Facies mapping and reservoir evaluation of the Upper Permian Wegener Halvø Formation in Wegener Halvø, East Greenland

Abstract

Field work was carried out from 17 July to 3 August by a joint group from ARCO, AGIP and GGU to evaluate the reservoir potential of the Upper Permian limestones in Wegener Halvø (fig. 1). The group was based south of Paradigmabjerg (fig. 1) and had a Bell 206 helicopter available tull-time during the entire period. Logistic support was provided by the ARCO base at Constable Pynt. The Upper Permian limestones in the Wegener Halvø area have been investigated previously by GGU (Stemmerik, 1979; Surlyk, 1983; Surlyk et al., 1984a,b, 1986a; Hurst et al., 1989). Diagenetic studies of the limestones (Scholle, 1986; Hurst et al., 1989) indicate that reservoir properties are expected mainly to occur in the bryozoan-cement mounds of the Wegener Halvø Formation. Accordingly, the 1988 programme concentrated on more detailed studies of these mounds and included a shallow drilling programme conducted by GGU (see Christiansen & Stemmerik, 1989).
