Russian oil and gas giant Gazprom has successfully drilled the longest horizontal wellbore in the Yamal Peninsula. The well reaches a total 4200 metres in length, with a horizontal borehole of 1500 metres. Final data on well productivity will be established following completion of testing in early 2015.
The Novoportovskoye deposit is characterized by high permeability of rocks, which results in high flow rates of hydrocarbons without the application of fracking.
Gazprom Neft began exploration work on the Novoportovskoye deposit in June 2014. Ultimately, it expects to drill up to 90 wells, 60 of which – within five cluster pads – are expected to be completed within the next three years.
