Save time, improve efficiency and data quality, and eliminate battery risks in CT interventions

Award-winning ACTive Power CT real-time powered downhole measurements system delivers continuous fiber-optic data and power from surface through a hybrid cable in the tubing, eliminating the need for batteries to power downhole tools. The result is virtually unlimited downhole intervention operation time for powered tools—including logging tools—with real-time downhole data through fiber optics.

With fewer trips to surface to replace batteries, operations are more efficient. In addition, downhole tools that were previously used in some longer operations only intermittently during the job to avoid premature battery depletion can be used continuously to improve data quality and interpretation capabilities, leading to enhanced decision-taking and overall operational performance. New tools and operations can also be developed that previously were impossible because of battery limitations.

The 2020 World Oil Awards advisory board selected ACTive Power system as the winner of the Best Well Intervention Technology Award.

Because ACTive Power system eliminates the battery module, it simplifies rigup for operations such as selective stimulation and perforating, which often have long BHAs.
Enables virtually unlimited downhole intervention operation time and uninterrupted data flow
Extends operational temperature window
Eliminates lithium battery disposal and risks
