Single-Trip Completion Technology Development for ERD Wells

A well operator wanted to maximize operational efficiency for extended-reach drilling (ERD) wells of more than 45,000 ft measured depth (MD) by converting from a two-trip to a single-trip completion solution. A safety valve, field-adjustable polished bore assembly (PBA), and production packer were developed for the single-trip completion design used in both the producer and injector well environments. Strong collaboration between the well operator and completion technology supplier resulted in a tailored technology development and validation program that reduced operational risk as much as reasonably practical. The technology developer achieved several significant technical milestones during the process, which are discussed in more detail. A pre-run computational modelling strategy was developed to manage deployment risks and ensure the technology operated as designed. The analysis performed using this strategy, along with details on how this data is used to configure the technology is also discussed. Track record details are provided to demonstrate successful deployment of the new technology in a live well environment. To date, the operator has successfully deployed three systems in wells between 30,000 and 45,700 ft MD. The well operator and technology supplier continue to collaborate on ongoing and future wells, where the developed system adds significant value.
