The W-AFV can be redressed and reinstalled
The Zenith Wireline-Retrievable AFV is typically installed on a standard lock in a ported nipple or sliding sleeve situated above an ESP and can be retrieved from the well with slickline and replaced with an isolation sleeve. Running or pulling the valve with standard wireline tools addresses any concerns relating to additional equipment in the well bore.
Facilitates increased production
- Significant production increase unlocked by allowing continued flow to surface by bypassing the restriction of the ESP when pump is switched off
- Interventionless operation as no control lines or wireline intervention required during normal operation
- Value enhanced through opportunity to reinstall in subsequent wells
Increases ESP runlife
- Prevention of damage to the stationary pump by reducing scale, wear and debris build-up by channelling flow through the annular ports
- Further damage avoidance on shut-down by avoiding tubing solids descending into the pump
- Prevents ESP back-spin or breaking motor shafts at start up
A derivative of the W-AFV can be included in the Zenith Total Protection Bypass system.
