MOSCOW, May 7 - Gazprom is thinking of entering the Ukrainian compressed natural gas (CNG) engine fuel market, one of the FSU's biggest.

Gazprom Sales Ukraine has sent out requests for quotations for contracts worth up to $220,000 each, to perform a financial feasibility study to buy compressed natural gas filling stations in Ukraine, and to draft a business plan to build and expand infrastructure to sell compressed gas.
