Despite being powerful levers to democratize digital technologies in many scientific domains, open-source projects still raise limited interest outside computer science circles. For instance, the ELK open-source framework is increasingly employed in various industries to manage and screen large collections of data and unstructured documents, but it remains under-exploited by the geoscience community. Consequently, in this study, we appraise the potential of this framework to browse and manage geoscience knowledge in two practical situations, corresponding to the routine work of exploration teams in an energy resources company. First, the ELK stack is combined with other open-source tools in a dedicated application architecture. Then this architecture is customized to address each use case more specifically, thus assessing its flexibility and versatility. Our conclusions are very positive about the capacity of the framework to considerably facilitate the handling of massive bases of geoscience knowledge, such as the documents capitalized in past exploration studies or the well information accumulated on mature fields. This work also illustrates how open-source projects can contribute to the digital transformation of subsurface-related industries, as geoscience professionals can rapidly develop solutions adapted to their concrete needs and unlock significant efficiency gains in their daily work.
