The well of the Sakhalin-1 project has the world's largest depth along the trunk - 13 500 meters
Rosneft, a consortium of the Sakhalin-1 project, completed drilling the world's longest well at the Chayvo field. The well has the world's largest borehole depth - 13 meters, the press service of Rosneft reports.
“This well is a continuation of the successful implementation of our outstanding project. I express my gratitude to our partners - ExxonMobil, thanks to the use of drilling technologies, which made this achievement possible ", - said the head of Rosneft Igor Sechin.
We are talking about several of our own drilling technologies of ExxonMobil, including Fast Drill technology, which allows to provide the most optimal drilling results. Successful application of such technologies allows to reduce costs for the construction of additional infrastructure facilities and also helps to protect the environment by reducing the area of drilling and mining operations.
To date, the Sakhalin-1 Consortium has drilled 9 of the 10 longest wells in the world. As for the Sakhalin-1 project, in 2013, the project set two records at once for drilling wells with the world's largest wellbore depth (well Z-43, 12 meters deep and Z-450, 42 meters deep). In April 12, well Z-700 was drilled in the Chayvo offshore field of the Sakhalin-2014 project, which until recently had the world's largest borehole depth of 1 meters.
