Hydrogen and helium seeps have been reported worldwide, which may indicate large reserves within the subsurface. However, generation of hydrogen and helium is complex; poorly understood and constrained for both generation processes and migration. One source of native hydrogen is ultramafic rocks, which have experienced serpentinization together with water radiolysis. In contrast, helium generation occurs as the result of the radioactive decay of uranium and thorium present within radiogenically enriched basement. An exploration tool, dedicated to identifying areas with the geological settings and conditions favourable for native hydrogen and helium generation, has been developed and tested. Several databases have been created and integrated as part of this study (geological and geochemical generation models) to support and focus the search for both hydrogen and helium. Machine learning algorithms which extract value from geospatial data types for detecting various accumulations have been implemented. The first machine learning results demonstrate the significant value in integrating data and machine learning for high grading areas more conducive to accumulating hydrogen and helium.<\/jats:p>","DOI":"10.1144\/sp547-2023-49","type":"journal-article","created":{"date-parts":[[2024,2,2]],"date-time":"2024-02-02T10:17:45Z","timestamp":1706869065000},"page":"527-534","update-policy":"https:\/\/doi.org\/10.1144\/crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["A new exploration tool in the search for native hydrogen and helium"],"prefix":"10.1144","volume":"547","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-5290-4422","authenticated-orcid":false,"given":"Carolina","family":"Olivares","sequence":"first","affiliation":[{"name":"CGG, Llandudno","place":["North Wales, UK"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jennifer","family":"Findlay","sequence":"additional","affiliation":[{"name":"CGG, Llandudno","place":["North Wales, UK"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ranald","family":"Kelly","sequence":"additional","affiliation":[{"name":"CGG, Llandudno","place":["North Wales, UK"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Simon","family":"Otto","sequence":"additional","affiliation":[{"name":"CGG, Llandudno","place":["North Wales, UK"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Max","family":"Norman","sequence":"additional","affiliation":[{"name":"CGG, Llandudno","place":["North Wales, UK"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Cairns","sequence":"additional","affiliation":[{"name":"CGG, Llandudno","place":["North Wales, UK"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1881","published-online":{"date-parts":[[2024,3,22]]},"reference":[{"key":"e_1_3_6_2_1","doi-asserted-by":"publisher","DOI":"10.2138\/rmg.2002.47.12"},{"key":"e_1_3_6_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.chemgeo.2012.07.003"},{"key":"e_1_3_6_4_1","doi-asserted-by":"crossref","first-page":"33","DOI":"10.2138\/gselements.16.1.33","article-title":"The behavior of H2 in aqueous fluids under high temperature and pressure","volume":"16","author":"Bazarkina E.F.","year":"2020","unstructured":"Bazarkina, E.F., Chou, I.M., Goncharov, A.F. and Akinfiev, N.N. 2020.
