Rosneft as part of Sakhalin-1 Consortium has successfully completed drilling of the world’s longest well at the Chayvo field

Rosneft as part of Sakhalin-1 Consortium has successfully completed drilling of the world’s longest well at the Chayvo field
With this accomplishment, the Sakhalin-1 consortium currently holds drilling records for nine of the world’s ten longest wells

The O-14 production well was drilled with the Orlan drilling platform in the direction of the field’s south-eastern point.

The well has the world-record measured depth of 13,500 metres and a horizontal reach of 12,033 metres.

“This well continues successful implementation of our outstanding project,” said Igor Sechin, Rosneft head. “I would like to express my thanks to our partners – ExxonMobil. Usage of their drilling technologies made this achievement possible.”

Since the beginning of drilling programme in 2003, Sakhalin-1 has set several world records in extended reach well drilling. With this accomplishment, the Sakhalin-1 consortium currently holds drilling records for nine of the world’s ten longest wells.

In 2013, two consecutive world records for measured depth were set as part of the Sakhalin-1 project. In April of that year, the Z-43 well reached 12,450 metres of measured depth and in June the Z-42 well reached 12,700 metres and a horizontal reach of 11,739 metres

 In April 2014, the drilling team drilled and completed Z-40 well at the offshore field Chayvo of the Sakhalin-1 project. Until the completion of O-14 well this well had a record measured depth of 13,000 metres and horizontal reach of 12,130 metres.

Sakhalin-1 extended reach drilling is among the fastest due to the use of ExxonMobil’s proprietary Fast Drill process. This technology allows bottleneck identification in the drilling process and solution development to enable optimal drilling and completions.

Successful implementation of these state-of-the-art technologies reduces costs associated with additional offshore facilities, pipelines and other production infrastructure. They also protect the environment by minimizing areas involved in drilling and production operations.
