Geothermal project developers are aware of the importance of risk mitigation during the most important phases of their development. Successfully connecting the well to the geothermal aquifer is amongst the most important tasks undertaken during the project implementation. This will determine the success of the whole project.
Owing to the long history of geothermal utilization in Iceland, Mannvit has amassed significant expertise and experience in this unique field, which is not directly transferable from other industries. Mannvit offers 40 years of experience in providing engineering services for geothermal drilling as well as acting as the client’s representative during third party drilling.

Project example:
Iceland Deep Drilling Project (IDDP)
The IDDP consortium includes: Sudurnes Regional Heating Company, National Power Company (Landsvirkjun), Reykjavik Energy, the National Energy Authority of Iceland and Mannvit Engineering.
The consortium is preparing the drilling of a 4-5 km deep borehole into one of its high-temperature hydrothermal system to reach 400-600º C supercritical hydrous fluid at a rifted plate margin on the mid-oceanic ridge.
Mannvit services for IDDP:
- Well design
- Drilling technology
- Study of technology for fluid handling and evaluation
