New Horizons in Wide-Bore Drilling and Completion Technology

摘要

Cantilever drilling technology (CDT) is a new concept ofdrilling which will enable us to drill superwide boreholes withradii of the order of a few feet selectively in zones of ourchoice. We do this using the cantilever drilling tool. Thisenlarged hole will facilitate better artificial lift and enhanceproduction among other things. This paper discusses CDT andRESIN CASING technology which can be used to case holeswith such a unique geometry. Resin Casing is done using anexpandable wire frame balloon structure which forms a mouldfor the specially modified resin forming a hard shell –overcoming the hurdle of casing and cementing the hole.
