Exillon Energy has discovered oil at the EWS I - 44 well on the south-eastern part of the East EWS I field in Siberia.

The well flowed water-free oil naturally to the surface with a flow rate of 768 bbl/day on a 10mm choke.

The company drilled the well directionally 1.3km to the west from the existing well pad.

EWS I – 44 encountered the Jurassic P reservoir at 1,834m, confirming 7.3m of effective net oil pay within the Jurassic and 3.1m of oil-water transition zone.

On completion of testing, the well will be connected up to existing production facilities, the company said.
