KIEV, Dec. 21 - Shell has asked Ukraine to include a potential tight gas deposit in the Donetsk-Dnepr basin on the list of deposits that will be tendered for development under production-sharing agreements.

Shell expects to hear back from the government on January 19, 2011, the head of Shell's representation in Ukraine, Patrick van Daele, told Interfax.

Van Daele did not specify the exact location of the deposit, but said if its reserves are confirmed, Ukraine might double gas production compared with current volumes.
