An innovative application of expandable liner technology re-lined a non-sour-gas-compliant wellbore, effectively clearing the way for a gas-lift re-completion and restoring production to a pressure-depleted Eagle Ford oil well. The non-traditional installation, executed by Weatherford and ConocoPhillips, established a world record for a solid-expandable liner run. The expandable liner was run trouble-free to 7,047 ft, effectively isolating the existing casing and casing hanger from H2S. The well was then completed with 23/8-in. tubing, a retrievable production packer and a traditional side-pocket-mandrel gas lift. The well has since been on continuous gas-lift production with up to triple the pre-reclamation rates, and with zero HSE issues related to wellbore integrity.
