Rosneft as part of the Sakhalin-1 Project Consortium successfully completed

drilling at the Chayvo field, the longest well in the world.

Production well O-14 was drilled towards the extreme southeastern end of the field from the drilling rig O-14.

end of the field from the Orlan drilling platform. The well has the

well has the world's deepest wellbore depth of 13,500 meters and a horizontal section of 12,033 meters long

wellbore length of 12,033 meters. It took 156 days to drill the well.

Our employees assembled scaffolding in particularly extreme conditions, which is what the Orlan project is known for.

The employees were tasked with erecting a large suspended structure over the sea in a confined space inside the platform well. Our heroically brave employees were accompanied by observers and 2 rescuers during the work.

The scaffolding was erected for the subsequent stripping of the well by other workers.

After clearing the well, our employees started dismantling the structure.
