The VES solutions for reservoir fluid flow control should be resilient to these factors because reservoirs have temperatures of around 60 °C and injection fluids have salt concentrations of 3 20 wt% (covering the range from sea water to the saturated brines found in aquifers).
Compared to the F value for the one fracture reservoir, applying flow control for the range of (sigma _h/leftlangle w rightrangle) investigated was capable of increasing F to a range of 0.50 0.31, which represents 100 89%% of the value of the one fracture reservoir.
Real-time adjustments of the water injection rates based on closed-loop surveillance of the pressures in producer wells can redirect and control the reservoir flow such that the floodfront arrives simultaneously at all producers.
In the flow control mode the controller automatically raises the bottom hole pressure setpoint, and thereby keeps the reservoir fluid flow to the surface within a tunable threshold.
The placement design of inflow control valves in petroleum wells is based on the viability of their installation to improve the flow control from the reservoir to the well.
Flow control would be limited if the reservoir consists of fracture-to-fracture intersections as ICD can only control flow in the fractures that are directly connected to the wellbore.
The controller implements an automatic switching from constant bottom hole pressure (CBHP) regulation to flow control mode in the event of a reservoir kick.
However, flow control was able to overcome nearly all of the additional loss of thermal performance for the multifracture reservoir.
The primary reservoir characteristics that must be considered include: types of fluids in the reservoir, flow regimes, reservoir geometry, and number of flowing fluids in the reservoir.
