摘要:With sedimentary basins offshore East Greenland yet to be drilled, the onshore Jameson Land Basin (Surlyk 2003) provides a window into the nature of potential Jurassic source-rock sequences in offshore basins. Understanding the thermal history and maturity development in the onshore sequences can therefore provide unique insights into the prospectivity of the offshore basins. The Jameson Land Basin has itself been the focus of hydrocarbon exploration by a group of concessionaries with Atlantic Richfield (ARCO) as operator, but in 1990 the group decided not to continue exploration (Christiansen et al. 1992; Mathiesen et al. 2000). One of the main geological risks that ARCO critically assessed was the thermal maturity of their main target, the Upper Permian carbonates, since earlier studies had concluded that Tertiary exhumation had removed up to 3 km of Cretaceous sediments and Paleocene–Eocene volcanic rocks across the basin (Christiansen et al. 1992). Currently, Greenland Gas and Oil A/S and Nunaoil A/S hold a hydrocarbon exploration and exploitation licence across much of the Jameson Land Basin (www.govmin.gl).
