Cavern storage for the natural oil reserve
In 1968, drilling operations started at the Rüstringen salt dome and 35 salt caverns were leached as part of the national crude oil reserve. 7 million m³ of crude oil are stored in the caverns. To maintain the existing storage volume, a re-leaching project was started in 1998. The former KBB and later KBB UT provided support for the project, in particular with respect to planning.
In 2008, a new well was drilled to expand cavern capacity. KBB UT has been supervising the solution mining activities since April 2009 and will continue to do so until a volume of 1 million m³ has been reached.
NWKG mbH, a wholly-owned subsidiary of the Petroleum Stockholding Association, is planning to drill six cavern wells on the Zechstein formation salt dome in 2012.
