May 2006Seismic profile in Hannover (seismic truck, seismic truck)
January 2006Approval of the overall operation plan
February 2005Positive external review of the achieved results in Horstberg – Starting point for “Hannover” (aerial photograph)
TimeMilestones Well Horstberg Z1
September 2007Low-rate injection test to determine hydraulic properties of the fracture and the Detfurth-sandstone
June 2006 - March 2007Productions – and injection tests from/in the horizons Detfurth and Solling, seperately (Logging winch, sensor preparation, injection test)
2005/2006Upgrading of the site to a permanent test site (High pressure injection pumps, Submersible pump, Pump chamber, Logging winch, Container…)
Nov./Dec. 2004Installation of a packer at 3770 m, Circulation between Detfurth (injection) und Solling formation (production)
Jan./Febr. 2004Cyclic production and injection tests on daily and weekly basis (scheme, Wellhead Pressure and Flowrate, crew)
Oct./Nov. 2003Massive waterfrac in the Detfurth sandstone formation at about 3780m depth (test site, Wellhead Pressure and Flowrate, Visit of the BGR President)
September 2003Plugging the well below 4100 m / Separation of the gas bearing formation (Workover Rig, test site)
July 2003Handing over of the well Horstberg Z 1 from EMPG to BGR
