WORLD-RECORD CORE RUN DELIVERED BY QATARGAS ON NF-26 APPRAISAL WELL

Drilling rig, Les Hat, is currently on NF-26 as part of the North Field Appraisal Project. It recently cut and recovered its first Khuff run safely and efficiently, while at the same time, it also achieved the longest coring run performed by any operator in the world.

The total recovery on this run was 733.98 feet (223.78 metres) of core.

The previous world record run was 708 feet (215.79 metres) in Canada in 2018, while the previous North Field record was 690 feet (210.31 metres), also by Les Hat that same year.

This remarkable achievement is testament to the continuous collaboration and communication between all stakeholders throughout the planning and execution phases.

Qatargas management congratulated the Les Hat rig team, Drilling and Completions Department (Qatargas), Petroleum Engineering Department (Qatargas), QatarEnergy, and the Baker Hughes coring team on this outstanding world-record core run.

• The implementation of lessons learned from North Field appraisal wells drilled to date

• The utilisation of a stabilised Baker Hughes JamBuster conventional coring system

• Emphasis on connection practices and drilling parameters to maintain bit engagement

• Advanced 24/7 monitoring and parameter adjustments by field supervisors and office support

• Performed preventative maintenance on rig equipment including the top drive system (TDS) to avoid interruptions

• Diligent QA/QC pre-job checks on coring equipment to ensure reliability.
