Gazprom Neft: Record Well at Prirazlomnoye Field Put Into Operation

Gazprom Neft has completed construction of a new production well at the Prirazlomnoye field in the Barents Sea. Directional Drilling Difficulty Index (DDI *) was 7.05 – this indicator is one of the highest in Russia and allows the new object to be classified as super difficult. The length of the well exceeded 6.6 km, which became a new record for the company’s offshore fields.

The construction process was remotely supported online by specialists from the Geonavigator Drilling Support Center located in St. Petersburg. The accuracy of wells placement along the optimal trajectory ensures the use of predictive analytics methods. To further improve the drilling processes, Gazprom Neft is gradually introducing technologies based on the use of neural networks and machine learning systems.

The well stock of Prirazlomnoye already includes 23 objects, the length of which increases with the development of the field and the involvement of more and more distant areas from the production platform into development. By the end of 2021, the project operator, Gazprom Neft Shelf, plans to build another well, which will make it possible to increase production rates. In 2020, Prirazlomnoye produced 3.27 million tons of oil, and in total during the industrial operation of the field, more than 15 million tons were shipped to consumers.

“The new well sets another record for the length at the Prirazlomnoye field. Despite the growing complexity of drilling, we continue to systematically increase the well stock. At the same time, the parameters of the new facility are still far from our technological limit. The experience and competencies of our specialists allow us to build offshore wells up to 9 km long. “
