| November 2015 | Approval of the project proposal for the period of 01.01.2016 to 31.12.2018 |
| August 2015 | Submission of a R & D proposal: "Thermal water circulation in the deep borehole Horstberg Z 1 - Characterization of an artificially created heat exchanger and geochemical investigations" |
| February 2015 | Application for a permission to conduct research for geothermal energy at the mininig authority (LBEG) |
| July 2009 - April 2016 | July 2009 - April 2016 - The Horstberg Borehole was temporarily closed. |
| May - July 2009 | Different types of the production tests |
| Dec. 2008 - Mar. 2009 | Removal of the leaky packer in the borehole. Installation of a new packer. Re-perforation of the Solling sandstone. (Rig) |
| September 2007 | Low-rate injection test to determine the hydraulic properties of the induced fracture and Detfurth sandstone. |
| June 2006 - March 2007 | Production and injection tests separately from the sandstone formations: Detfurth and Solling (logging winch, gauge, production test) |
| 2005/2006 | Enlarging of the drilling site as a permanent test field (High-pressure pumps, pump chamber for U-pump, logging winch, container, etc.) |
| Nov./Dec. 2004 | Packer setting in approximately 3770 m depth; Circulation between Detfurth (injection) and Solling (production) |
| Jan./Febr. 2004 | Cyclic production and injection tests on a daily and weekly basis (Scheme, group picture) |
| Oct./Nov. 2003 | Massive water fracturing in the Detfurth sandstone at approx. 3780m depth (Drill site, visit of BGR President) |
| September 2003 | Partial filling of the borehole below 4100 m / sealing of the gas bearing formations (Workover rig, Drilling site) |
| July 2003 | Transfer ceremony of the well Horstberg Z1 to BGR |
