The project concerns the preparation for deep drilling and aims at solutions so that casings can withstand the strain that arises when high-temperature wells heat up. This is to be done, among other things, by examining cementing with "foam cement", a light and flexible cement that reduces the load on the casing. A method will be developed for releasing the pressure that builds up between casings (ÍSOR), corrosion protection by cladding will be specially examined, and corrosion tests will be carried out at the surface and down the well with a logging wire (ÍSOR). An integrated casing system designed to withstand supercritical conditions (including the use of expansion joints) will be tested in experiments at SINTEF in Norway, which also handles the simulation of boreholes.

About the project
Deep sampling will be used to obtain samples at interesting veins under hot conditions (ÍSOR), and the deep sampler that ÍSOR is developing in the REFLECT project will be used.
Collaboration and funding
The project is funded by the European Union's research and innovation programme, Horizon 2020.
Partners alongside ÍSOR: ON Power (lead), Orkuveita Reykjavíkur, the GEORG research cluster, Hornet Laser Cladding B.V., SINTEF, TWI Ltd., Technovative solutions Ltd., Curistec, Consorzio per lo sviluppo delle aree geothermiche.
ÍSOR project manager: Gunnar S. Kaldal.
