Nestled in the heart of Mauritania lies a geological marvel awaiting exploration: The Taoudeni Basin Despite being one of the least explored basins globally, with only a few 2D seismic lines and five wells, this vast Upper Precambrian and Paleozoic sedimentary basin holds immense potential for oil and gas discoveries. Two petroleum systems are present: 1-Paleozoic Petroleum System: Source rocks: Silurian and Devonian Reservoirs: Ordovician 2-Neoproterozoic Petroleum System: Source rocks: Infracambrian Reservoirs: Stromatolic fractured limestones The basin's captivating geological history traces back to the Infracambrian era, stretching into the Carboniferous period, shaped by the tectonic forces of the Pan-African orogeny. This extensive zone of intracratonic subsidence has remained largely untouched, presenting a unique opportunity for those willing to delve into its depths. Exploration in the Taoudeni Basin is characterized by two significant periods: In the early 1970s, Texaco and Agip led the pioneering exploration efforts, conducting 2D seismic surveys and drilling wells such as Abolag-1 and Ouasa-1. Notably, Abolag-1 showcased the basin's potential with a gas flow rate of 13,600 m³/d, confirming the presence of a viable petroleum system. Exploration activity resumed in 2004, attracting companies like Total, Repsol, Sipex, and SMHPM. This period saw a substantial expansion of 2D seismic coverage to 15,000 km and the drilling of wells such as Ta8-1, Ta7-1, and Ouguiya-1, which revealed gas shows, further highlighting the basin's promise.
