Schlumberger released the ACTive Straddle coiled tubing real-time multiset inflatable packer, which provides all functions needed to isolate and treat multiple zones on a single run without coming out of the well, which reduces intervention time and optimizes production.

The inflatable packer is conveyed with coiled tubing (CT) into vertical, deviated or horizontal wellbores, eliminating expensive mobilizations and potential completion removals by enabling multiple treatments in a single intervention. The CT fiber optic real-time telemetry provides downhole measurements to optimize fluid placement, ensure accurate depth control, monitor packer pressure during setting and unsetting, and enable precise flow control and setting tool manipulations.
During field testing, more than 147 inflation and deflation multisetting procedures were performed. The ACTive Straddle inflatable packer was also field tested in more than six interventions in challenging onshore and offshore intervention conditions, including the Middle East and the North Sea.
In the Middle East, Schlumberger says that a customer needed to identify and remediate multiple plugged inflow control devices (ICDs) in two wells. Using distributed temperature sensing analysis to discover problematic ICDs, a single ACTive Straddle inflatable packer run was performed to restore flow. In one well, production increased by 150% from 480 to 1200 b/d of oil. Production from the second well increased 171%—from 2100 to 5700 b/d of oil, saving more than a week of intervention time compared with conventional intervention treatments.
“Conventional stimulation treatments of multizone reservoirs lack efficiency when targeted coverage is required, leading to lower production recovery,” says Sameh Hanna, Schlumberger president, well intervention. “With the ACTive Straddle inflatable packer, customers now have a robust multiset system that provides precise fluid placement, proper depth control, and ensures packer integrity during treatment using real-time measurements—all in a single intervention.”
