Rosneft as a member of Sakhalin-1 Consortium successfully completed drilling of the world’s longest well from the Orlan platform at Chaivo field in the Sea of Okhotsk.
The length of the well with horizontal completion is 15000 m which currently is a world record. This is a supercomplex well with DDI (Directional drilling index) of 8.0 and 14,129 m stepout.
Sakhalin-1 extended reach drilling is among the fastest in the world owing to the advanced and efficient technologies such as “Fast Drill”. This technology combines high quality modeling of physical parameters of drilling with a structured approach to well designing. Extended reach drilling reduces costs of construction of additional offshore structures, pipelines and other field infrastructure facilities and it also mitigates environmental impact due to smaller drilling and production footprint.
