Below we have collated papers being presented at the 2020+1 World Geothermal Congress that are related to supercritical and deep drilling projects underway internationally. This event did not go ahead in 2020, but in 2021 the congress evolved into five virtual events (March – July 2021), plus an in-person event in October 2021 in Reykjavík.

The abstracts for each paper/presentation are accessible and linked below, but the presentations are only open to those who have registered for the congress. The conference papers will be freely available at the close of the conference (October 2021) from the International Geothermal Association's conference database.

You can also freely view all the WGC opening ceremony presentations here.

The papers are grouped into the following: General; Geophysics; Geochemistry & Modelling; IDDP; Krafla.
