Britain's Aurelian Oil & Gas Plc said on Tuesday it expected resource upgrades across its wider portfolio in the near future.

Aurelian, which has a portfolio of concessions in Poland, Slovakia, Romania and Bulgaria, said the new findings would also include an upgrade in estimates of contingent resources at its flagship Siekierki project in Poland.

The company was responding to a report by the Financial Times on Tuesday that Aurelian could soon announce a large gas find.

Aurelian confirmed that a new competent persons report prepared by Gaffney Cline & Associates was nearing completion. Aurelian shares were flat at 22.5 pence at 1325 GMT on the London Stock Exchange. (Reporting by Kumar Alagappan in Bangalore; Editing by Gopakumar Warrier)
