Increase hydrocarbon reserves and rate of recovery
Talk to an expertHorizontal wellbores provide access to narrow, oil-bearing formations for maximum contact with pay zones. However, when production causes unwanted water and/or gas migration to the wellbore, or creates uneven production distribution, operators turn to Halliburton EquiFlow autonomous inflow control devices (AICDs). The EquiFlow AICD helps delay and reduce the flow of unwanted fluids and stimulates balanced production throughout the entire interval.
EquiFlow AICDs are Type 2 inflow control devices (ICDs) that use innovative dynamic fluidic diode technology to distinguish the types of fluids flowing through the device and optimize oil production and recovery. The EquiFlow AICD performs similarly to a standard ICD during oil production, balancing inflow, yet restricts water and gas production at breakthrough, dramatically minimizing water and gas cuts. EquiFlow AICDs use no moving parts and require no downhole orientation. Additionally, the devices provide injection capability and use the dynamic fluid properties to direct flow. All these features enhance long-term functionality and reliability.
Balances production flow and restricts unwanted production fluid, even with minimal viscosity difference between the produced fluids.
Combines the benefits of inflow balancing with the flexibility to reconfigure the ICD as needed.
Typical applications include wells experiencing heel-toe effects, water/gas breakthrough, permeability differences, and water or gas challenges in horizontal or layered reservoirs. The EquiFlow AICDs have been installed in stand-alone screen (SAS) completions, openhole gravel packing (OHGP), through tubing/inner string, multilateral wells, and sandstone/carbonate formations. The EquiFlow AICD comes in four different designs that address viscosity oil ranges from very light to very heavy oil
