systems these results simulate the polymer flooding injection nearest to the production well and indicate that, in this.

After polymer flooding for a long time, (usually two to three years), the oil reservoir will have serious scaling (ie materials sticking to metal surfaces - one of the major problems in the development of oil and gas fields. Iii abstract surfactant-polymer (sp) flooding holds significant promise for enhanced oil recovery, but the procedure for determining the best choice of chemical slug sizes does not consider reservoir mixing. Polymer surfactant compound flooding is a new type of chemical flooding technology which combined two displacing agent-the polymer and active agent together, based on the advantage of a single chemical flooding.
