A joint venture of Rosneft and Gazprom Neft has confirmed the potential of deep strata in Vostochno-Messoyakhskoye oil field in northern Yamalo-Netets Autonomous Okrug of Russia, 340 km north of Novy Urengoy (OGJ Online, Sept. 22, 2016).
The venture, Messoyakhaneftegaz, achieved initial flow of 250 tonnes/day of oil in its first deep horizontal well.
The well, with two pilot boreholes, went to 4.4 km TD in Early Cretaceous pay at a depth of 3.3 km. It was completed with multiple-stage hydraulically fracturing.
The oil is lighter than that produced in the main reservoir, the depth of which is about 800 m.
Messoyakhaneftegaz expects to drill 10 more deep wells in the area in 2018.
