Results Move Cadogan to Change Testing and Drilling in Ukraine

Cadogan Petroleum Plc has announced lower than expected results from two of its Ukrainian drilling and well testing programmes. The company says that testing on the Pokrovska and Zagoryanska gas fields in eastern Ukraine has necessitated deepening of the Pokrovska-1 well and the repositioning of the Zagoryanska-1 well.

"The Pokrovska 1 well was deepened to 5,762.5 meters into the Lower Visean V26 interval where logging of the V26 indicated it to be water bearing," a statement read. "As a result the zone was plugged off to enable testing of the overlying V24/V25 interval, which log data indicates is gas bearing. The equipment required to undertake a full well test on Pokrovska 1 will be moved into location during October in order to comprehensively evaluate the V24/V25 interval. The Saipem drilling rig has been moved on to the Pokrovska 2a location, where drilling is planned to commence this month."

It continued: "On the Zagoryanska licence, a work over rig has completed the intervention program at the Zagoryanska 1 well and is now being moved to the Zagoryanska 2 well location to carry out further work over operations. At Zagoryanska 1, testing of the secondary target V23/V24 proved to be non-productive. The well was recompleted in the primary V18/V19 target and perforated.  A coiled tubing unit is being mobilised to Zagoryanska 1 to continue the testing program on the V18/V19 interval. This interval is currently producing at the Zagoryanska 3 well, located about 800 meters from Zagoryanska 1."

The company also announced a new well, called Zagoryanska-9, which will be located at the upper and lower Visean section.
