FX Energy, an independent oil and gas exploration and production company, has begun drilling of the Lisewo well on its 850,000 acre Fences concession in western Poland.

The well is planned to test a 3-D defined Rotliegend sandstone structural target and the expected total depth of this well is 3,945m.

FX Energy CEO David Pierce said that the Lisewo prospect has the best risk-to-reward ratio of any well in the history of the company.

"Because of the potential size of the prospect, a success at Lisewo could lead to one or more additional drilling locations in this same area," Pierce said.

FX Energy owns 49% of the Lisewo well, while Polish Oil and Gas Company holds the remaining interest and is the operator.
