The shift to drilling horizontal laterals, especially in shale oil and gas plays in the US, has led companies often to use coiled tubing units for well completion and intervention work, concludes a ...

A new technique uses concentric coiled tubing with a jet pump to remove drilling-induced damage from horizontal wellbores. The jet pump creates a pressure drop across the formation sandface that ...

Tubing has been a vital component of down-hole activity for several decades, as one of the main means of carrying out intervention operations from reservoir assessment, exploration well drilling and ...

At-a-Glance: Coiled tubing (CT) operations carry distinct well-control, mechanical, and pressure-containment risks driven by thin-wall tubing, continuous bending cycles, and live-well intervention.
