MOSCOW, Oct. 22 (UPI) -- The success of the informal energy summit held by Azerbaijan, Georgia, Lithuania, Poland and Ukraine in Vilnius, Lithuania, last week will be judged later, when the agreements reached there become reality.

But it was certainly an achievement, because it offered more cooperation possibilities for participants, who endorsed the extension of the Ukrainian-Polish Odessa-Brody pipeline to Poland's port Gdansk and refinery in Plock. The pipeline is designed to pump oil from the Caspian to Europe, bypassing Russia.

The sides' oil producing and transporting companies signed a corporate agreement, which became the first practical step to preparing a feasibility study for the pipeline project.

The president of Kazakhstan did not come to Vilnius, but his energy and mineral resources minister, Sauat Mynbayev, said Kazakhstan viewed the project as a practical possibility and could take part in it.

A scheme of interaction between companies involved in the project should be ready for consideration by spring. They can establish a consortium or opt for some other corporate structure. By that time, the sides should calculate framework transit prices, preparing the ground for practical discussions of the amount of oil to be pumped through the pipe.
