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
