Shallow core drilling of Upper Permian and Upper Triassic – Lower Jurassic potential reservoir rocks in central East Greenland

Abstract

The aim of the 1988 shallow core drilling programme was to obtain unweathered and statistically representative samples of potential reservoir rocks to evaluate their diagenetic history. In the concession area held by ARCO (fig. 1) the youngest rocks expected to form a subsurface reservoir are the Upper Triassic - Lower Jurassic Kap Stewart and Neill Klinter Formations (Surlyk et al., 1986b; Stemmerik, 1988). At present, however, most interest is concentrated on the Upper Permian Wegener Halvø Formation (Surlyk et al., 1986a; Hurst et al., 1989) and, consequently, the programme focused on this formation in the type area (fig. 2). Additional drilling was carried out through the Kap Stewart Formation at a location dose to Constable Pynt (fig. 1).
