April 2, 2019: Oslo, Norway, PGS routinely releases information about 3D vessel utilization after the end of each quarter.

Summary of vessel utilization:

           
The Q1 2019 vessel statistics includes eight vessels. All cold-stacked* vessels are excluded from the statistics.

PGS will release its Q1 2019 results on Thursday April 25, 2019, at approximately 8:00am Central European Summer Time (CEST). A corresponding presentation is scheduled for 09:00am CEST the same day.

*The term "cold-stacked" is used when a vessel is taken out of operation for an extended period of time. Costs are reduced to a minimum, with the vessel preserved for a long idle time, all or most in-sea seismic equipment removed from the vessel, and typically the Company does not have available crew to operate the vessel.
