British oil explorer Cadogan Petroleum suspended drilling at one of its wells in Ukraine and said it would restart operations only by early next year, according to wire reports.
"Due to the onset of winter weather and the complexity of the drilling operations, it has been decided that operations will be suspended temporarily at the current depth of 5,450 metres," the company said, according to Reuters.
Cadogan said results to date from its Pokrovska 1 well were in line with its expectations.
"Management have commenced discussions on using an alternative all-weather rig and hope to recommence drilling operations early in 2011," the company, whose oil and gas activities are located exclusively in Ukraine, said.
The Ukraine-focused company currently has working interests in 11 licence areas covering 14 fields in that country.
