Wintershall Drills Duster at Rheiderland Z 1 Well

That extra bit of luck always required when exploring for oil and gas on this occasion failed experts from Wintershall AG and their partners on the Rheiderland Z 1 drilling site west of Bunderhee in Leer district. In the rock formations which are described by experts as "Rotliegend Sandstein" (Early Permian sandstone), geologists had expected to find a natural gas source at a depth of around 3820 meters: the finely porous rock deposit under exploration, however, proved to be empty of natural gas.

The erection of the drilling site was completed at the end of February 2003. Drilling operations commenced in October. The now completed, slightly inclined drilling shaft has a final depth of 4265 meters. Analysis of the drilling cores and other examinations in the drilling hole confirm the findings: there is no gas in Rheiderland Z1. In accordance with the conditions imposed by the public authorities the drilling shaft has been filled section by section with cement. The 58 meter-high drilling rig supplied by KCA-Deutag is still being serviced and will be dismantled in the next few weeks. Official supervision of the drilling site is being carried out by the Meppen offices of the Clausthal-Zellerfeld state mining authority.
