Oasis Sarl Innovative hydrogeophysics for sustainable access to water in Africa

OASIS is a Beninese scientific consulting firm specialized in hydrogeophysics for water access in sub-Saharan Africa. In crystalline basement areas, where groundwater is far scarcer and harder to mobilize than in sedimentary zones, OASIS deploys cutting-edge geophysical methods (RMP, ERT, TDEM, EM34…) to secure borehole siting and reduce drilling failure rates.
Founded in 2022, OASIS has grown from 3 to 9 staff and reached 45.7M FCFA in revenue in 2025 (its first profitable year). Already operating in Benin, Burkina Faso, Côte d’Ivoire, and Togo, OASIS works with public water agencies (GIZ, OMILAYE) and international firms (GOPA Infra) and NGOs.
Our competitive edge: proprietary high-end equipment, scientific-grade deliverables, and a founder with a PhD and 11 years of field experience in hydrogeophysics. We are now seeking to certify (ISO 9001), expand regionally, and build North-South partnerships with European and North American firms seeking a solid local anchor in West Africa
