ARCTIC MARINE SEISMIC ACQUISITION FEASIBILITY: A CASE STUDY NORTHEAST OF GREENLAND
The Northeast Greenland Shelf is one of many marine arctic areas with potential for significant hydrocarbon accumulations. However, to date, multichannel seismic data are missing north of 73 degrees due to Arctic pack-ice which usually covers the Northeast Greenland Shelf. Seismic data have become a prerequisite to drilling, particularly in expensive arctic areas. Noise due to operations on pack-ice can limit successful seismic acquisition. Hence, seismic acquisition feasibility can be the critical factor limiting future arctic oil exploration. The object of this study is to evaluate the feasibility of various concepts for acquiring multichannel seismic data from 73 to 80 degrees north in water depths less than 500 metres. These concepts include ice-reinforced seismic ships, submarine seismic, acquisition from floating ice, and land-fast-ice acquisition. This report concludes that it is feasible to acquire multichannel seismic data over Greenland's Northeast Continental Shelf north of 73 degrees.
