JKX Ties Back Rudenkovskoye Well

JKX Oil & Gas plc has completed and tested the deeper of two hydrocarbon-bearing intervals in Well R102 as part of its ongoing drilling program at Poltava, Ukraine. Well R102 is the second new well to be drilled by JKX on the Rudenkovskoye Field.

During testing, Well R102 flowed at an average rate of 7.7 million cubic feet of gas, 90 barrels of condensate and 230 barrels of water per day, with a wellhead flowing pressure of 1,210 psi through a 50 /64-inch choke. The well has been tied back to the company's production facility via a new 4.5-km flowline.

Well R102 is a vertical well in the southern area of Rudenkovskoye Field. It targeted the Devonian sandstone reservoir approximately 2.2 km from Well R12 which was re-entered and sidetracked by JKX in 2005 and continues to produce gas from the Devonian sandstone. An extensive data acquisition program was carried out on Well R102 including 77m of cores and image logs. Using this data, the lower 45m interval from 3,630m to 3,675m depth was selected for open-hole testing to maximize connectivity with the natural fractures identified from the image logs.

A second 138m interval from 3,212m to 3,350m depth has been identified as a suitable target for fracture stimulation. The timing for testing this interval will depend both on the performance of the current producing interval and the results of the fracture stimulation program on Well R101 that is scheduled for next month.

Since drilling Well R102, the Skytop N75 rig has drilled and completed Well M160, which targeted a potential northerly extension of the Molchanovskoye Field. Testing of Well M160 is scheduled for the coming week. The N75 rig has now moved to the Ignatovskoye Field where it has spudded Well I127 which will target the oil leg in the Visean Carbonate.

JKX Oil & Gas plc is an exploration and production company listed on the London Stock Exchange. The company has license interests in Ukraine, Georgia, Russia, Italy, Bulgaria, Turkey and the United States.
