| Abstract | The Berlín Geothermal Field (BGF) is a high-temperature geothermal system located in the southern flank of the Central Graben and the northwestern sector of the Berlín-Tecapa volcanic complex in Usulután, El Salvador. As one of El Salvador's primary geothermal resources, BGF currently operates with an installed capacity of 109.2 MWe through three condensing units – two 28.1 MWe units operational since 2000, and one 44 MWe unit since 2007 – and a 9 MWe binary unit added in 2009. The field's 45 wells include 15 production wells, 24 injection wells, and one pressure monitoring well; the remaining wells are inactive. In 2023, BGF contributed approximately 11.08% of the nation's total electricity generation, highlighting its significance as a renewable energy source. This study enhances the understanding of BGF through an integrated analysis of physical properties and the development of two complementary 3D models: (1) an updated conceptual model incorporating 3D-density data, seismic tomog |
