Cadogan Petroleum PLC (LON:CAD) said its Blazh-10 well on the Monastyretska license, in the west of Ukraine, has produced an average rate of 150 barrels of oil per day during the past 24 hours of a clean-up.
The clean-up flow started after the pay zone was washed with acid to remove potential formation damage from mud filtrate.

Cadogan said the produced hydrocarbons will be diverted from the test tank into oil tanks in the area of Blazh-Mon 3 at the end of the clean-up.
The clean-up will continue while the drilling contractor demobilises, after which a full well testing programme will be carried out.
“The results of Blazh-10 are so far encouraging,” said chief executive Guido Michelotti.
“The pay zone is on the high range of values for a success scenario and the well has already produced oil in commercial quantities during the clean-up in natural flow.
“We look forward with optimism to the testing results to have confirmation that the well production capacity is also on the high end of pre-drill expectations.”
