Cadogan Petroleum PLC, London, plans to test its Blazh-10 well in western Ukraine after open-hole logs indicated oil in the target Paleocene Yamna formation (OGJ Online, Sept. 27, 2018).
The well penetrated a 207-m Yamna section at a depth 50 m higher than prognosis.
Further log interpretation and testing will determine the net pay extent and expected deliverability.
The well reached 3,394 m TD after drilling encountered hole instability described by Cadogan as severe.
It’s on the company’s Monastyretska license near the border with Poland.
