The experimental results reveal that the analyzed samples display elastoplastic deformation and shear-enhanced compaction as primary plasticity mechanisms. These experimental findings contradict the expected linear elastic response anticipated before brittle failure, as reported in several studies on the geomechanical characterization of the Vaca Muerta formation. Therefore, we present a comprehensive laboratory analysis of Vaca Muerta formation samples showing their nonlinear elastic behavior and irrecoverable shear-enhanced compaction. Additionally, we calibrate an elastoplastic constitutive model based on these experimental observations. The resulting model accurately reproduces the observed phenomena, playing a pivotal role in geoengineering applications within the energy industry.<\/jats:p>","DOI":"10.3390\/computation11120250","type":"journal-article","created":{"date-parts":[[2023,12,11]],"date-time":"2023-12-11T06:56:00Z","timestamp":1702277760000},"page":"250","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Shear-Enhanced Compaction Analysis of the Vaca Muerta Formation"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-8933-6534","authenticated-orcid":false,"given":"Jos\u00e9 G.","family":"Hasbani","sequence":"first","affiliation":[{"name":"Vista Energy, Av. del Libertador 101 Piso 12, Vicente l\u00f3pez, Buenos Aires 1638, Argentina"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-0779-0983","authenticated-orcid":false,"given":"Evan M.
