An international oil and gas exploration company, Kulczyk Oil Ventures has announced that the North Eastern Ukraine- based O-14 exploratory well located in Olgovskoye Field has been cased after having encountered 8 potential gas bearing reservoirs.
While the O-14 well was being drilled to a total depth of 2,800 m, the gas-bearing zones were found in the well’s Lower and Middle Bashkirian regions. To achieve greater gas production capability, the well at Olgovskoye Field was drilled further into an isolated fault block where there was no previous record of gas production. The production testing of the exploratory O-14 well is likely to commence within the next two months.
Since Kulczyk Oil Ventures acquired a 70% stake in KUB-Gas last year, O-14 is the 3rd well drilled by the company on the Olgovskoye license. Currently, four wells in the Olgovskoye Field, viz., O-7, O-5, O-4 and O-3 wells produce gas.
In January this year, Kulczyk Oil completed drilling of the O-8 well. It was drilled to a total depth of 2,780 m and potential hydrocarbon-bearing zones were also identified. In April, O-9 well was drilled and cased to a total depth of 2,638 m and was identified as a multi-zone gas well. Testing and Completion of the O-9 well signify a new zone of gas discovery known as the R37 unit.
Kulczyk will now move the drilling rig to another location at O-12, situated at the field’s northern end. It is designed to test the gas-bearing reservoirs located in the Middle Bashkirian and Muscovian regions. The drilling for the O-12 well is likely to commence later this month.
