WorldWide Drilling Resource®

22 AUGUST 2025 WorldWide Drilling Resource® Zanskar’s New Step-Out Production Well Adapted from Information by Zanskar Geothermal & Minerals, Inc. According to Zanskar, geothermal energy is the best near-term option for clean, firm power at scale, and conventional geothermal resources are the key to scaling up any form of geothermal energy quickly and cost efficiently. Their strategy has focused on two main aspects: j Demonstrating the existence of many unexplored or poorly characterized sites that can be unlocked using advanced data collection methods and statistical tools, integrating natural and artificial intelligence with large geospatial datasets. j Showing these sites can generate significantly more energy than previously thought possible, by accurately accounting for subsurface uncertainty, collecting targeted data, and making informed drilling decisions. Field teams have spent three years collecting data under difficult conditions, and their efforts have paid off with the discovery of many previously unknown sites, confirming the first part of their thesis. The second part of their thesis, which involves drilling full-size production wells, has been more challenging to prove due to the increased capital and permitting requirements. The company is confident the majority of hydrothermal resources can exceed their historical production levels, thanks to advanced tools and technologies that facilitate more precise targeting and deeper resource utilization. When the Lightning Dock geothermal field in New Mexico was put up for sale due to underperformance, they seized the opportunity to acquire it and test their approach, leveraging the unique data sets they had already collected in the region. Just less than eight months after acquiring the field, the company is proud to announce the completion of their first step-out production well, which has produced remarkable results. Their strategic approach involved a directionally drilled large-diameter geothermal well, targeting a 7500 - 8000 foot deep fracture zone, and achieving their desired outcome. GEO Blasting by: R.A.
