One Step Ahead When planning an intervention job on a subsea well, do you really know the condition of your main well barrier, the wellhead? Thanks to enhanced drilling and intervention technology old wells are still producing. Deepwater rigs and post accident requirements increase the size and weight of subsea drilling equipment. Documentation of old wells is often lacking or hard to find. WellCare™ is a service to help oil companies document the integrity of well barriers.

WellTrack™ Software SolutionWellTrack™ is our key tool for providing the WellCare™ service. WellCare™ delivers information on wellhead integrity, equipment, and history. 4Subsea provides customers access to WellTrack™ with a “Software-as-a-Service” solution (SaaS). The software gives access to information about wellhead systems including:• Integrity status of each well• Operational history of each well• Design documentation, drawings, and analysis reports• Track component properties across fields and wells• Rig data linked to the operational history of wells• Measurement data on wellhead from rig operations• Soil data

Proven Technology4Subsea currently provides lifecycle management services to about 200 subsea wells. Through our work we have built considerable experience in efficient data collection and structuring. Once data have been gathered and the integrity status is established, maintenance of the integrity status per well is very cost efficient.

Well Integrity Monitoring Deliverables• Monitoring of loads on wellhead during operation• Evaluation of integrity during operations• Fatigue monitoring• Fatigue and wellhead loading forecasts
