Oil States says that the LIWP is designed to safely and cost-effectively plug and abandon aging subsea wells while minimizing wellhead loads and streamlining operations.
Oil States has announced the availability of its new low impact workover package (LIWP). The new technology debuted at the SPE/ICoTA 30th European Well Intervention Conference being held in Aberdeen on Nov. 20-21.
The company says that the LIWP is specifically engineered to enable operators to safely and cost-effectively plug and abandon aging subsea wells while minimizing wellhead loads and streamlining operations.
Oil States says that the fully-integrated LIWP system features a FlexJoint connector as part of the low riser package (LRP), providing a 30-40% reduction in wellhead loading compared to conventional intervention systems that rely on tethering systems.
This design is said to allow for a 15-degree emergency disconnect angle—enabling direct pull and disconnect of the emergency disconnect package (EDP) during drift-off scenarios without complex, expensive connectors.
The LIWP is said to eliminate time- and cost-intensive moonpool assembly and subsea tethering operations, saving 24 hours during installation and 12 hours during retrieval—and as much as $2.5 million per deployment.
