On 28 December 2017, Belorusneft reported two new oil discoveries in the Pripyat Graben. An exploratory well, drilled at the Makanovichskiy Vostochnyy prospect, tested oil at a rate of 63 b/d from a reservoir in the Semiluki Formation at a depth of 4,200 m. The operator estimated 2P reserves of the discovery at 6.4 MMbbl in-place and 2.8 MMbbl of recoverable. The discovery belongs to the Azeretsko-Khobninskaya structural zone of the central Pripyat Graben. In 2018, Belorusneft plans to record 353 sq km of 3D seismic over the zone. In the Northern Structural Zone of the Pripyat Graben, Belorusneft drilled an exploratory well at the Girovskiy Zapadnyy prospect. The well encountered 6 m of oil pay in the Semiluki Formation. Oil saturation is estimated at 74%. The operator plans to test and complete the well in the first quarter of 2018.
