OSLO, Norway -- PGS has started acquiring 2D seismic for the Norwegian Petroleum Directorate (NPD) in Norway’s newly agreed maritime zone in the Barents Sea.
The vessel R.V. Harrier Explorer is performing the survey, the first time this area has been be systematically mapped. One 8,100-m (26,575-ft) long streamer is being towed, with spacing for the seismic lines varying from 5-15 km (3.1-9.3 mi).
The program will also feature PGS' GeoStreamer, a new technology that involves towing the streamer deeper in the water than is normal, so that the cable can withstand higher waves. This, PGS claims, makes the acquisition activity less weather-dependent and therefore more efficient.
Harrier Explorer has sailed from the Jan Mayen region between Norway and Iceland, where it has been acquiring more seismic data for NPD over three and a half weeks, with no weather delays.
The Barents Sea program starts with five SSE-NNW lines, followed by acquisition of a few lines in the north-south direction in order to complete the southernmost part of the area first.
NPD plans to complete acquisition of the seismic data next summer, allowing results to be ready in spring 2013.
