The key to success for a polymer flooding is to use the full potential of mobility control under the premise of good compatibility between polymer and reservoirs.
These polymers have potential for use in mobility control, drilling fluids and profile modification.
The use of foam for mobility control is a promising means to improve sweep efficiency in subsurface applications such as improved/enhanced oil recovery and aquifer remediation.
Laboratory miscible CO2 and CO2-foam injection tests were performed to study CO2 EOR in fractured carbonate core plugs and to evaluate the feasibility of using foam for mobility control in fractured systems.
Use mobility control to guide the router from the initial position to the optimal position, such that end-to-end throughput of the route is improved.
Using PSO, we find an optimal position for the receiving router of minimum throughput link and then move the router to that position using the mobility control (MC).
The route is reconfigured by moving the router to the optimal position using feedback mobility control.
Since ASG processes combine both the concepts of IFT lowering and using foam as mobility control agents, they are mostly encouraged for HTHS carbonate reservoirs, where the functioning of polymers usually deteriorates (Lake 1989; Niu et al. 2001).
Blaker (1999) investigated the use of foam for gas mobility control in the Snorre Field, one of the major oil fields in the North Sea, located 150 km offshore.
