ITALY: ENEL GREEN POWER (1989-2019)

Newpark has drilled over 205,000 meters of geothermal wells in Italy since 1982 including areas with presence of H2S & severe losses. Our latest project involved drilling an ultra-hot geothermal well with BHST close to 600° C – exacerbated by the development of a high-pressure gradient that required a 1,6 sg MW – using Ilmenite as weighting agent to achieve the required MW without any sagging issues.

ICELAND: LANDSVIRKJUN (2009)

A local power company was operator of the Icelandic Deep Drilling Project consortium driven by Statoil IDDP-1 well – Krafla field. The hottest and most productive geothermal well in the country required drilling through the first reservoir to meet the deeper one with critical BHST at 2100m. After successfully drilling through the basaltic formation the operator would now like to drill IDDP-3 well after feedback on our Descramble well experience characterized by critical BHST of over 550°C.
