Petroleum Geo Services : PGS plans to refinance debt later this year - CEO

OSLO (Reuters) - PGS, the world's largest seismic surveyor, plans to refinance its debt later this year, Chief Executive Rune Olav Pedersen told an energy conference in Oslo on Wednesday.

PGS called off a planned $675 million (546.25 million pounds) debt issue in June this year, blaming rising market volatility at the time.
