Oil and gas explorer Petroceltic has signed a deal to transfer operatorship of the Carisio exploration permit in the western Po Valley in Italy to Eni.

Petroceltic holds a 47.5% interest in the Carisio exploration permit.

The company will transfer the operatorship in exchange for 550 kms of existing 2D seismic data on the Ronsecco permit and access to reprocessed 2D seismic data and other technical studies in the Carisio permit.

Petroceltic said that this acquired data will provide the basis for the planning of the material Rovasenda-1 well and the possible farm-out of part of the company’s interest in the Carisio permit.

The company is now planning to drill the 270 million barrels Rovasenda exploration prospect in the first half of 2012.

The Carisio and Ronsecco permits are located in Piedmont region, about 30 kms west of the Eni-operated Villafortuna-Trecate oil field.
