Client Challenge
Petronas, one of the largest integrated oil and gas corporations, required rig positioning and well setting QC services, for a deepwater exploration project off the coast of Mexico. This marked a new high profile entry into the region for Petronas.
How we helped
We applied our extensive experience in surveying and rig positioning to install an upgraded LR V-NODE unit, containing DGPS (Differential Global Positioning System), heading and AIS (Automated Information System) sensors on the rig, which allowed the rig’s position to be accurately identified, with data sent in real time to our innovative IRIS web mapping site. The position of the rig and drill centre was then independently computed and displayed live on the web map, enabling additional onshore quality control.
The following technical assessments were carried out:
- Risk assessment review
- Rig positioning scope determination
- Task plan finalisation
- VNODE installation
- Positioning quality control checks
- SBL calibration QC
Our rigorous QC process set the seabed well position perfectly first time without the need for any corrective vessel moves, therefore validating the integrity of the well position and generating efficiency within the critical pathway.
Powerful results
One exploration well was set during the project and was spudded efficiently and successfully without any issues or down time associated with the positioning operation.
Vysus Group’s experience in surveying and rig positioning helped to successfully position a deepwater well and minimise any potential risks and downtime.
