Expro Excellence
CoilHose Well Intervention and Integrity
CoilHose provides Landing String hydrate contingency solution for subsea gas development
Customer challenges
  • A customer was planning a drillship based drilling, completion and well test campaign on a batch of high rate gas subsea wells
  • Following analysis of the well parameters, sea temperatures and hydrate formation curves it was established that there was a significant risk of hydrate formation in the Landing String during the completion and well test phases
  • A contingency plan was thereforerequired should hydrates be encountered in the Landing String during these phases
Expro Excellence
  • An engineered solution was developed for the customer to cater for the different well parameters and hydrate formation scenarios that could be encountered during the campaign
  • The customer had previous experience with using mono ethylene glycol (MEG) for hydrate removal, so a specialized MEG jetting tool was configured for the CoilHose BHA
  • CoilHose was selected over competing coiled tubing and wireline milling methodologies
  • Key factors in the selection of CoilHose were rig-time saving, operational efficiency and a compact rig-up
Value to client
