A sidetrack on the Uzenskoye #9 well on the flank of the Uzenskoye oil field, was drilled and successfully intersected a section of the main Aptian reservoir updip from the original bottom hole location. However, when put on production, the well flowed water, indicating that the oil:water contact in the field has migrated to a higher elevation than had been anticipated on the basis of cumulative production of oil from the field. This higher than anticipated oil:water contact is likely to have implications for the remaining recoverable reserves on the Uzenskoye field which will need to be reassessed with the new data derived from this well.

Meanwhile, production remains steady from the existing producing wells in the field, from which production is currently running at approximately 1,050 barrels of oil per day, in line with expectations
