Drilling and Cementing Technology

Continued Evolution of the One-Trip-Expansion, Single-Diameter Wellbore

With more than 300 commercial installations in place, solid-expandable-tubular technology has proved to be a viable and economically feasible alternative to conventional drilling technology. The need for lower lifting costs and to maximize recovery has provided the impetus for the latest step change toward the one-trip section, single-diameter wellbore. In addition to the unique equipment needed to expedite this game-changing technology, new implementations essential to realize the tool components and contingencies had to be developed and tested. The full-length paper explains the overall design and testing approach necessary for the construction of a single-diameter well.
