New Horizons in Wide-Bore Drilling and Completion Technology

摘要

Cantilever drilling technology (CDT) is a new concept of drilling which will enable us to drill superwide boreholes with radii of the order of a few feet selectively in zones of our choice. We do this using the cantilever drilling tool. This enlarged hole will facilitate better artificial lift and enhance production among other things. This paper discusses CDT and RESIN CASING technology which can be used to case holes with such a unique geometry. Resin Casing is done using an expandable wire frame balloon structure which forms a mould for the specially modified resin forming a hard shell – overcoming the hurdle of casing and cementing the hole.
