Well completion report: Ravn Pynt-1 fully cored borehole, Store Koldewey, Northeast Greenland. Contribution to Petroleum Geological Studies, Services and Data in East and Northeast Greenland

The Ravn Pynt-1, GGU 517009, fully cored borehole was drilled to test the succession of Middle Jurassic sandstones exposed in southern Store Koldewey. The borehole was drilled during the summer of 2017 at Ravn Pynt (“Pynt” = small promontory/cape, “nose”), southern Store Koldewey (Figs 1, 2).

The borehole was drilled by GEUS as part of the ongoing GEUS-industry collaboration “Petroleum Geological Studies, Services and Data in East and Northeast Greenland”, however, with participation exclusively by companies holding an exploration license offshore Northeast Greenland. Hence, the borehole was drilled on behalf of a consortium including three groups holding licenses for exploration offshore Northeast Greenland, represented by the operating companies Chevron, and ENI.

The objective was to test the Middle Jurassic sandstone succession exposed in southern Store Koldewey, represented by the Pelion Formation (Surlyk 2003 and references therein), in order to obtain data on the petroleum reservoir properties of this unit, which is expected to be present in the offhore license areas as well.

The Ravn Pynt-1 borehole was spudded on July 30th 2017 and completed on August 2nd 2017 at a total depth of 116.4 m, at which depth drilling had to be suspended since technical problems and the nature of the formation precluded further drilling. The borehole was planned to reach a depth of more than 150 m, which, however, proved impossible to reach. The total core recovery was slightly less than 95%.

The borehole was abandoned as an open hole.

For technical reasons borehole logging in the field was not attempted.
