World's longest well drilled in Sakhalin



A record-breaking well has been drilled from the Orlan platform at the Chaivo field in the Sea of Okhotsk.
The well in question reaches 15,000m and is classed as a supercomplex well with a DDI (Directional Drilling Index) of 8.0 and 14,129-m stepout.

Rosneft, a member of the Sakhalin-1 Consortium, is responsible for the feat, with the length of the well with horizontal completion being 15,000m making it a world-record achievement. This is a supercomplex well with a DDI (Directional Drilling Index) of 8.0 and 14,129-m stepout.

This is not the first record to have been broken at Sakhalin. A number of world-records have been set with the Sakhalin-1 Consortium having drilled nine out of 10 of the world’s longest wells.

Sakhalin-1 extended reach drilling is reportedly amongst the fastest in the world owing to advanced technologies such as ‘Fast Drill’. This technology combines high quality modelling of physical parameters of the drilling, coupled with a structured approach to well designing. Extended reach drilling reduces the costs of construction of additional offshore structures, pipelines and other field infrastructure facilities and also reduces the environmental impact of activities thanks to its smaller drilling and production footprint.
