Gazprom Said to Seek EON, BASF Payment for Siberian Gas Reserves

OAO Gazprom, the world’s biggest natural-gas producer, is seeking payment from EON SE and BASF SE after boosting reserves at a joint project in Siberia, according to two people with direct knowledge of the matter.

Gazprom is claiming “more than 1 billion euros” ($1.35 billion) from EON, Germany’s biggest utility, and Wintershall, an oil and gas unit of BASF, one of the people said. The partners are in talks to try to sort out a “dispute and misunderstanding” about the Yuzhno-Russkoye field’s reserves, the other person said.
