Horizontal wellbores are often favored by operators for exploiting narrow, oil-bearing formations to maximize contact with the pay zone. However, when production causes unwanted gas and/or water to migrate to the wellbore—or uneven production distribution results due to pressure drop in the tubing—operators turn to Halliburton's EquiFlow® autonomous inflow control device (AICD). A simple, reliable and cost-effective solution to the downfalls of passive inflow control, this device works to:
Delay the flow of unwanted fluids such as water and gas into the horizontal wellbore
Increase reliability through design simplicity
Minimize undesired fluid production
Balance production through the interval
Help increase recoverable reserves and extend well production
Reduce cost and risk of handling unwanted fluid at surface
The EquiFlow AICD utilizes innovative dynamic fluid technology to differentiate between fluids flowing through it in order to maximize oil production. The AICD works initially like a passive ICD, yet it restricts the production of water and gas at breakthrough to minimize water and gas cuts dramatically. It has no moving parts, does not require downhole orientation and utilizes dynamic fluid properties to direct fluid flow. Product features include:
Operates autonomously
Contains no moving parts, electronics, or connections to the surface
Requires no intervention
Will cease flow restriction if unwanted fluid recedes
Designs available to produce oil and restrict either water or gas
Utilizes innovative dynamic fluid technology to direct flow
Functions as a standard ICD prior to water/gas breakthrough
Each device functions independently for precise response to the reservoir
