KIEV, March 23 - Ukraine plans to hold tenders for production sharing agreements (PSA) for three hydrocarbon sections - Skifske and Foroske (both in the deep-water shelf of the Black Sea) and Slobozhanske (shale and central basin gas field in Kharkiv region) - in 2012.

The State Geology and Subsoil Service said that investments in implementing all three of the projects are estimated at about $50 billion, while cumulative gas production could total up to 11-15 billion cubic meters (bcm) per year.
