LONDON – bp has deployed technology from LYTT to help raise production from the Clair Ridge complex west of Shetland.
LYTT specializes in developing real-time insights by combining fiber optic data with hybrid analytics. Using these insights, bp modified water and oil production at Clair Ridge to achieve up to 2,000 b/d improvements.
Clair Ridge, the second-phase development of the Clair field, came onstream in 2018. There are various reservoir issues related to well integrity, water inflow, and the complex, fractured subsurface.
Prad Thiruvenkatanathan, co-founder and chief product & technology officer at LYTT, said: “To support bp’s engineers in driving production, managing integrity and increasing field recovery, we delivered in-depth real-time flow surveillance data by deploying existing fiber optic cables as downhole sensors.
“LYTT then applied hybrid analytics to generate critical insights into in-well flow dynamics from Distributed Fiber Optic Sensing data in real-time.
“Our technology gave bp’s engineering team the capability to understand exactly how much water was being produced by the asset, which zones of the well were producing this water and, crucially, when it was being produced.”
This understanding of flow dynamics, he added, helped the engineers to ‘tune’ the choke setting of the well to remediate water production while optimizing oil production, in addition to placement of a water shut-off intervention.
Teymur Sadigov, Senior Petroleum Engineer, bp, added: “LYTT’s insights and data enabled us to identify new opportunities which we look forward to applying across our fiber-enabled well stock.”
