Boreholes in Greenland

The dataset contains basic information on the location of onshore and offshore drillholes in Greenland established for scientific research as well as mineral, oil and gas exploration. The dataset functions as a geographic reference layer and, where available, includes links to reports or summary sheets representing the original source of information. The dataset covers drillholes established between 1948 and 2019 and is subject to continuous updates as new information becomes available through scientific publications, press releases and company documentation.

Supplemental Information
The dataset functions as an index and reference dataset representing generalised drillhole locations. Coordinates and associated information may vary in precision depending on the original source. The dataset does not constitute a legal definition or detailed technical documentation of individual drillholes. For detailed information on drilling operations, core descriptions or technical data, the original sources must be consulted.

Statement
The dataset was established through the integration of two primary data sources. The first source is the GREENCORE database, previously used for registration of mineral exploration drill cores stored at the former Bureau of Minerals and Petroleum drill core facilities in Greenland, now under the Government of Greenland (MMR). The second source consists of Greenlandic boreholes from the SAMBA database, including hydrocarbon exploration wells and other drill cores stored at the GEUS core repository in Copenhagen. The dataset represents a compilation of existing registrations and does not contain primary drilling data or complete borehole logs.
