  • New offerings fill in the gaps of expandables technology


    David Michael Cohen

    This is the seventh consecutive installation of World Oil’s annual roundup of expandable technology, and the modest number of new products coming to market indicates that this technology has come into its own as a mainstream solution for various drilling, casing and production problems. Nevertheless, operators continue to find demanding applications for established expandable technologies, spurring suppliers to fine-tune designs for these new challenges. In the current installment, we present a liner packer system from Baker Hughes that can be run and installed conventionally, now in production with a new metal-to-metal sealing element; a monobore openhole clad system from Weatherford to isolate openhole problem areas prior to drilling ahead, with a successful rig trial; new, larger-diameter versions of TIW’s expandable liner hanger systems, for deepwater and extended-reach drilling operations; and new applications of Enventure’s high-collapse-pressure solid expandables and expandables with swellable elastomers.
