The borehole was drilled as the first of three boreholes that in combina- tion were designed to provide full coverage of the Upper Jurassic – Lower Cretaceous petroleum source-rock suc- cession in eastern Greenland. The remaining two bore- holes, Rødryggen-1 and Brorson Halvø-1, were drilled on Wollaston Forland in 2009 and 2010, respectively, and the results from these boreholes will be published in a companion volume. The objectives of the drilling campaign were fulfilled, demonstrating that continuous sedimentation of oil-prone petroleum source rocks took place in eastern Greenland over a period of c. 13 million years from the Oxfordian to the Ryazanian, with the Blokelv-1 succession representing the older, Oxfordian– Volgian part of this interval. The drilling campaign was carried out as one of a num- ber of projects within the framework of a multi-client col- laborative programme between GEUS and a long list of petroleum companies entitled Petroleum Geological Stud- ies, Services and Data in East and Northeast Greenland. This collaboration was initiated in 2007 and is ongoing at the time of writing with more than 20 participant com- panies, a subset of which sponsored the studies presented herein; for contractual reasons, these companies can- not be named. The GEUS–industry collaboration was initiated in recognition of the need for new and better data on many aspects of the petroleum geolog y of east- ern Greenland prior to an anticipated licensing round of offshore North-East Greenland. The Circum-Arctic Resource Appraisal (CARA), undertaken by the United States Geological Survey (USGS), also played an impor- tant role in defining the priorities of the collaborative agreement by directing attention towards specific sub- jects in need of investigation. Licensing rounds in 2012 and 2013 resulted in the award of five licences. Based on the results of these activities in eastern Greenland, a large number of scientific papers have been published since 2008, and more are expected as confiden- tiality clauses expire. This volume is, however, the first GEUS Bulletin to be published as a direct consequence of the GEUS–industry collaboration. Jørgen A. Bojesen-Koefoed © GEUS, 2018.
