ReSOLVE Service's Universal Shifting Tool Opens 10 Sliding Sleeves in Two Runs

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.
