Z-line® composite fiber optic sensing campaigns provide well diagnostics for Statoil

Ziebel successfully completed a distributed fiber optic (DFO) sensing campaign for Statoil. Ziebel used the Z-Line®, its new gravity-deployed carbon composite cable, to gather Distributed Temperature and Distributed Acoustic fiber optic data on the Huldra installation, Statoil’s first unmanned platform, which ceased production in September 2014. The interventions were carried out to optimize Statoil’s plans to plug and abandon the installation next year.

Working from the Huldra platform, Ziebel ran the Z-Line® in two wellbores to measure temperature and acoustic profiles. Work was carried out by Ziebel over two 3-day periods in April and May 2015. Each operation was completed as planned, providing data that displays the conditions of each well in its entirety, during each intervention. It allows Statoil to observe fluid movements, confirm the integrity of the wells, and plan the final abandonment, enabling the optimization of the forthcoming plug and abandonment campaign.
