Harnessing Extreme Environments:

NSM Solutions for Geothermal Energy

Geothermal energy stands as a cornerstone of the transition to sustainable power. Yet, it operates at the extreme—battling intense heat, aggressive brine chemistry, and complex mineralogy that relentlessly threaten operational efficiency, asset integrity, and profitability.

The very source of geothermal energy—superheated, mineral-rich brine—poses its greatest operational challenge. It deposits tenacious silica and silicate scales that choke wellbores, restrict flow in surface equipment, and cripple power output. This is compounded by corrosion and the deposition of metal sulfides, creating a perfect storm of operational challenges.

These are not simple problems, and they demand more than generic chemical solutions. They require advanced, targeted science.
