FluxRite
FluxRite combines MeshRite with inflow control devices (ICDs) for horizontal production/injection wells to: 1) minimize water/gas coning, 2) evenly sweep the reservoir from toe to heel to maximize oil recovery, and 3) minimize water influx from high-perm streaks such as fractures. FluxRite screens can be combined with "swell packers" to minimize annular flow and isolate unwanted shale zones or high-perm water streaks. For most applications tungsten carbide flow nozzles (ID = 1.6, 2.5 or 4.0 mm) are used as ICDs because of high erosion resistance and the pressure drop across a nozzle is independent of fluid viscosity. However, for low-viscosity, ultra-high-flow applications, nozzles are combined with channels to maximize the productivity and life of the completion. NEToolTM-a powerful wellbore-reservoir simulator that can import EclipseTM output files-is used to design the ICD strength and isolation packer location(s) along the wellbore. FluxRite is designed to allow the ICD strength to be adjusted at the wellsite in the event that new information materializes during drilling and logging. Although MeshRite is the preferred sand control screen for FluxRite, it can be made with other screen media (wire-wrap or premium) or without sand control. Flow control for horizontal wells is rapidly gaining popularity because the significant return on investment.
