Unwanted water production can erode well performance and asset economics if left unmanaged. Interwell’s precision water shutoff approach, grounded in diagnostics and engineered isolation, helps operators identify water-entry points, protect hydrocarbon flow, and restore sustainable well performance in mature and complex wells.

Coiled tubing has a key role to play, with strong arguments for itself: It is used throughout the life of a well, from exploration to abandonment, and its flexibility of use, combined with recent technology developments in pipe materials, real-time downhole telemetry, and specialized downhole tools—just to name a few—opens avenues to perform in a rigless manner many o…
