Lightning Dock Geothermal Field Data Package, Hidalgo County, New Mexico

Published by Zanskar geothermal & minerals inc | Department of Energy | Catalog Last Checked: August 21, 2026 at 05:10 AM | Dataset Last Updated: August 20, 2026 at 11:11 PM
This submission is a curated geoscience, well and plant-operations data package for the Lightning Dock geothermal field in the Animas Valley, Hidalgo County, south-western New Mexico, a liquid-dominated system produced for binary (ORC) power generation. It covers well-by-well data for 41 wells, including logs, drilling and completion records, flow tests, pressure-temperature surveys, production and injection time series, and directional survey compilations; inter-well tracer test campaigns from 2012 through 2019; geophysics comprising magnetotellurics, aeromagnetics, gravity and LiDAR; the daily plant operations record covering January 2014 to August 2026; shallow groundwater monitoring; GIS layers with a QGIS project that loads them; and fluid and gas geochemistry. Read the included data package guide first: it describes each dataset, the naming conventions the files follow, and the units. Two prerequisites are worth noting. The daily operations table carries one row per source spreadsheet rather than one row per day, so it should be read alongside its accompanying column-description PDF before analysis. The GIS project requires QGIS and uses paths relative to its own folder, so that dataset should be kept intact rather than having individual layers moved. Well identifiers are consistent throughout, so logs, tests, operations columns and GIS well layers can be joined on the well name.

Six field-wide tables sit alongside them: well trajectories and collar coordinates (2,777 survey stations, 29 wells), downhole logger pressure and temperature (2,224,582 readings, 12 wells, 2014-2021), pressure-temperature-spinner profiles against depth (1,759,715 readings, 19 wells, 1984-2025), manual wellhead pressure rounds (16,739 readings), and catalogues of every wireline log (515) and every well test (90) giving the file each one lives in. Depths in feet, temperatures in Fahrenheit, pressures in psi. "

Concentrations in µg/L. Results below the laboratory detection limit carry that limit in the value column with a censored flag set, and must not be read as zeros -- 36% of results are censored."

A PDF beside the table describes every column. The table carries one row per source daily report rather than one row per calendar day, so read it with that PDF before analysis.

Includes mapped and inferred faults, the Animas Valley fault trace, Muir Caldera ring fractures, aeromagnetic contours and flight lines, gravity stations and Bouguer contours, resistivity station lines, a shallow temperature anomaly, six interpolated water-chemistry surfaces, and production, injection and temperature-gradient well locations. NAD83 / UTM zone 12N (EPSG:26912), except the USGS Quaternary faults layer in geographic degrees. The QGIS project uses paths relative to its own folder, so keep the folder intact rather than moving individual layers."

Two ThermoChem laboratory reports and a 2025 gas analysis workbook are included. Units are as reported, with a unit column on every row -- mixed mg/kg, mg/L, µg/L, ppm and per-mil. Results below the detection limit carry that limit with a censored flag and must not be read as zeros. "
