Case Study Expandables Optimize Deepwater Well Design Challenge This was the first post-Macondo GOM deepwater exploration well to receive a permit to continue drilling using subsea BOP’s. The Operator needed to achieve zonal isolation across shallow hydrocarbon-bearing sands below the 16 in. casing shoe while providing an additional and proven mechanical barrier above these sands. To improve quality of the cement job of the well’s 9-7/8 in. production liner, ECDs during the cementing operations needed to be reduced. Added Value The SET ® system provided zonal isolation and a second barrier above the shallow hydrocarbon-bearing sands and allowed conditions for running the 13-3/8 x 13-5/8 in. casing string. The production casing being run as a liner with a tie
