Russ Oil-Gas

WARSAW, Feb 5, 2009 (Reuters by Patryk Wasilewski) - Gazprom is willing to negotiate an increase in natural gas supplies to Poland to make up for gas that was undelivered because of Russia's row with Ukraine last month, the Polish gas monopoly said on Thursday. "We have received a letter from Gazprom saying there is the possibility of supplementing gas supplies under certain conditions," PGNiG PGNI.WA spokeswoman Joanna Zakrzewska said. Zakrzewska did not say what the conditions were. The state PAP news agency quoted Economy Ministry officials on Thursday as saying Gazprom had asked to sign an annex to Poland's long-term intergovernmental agreement with Russia covering imports of natural gas via the Yamal pipeline. Poland has been receiving only 76 percent of the contracted gas from Russia since Jan 26, when deliveries under a deal with Ukrainian gas intermediary RosUkrEnergo stopped entirely. Poland imports about two-thirds of the roughly 13 billion cubic metres of gas it uses annually. Russia is the dominant supplier.
