The record was set at the Bolshetirsky oil field. The work was carried out on a modern Bentec HR 5000 drilling rig. Previously, the maximum horizontal drilling length was reached at the Markovsky oil and gas condensate field and amounted to 1,757 meters.

“At the design stage, we had to take into account all the nuances: the selection of downhole and surface equipment, geological uncertainties, drilling parameters. During preparation, we took into account our past experience and thoroughly analysed the drilling of previous wells,” noted Konstantin Petrukhin, a Director of Drilling of Irkutsk Oil Company.

The equipment was designed by order of Irkutsk Oil Company to work in the conditions of East Siberia. The contract for the delivery of 7 new Russian-made drilling rigs was signed in 2019, and the first three rigs were launched at the fields in 2021. Four more rigs are scheduled for delivery in the first half of 2022. The equipment was purchased with a subsidized loan from the Industry Development Fund.

Bentec is one of the world's leading manufacturers of drilling rigs and oilfield equipment with more than 125 years of history. The company manufactures high-quality drilling rigs and equipment for the oil, gas and geothermal markets, with a focus on health, safety and environmental protection.
