DRILLING EQUIPMENT SET INSTALLED (STAD)

SIMOPS DRILLING & COILED TUBING DES

This DES has been developed simultaneously with the STAD (Semisubmersible Tender Assisted Drilling) for the Moho-Nord Project, including the drilling of 24 wells to 8500m extended reach, in 800 m of water from a TLP (Tensioned Leg Platform).

Drilling and coiled tubing operations can be performed simultaneously. Overhead clearance above BOP floor allows transfer of coiled tubing injector head.
