Greenland Margins

The North Greenland continental margin only locally appears to contain enough sediments to either generate sufficient methane or host a HSZ. However, this area is little explored due to difficult environmental conditions and its remoteness. Thick sediments in intracratonic basins on the East Greenland shelf (Jackson et al., 1991) may contain geological petroleum traps similar to those proven by drilling in the Troms-Hammerfest basins.

Figure 4. Section of seismic reflection profile, based on a 2-liter airgun and a 6-channel streamer located at the Svalbard margin. The arrows mark the locations of the HF-OBH stations 5 and 6 at the sea floor. A strong BSR occurs at a depth of 0.25 s TWT bsf. The BSR parallels the sea floor, crosses the discordant sedimentary strata and is characterized by high amplitudes. Below the BSR the base of gas-bearing sediments is marked by the BGR (from Posewang and Mienert, 1999b).
