Abstract

Summary

A greenhouse project in the southeastern part of the Netherlands, wants to use geothermal energy. The subsurface consists of different types of sediments with several unconformities and NW-SE oriented faults. Previous research showed that the Lower Volpriehausen Sandstone Member has the most promising hydraulic properties and temperature for geothermal application. However, the thickness of the Lower Volpriehausen Sandstone Member is limited. Given the limited thickness and related low flow rate a vertical well is not economical feasible in this case. To increase the production rate a choice was made for a horizontal well, as such a well is several times more productive than a vertical well. For horizontal wells the value of the vertical permeability is of great influence on the flow rate. This paper describes how a realistic vertical permeability has been determined and the effect on the production of geothermal energy.
