Expro Excellence
Well Testing
Delivery of efficient flowline processing for a decommissioning project
Objectives
  • Expro was approached by Boskalis on behalf of Spirit Energy to provide a solution to safely decommission a flowline which was tied back to a subsea well on the Morecambe platform in the Irish Sea.  The well had come to the end of its economic life - cleaning and disconnecting the flowline was the first step in the decommissioning process
  • Mobilisation was required within two months of the initial project award
  • The scope of work leveraged Expro's hydrocarbon and fluid handling capabilities on the platform.  These included:
  • Process control and degassing
  • Fluid handling and water filtration
  • Onsite water analysis using Fourier-transform infrared (FTIR) technology
Expro Excellence
  • Expro was part of an integrated team incorporating personnel from Platform Operations and the Dive Support Vessel 
  • The work scope was to flush and clean 8.3km of 8" subsea flowline and control umbilical
  • This project is an example of how Expro's capabilities can be readily applied to non-standard hydrocarbon containment operations such as pipeline decommissioning. It clearly demonstrates the adaptability of Expro Well Test personnel and equipment
  • Expro worked closely with Spirit Energy and Boskalis to establish detailed plans which resulted in a non-standard hydrocarbon containment operations such as pipleline decommissioning, it clearly deomnstrates the adaptability of Expro Well Test personnel and equipment
  • Expro worked closely with Spirit Energy and Boskalis to establish detailed plans which resulted in a non-standard operation being performed efficiently and without incident.  The planning and operational highlights included:
  • An extensive site survey that ensured a practical, solution-based approach
  • Development of a comprehensive method statement to deliver the operation, on a job-specific level (including contingencies)
  • Utilisation of Expro's Fluid Sampling service, with a production chemist on board the platform to ensure that cleanliness objectiveness were met before disposal overboard
  • Efficient handling of the crosslinked gel containing solvent and surfactant from the pipeline, enabling the fluids to be separated and sent to the platform facilities without any interruption to production
  • The integrated team used their exceptional experience and communication skills to ensure the successful completion of the project, overcoming the challenges of high flow rates, (6.25 bbl per minute), a difficult working environment and the installation of temporary equipment on a fixed installation
Value to client
  • Intensive planning resulted in continuous operations with zero NPT avoiding the additional cost of Dive Support Vessel delays
  • The flushing operation ( 8 hours pumping) was completed ahead of schedule exceeding the expectations of the client representative who awarded the crew a customer performance of 100%
  • Expro were commended for their safe, efficient rig up and execution of the work during the project
