Multiple sleeves to be opened
An operator in the Middle East needed to open the sliding sleeves in
multiple ICDs in a new horizontal multizone ResFlow completion. Designed to
allow selective shutoff of reservoir zones, the completion had been installed
with all of the sleeves closed, and now they required opening to begin
production.
Measured confirmation of shifting
ReSOLVE instrumented wireline intervention service, configured as the
universal shifting tool, makes multiple shifts in any direction in a single
run, which is ideally suited for multiple components in multizone completions.
The UST is run with ReSOLVE service's anchor and linear actuator, and
throughout the operation, the ReSOLVE service measures force and displacement
in real time to confirm that the expected force and distance were achieved and
verify shifting.
To open or close a well component, the UST radially extends profile keys
to engage the component. The keys are extended with a specified preload force
but remain compliant to navigate well geometry. The preload force is precisely
controlled for the well conditions and conveyance method. Once the UST is
latched into the profile of the component, the anchor secures the tool in the
well, and the linear actuator extends or retracts to shift the component. The
keys are fully retractable into the UST to enable the tool to pass by ledges
and other restrictions in the well.
