This presentation will present an overview of the multiphase pump system on Chevron’s Jack & St. Malo (JSM) project, how its configuration evolved over time, and the opportunities and obstacles that were encountered during execution. Subsea boosting has always been a key method for enhancing recovery on JSM starting with subsea single-phase pumps being installed as part of JSM Stage 1 in 2014, and with plans to subsequently install subsea multiphase pumps in a future stage. In 2021, the first multiphase pump was installed at Jack as part of JSM Stage 4 and a second pump was installed at St. Malo in 2022. But the path for implementing the multiphase pumps was very different from what was originally envisioned when the JSM project started. As a result of enhancements, the multiphase pump system currently in operation at JSM is less complex, has additional functionality, and was executed at a significantly lower cost than the system originally planned by the project.
