High flowrate obtained at Gazprom Neft's Vostochno-Messoyakhskoye field
MOSCOW -- Messoyakhaneftegaz, the Rosneft—Gazprom Neft joint venture, has completed construction of its first deep-strata horizontal production well at Vostochno-Messoyakhskoye field, with initial inflow of 250 tonnes of oil per day, confirming the high potential of developing the deep strata of Messoyakha fields.
The deposits are Early Cretaceous, formed 136 million years ago, and contain lighter crude than the main reservoir under development, located 800 m underground. The depth of the new well, with two pilot boreholes, runs to 3.3 km, with a total length of 4.4 km.
Following hydrodynamic and geophysical investigations (well logging), multi-stage hydraulic fracing of the strata will be undertaken — the first time such an operation will have been undertaken in a well of this kind at Messoyakha. The information obtained will allow a decision to be taken on the further drilling of onshore deposits in the Arctic Mainland. A further 10 deep wells are expected to be commissioned by Messoyakhaneftegaz in 2018.
