Case Study

World First N2 unloading of well using CoilHose™ on Riserless Well Intervention vessel

In Brief

World's first well to be successfully unloaded with CoilHose™ using RLWI

Customer Challenges

  • Equinor had a newly completed well that had been left with a full column of brine during the completion phase.  Simulations showed that N2 gas lift was necessary to start production
  • The alternative to CoilHose™ would have been Coil Tubing which is logistically challenging, High POB and very much weather dependent
  • Equinor had previously worked with Expro and have a good understanding of our CoilHose™ technology and our ability to perform open water intervention from RLWI with a limited footprint and less POB

Expro Excellence

  • World’s first well to be successfully unloaded with CoilHose™ using RLWI
  • CoilHose™ was positioned at a depth of 2,150 mMD while the well was unloaded over a period of 7hrs
  • Expro deployed a ‘hybrid’ CoilHose™ package to work in conjunction with the customers preferred wireline vendor resulting in a fully integrated service delivery platform
  • The project was completed safely and ahead of planned timings

Value to Client

  • The project duration was significantly improved by utilizing the CoilHose™ solution compared to traditional Coil Tubing
  • A reduction in carbon footprint through delivery of an integrated solution
