Seismic survey vessel owner PGS is looking ahead with confidence after cutting its loss in the third quarter.

The Oslo-listed company said its net deficit to 30 September was $35.4m against $189.9m in 2017, as amortisation and impairments of its multi-client library fell.

Revenue dropped to $163.4m from $207.6m, however.

CEO Rune Olav Pedersen said he expected the higher oil price, improved cash flow among clients and an exceptionally low oil and gas discovery rate to benefit marine seismic market fundamentals going forward.
