Belorusneft – a state-owned Belarus petroleum company – has announced that for the first time it has managed to extract shale oil from a tight rock formation.
The horizontal well in Petrikovsko-Yeletskoy reservoir of Rechitskoye basin has produced oil at the rate of 20 tonnes per day. The oil produced from the horizontal well is viscous, different from the oil traditionally produced by the Rechitskoye deposits. Belarusneft is planning to carry out more drilling to further explore the Petrikovsko-Yeletskoy reservoir.
The Rechitskoye basin has been the location of conventional oil exploration for the last fifty years. After the reserves dwindled the area was considered depleted. However, the top part of the reservoir is characterized by tight rock deposits, containing significant reserves of unconventional oil – out of reach of Belorusneft experts until recently. The newly-deployed horizontal drilling and hydraulic fracturing technology have unlocked the potential of the area which is estimated to hold up to 700 thousand tonnes of oil.
