eRED ball valve helps eliminate approximately 2,400 interventionsDownload PDF
Multiple interventions associated with conventional plug methods
eRED® electronic remote equalizing device
The first eRED® electronic remote equalizing device deployed in 2008 introduced a novel technology that reduced well interventions and simplified operations. Since then, the proven reliable eRED valve has achieved 1,000 installations globally — making it the first electronic remotely operated, multi-cycle valve within Halliburton to reach this record milestone.
During its installation history, the eRED valve has achieved an impressive activation success rate of 98%, measured by requested ball functions vs. actual functions. The eRED valve’s flexibility has allowed deployment in a large variety of applications as a barrier, packer setting and flow control device during completion installment, workover and abandonment operations.
Operators typically performed well plugging operations using conventional plug and prong equipment, which required intervention methods to deploy and set. In complex well applications, additional interventions led to increased costs and risks. Available alternatives, such as single-shot plug devices, provided closed-to-open functionality but applications were limited by the one-time use, particularly if conditions changed during the operation. This often necessitated pulling the plug to surface and running a backup unused valve, significantly increasing time and risks.
Remote open close technology (ROCT) provided a means to reduce intervention operations and costs through the first-of-its-kind eRED valve, which remotely functions using a preprogrammed trigger setup that allows the valve to open and close multiple times, as and when required, without intervention.
Before deployment, the valve can be preinstalled onshore inside the completion tubing and programmed using flexible triggering methods, such as time and pressure, to initiate ball valve movements. For example, upon reaching the desired depth, hydrostatic pressure triggers the eRED valve to “wake up” before closing hours later using a time delay to initiate a barrier within the well. This delay timer allows time to reach setting depth, circulate, and displace fluid before landing the hanger and completing a changeout of the blowout preventer/tree.
remote activation achieved
Since the first eRED valve deployment in 2008, the Halliburton ROCT team has achieved a record milestone, with more than 1,000 installations completed for more than 60 operators globally. To date, the eRED valve has eliminated approximately 2,400 interventions and effectively reduced rig time, costs and the associated operational and health, safety and environment (HSE) risks. The environmental impact gain was calculated as a CO2 equivalent reduction of 67 metric tons† on average during each job.
