Based on the stratigraphic column andoffset data a preliminary well design

is produced.

Peer review conducted to analyse and refine the design.

Well hazard assessment conducted with the aim of identifying all

potential hazards and establishing control/mitigating measures.

Well design finalised and Drilling Programs produced.

Performance monitoring KPI’s established.

TUBINGHANGER• Wells will be drilled in accordance with the

Drilling Programs. Modifications to well designs and procedures can only be made with the approval of the Drilling Manager.

• Drilling performance will be closely monitored at the rigsite and in Tehran.

• Regular discussions between the rig and Tehran will aim at optimising operations and maintaining a high safety standard.

• Data will be transmitted from the rigsite to Tehran on electronic format. Other packages will be used to monitor performance and assist in planning future wells.

• Upon completion of the drilling phase the well will be tested and completed as per the Completion Program.
