San Leon Energy, an oil and gas explorer drilling shale rock in Poland, rose the most in five weeks in London trading yesterday after its Rogity-1 well found hydrocarbons.

San Leon climbed 14 per cent to close at 12.5p, valuing the Dublin-based company at £141.8 million (€169.5 million). The well, operated by Talisman Energy, was drilled to a depth of 2,788m, San Leon said yesterday in a statement.

Rogity-1 is San Leon’s second well with Talisman in Poland. The Lewino 1G-2 well encountered gas over more than 1,000m, it said on November 17th. – (Bloomberg)
