Shallow compaction data of the Groningen gas field and other locations in the Netherlands – period 1970 to 2021.

This dataset comprises shallow (0 to 400 meter) compaction data obtained in various locations across the Netherlands, including the large Groningen gas field in the NE Netherlands. Data were obtained in 14 dedicated shallow compaction wells in Groningen, 1 well in Friesland (N Netherlands), 1 well in Drenthe (N Netherlands) and 4 wells in South Holland (SW Netherlands). This dataset includes a) spirit levelling data, obtained every six months from 1970 to 2002, and b) cable stretch measurement data, obtained daily from 1970 to 2021. The first dataset is obtained by measuring the relative heigh... Mehr ...

This dataset comprises shallow (0 to 400 meter) compaction data obtained in various locations across the Netherlands, including the large Groningen gas field in the NE Netherlands. Data were obtained in 14 dedicated shallow compaction wells in Groningen, 1 well in Friesland (N Netherlands), 1 well in Drenthe (N Netherlands) and 4 wells in South Holland (SW Netherlands). This dataset includes a) spirit levelling data, obtained every six months from 1970 to 2002, and b) cable stretch measurement data, obtained daily from 1970 to 2021. The first dataset is obtained by measuring the relative height between two points, or bolts that are anchored into a building, ground surface or the shallow compaction measurement device, and gives insight to the compaction of i) the Holocene formations (5-20 meter from surface) and ii) the underlying Pleistocene and top Tertiary formations, down to 400 meter. The cable stretch method measures the compaction of the Pleistocene + top Tertiary formations down to 400m depth, via a cable that is connected to an anchor weight, positioned at the bottom of a well. With reference to the data obtained in the Groningen gas field, the field producer NAM (Nederlandse Aardolie Maatschappij) originally collected these data to determine autonomous, natural compaction, with the aim to correct the total surface subsidence signal with this component to quantify subsidence caused by gas extraction. This dataset is further accompanied by a 1994 report, written in Dutch, on the shallow compaction data, and a document in English, providing key details needed to understand and use the data.
