Hungarian oil and gas firm MOL Nyrt. (MOL.BU) and its Romanian partner Expert Petroleum SRL won licenses for three exploration blocks in Romania , MOL said in a stock exchange filing Monday.

MOL has a 70% stake, and Expert Petroleum has 30% stake in the blocks. The Ex-1, Ex-5 and Ex-6 blocks are located in western
Romania 's Pannonia basin, and take up altogether 3,434 square kilometers.

The first phase of exploration will likely start in 2011, and according to initial calculations, the blocks have a very good oil and gas potential, MOL said.

There's also unconventional potential in the blocks, MOL added.
