Isolation Tool Type "D"
The UMS Flowell Isolation Tool Type “D” is designed to seal in both the Top Nipple and the Bypass Nipple seal bores above and below the Y-tool, to allow bull heading of fluids through the Bypass whilst the ESP assembly is fully isolated. By straddling the Y-tool, the Isolation Tool ensures that the ESP leg is remote from all fluids.
The Isolation tool is also used in dual Y-tool ESP applications to isolate the upper ESP when running the lower ESP system. A lock on the Top Nipple prevents the isolation tool from being pumped out of the seated position.
The Isolation Tool is deployed and retrieved using standard Otis GS type running tools.
