Summary: By integrating various methods in a study of Paleozoic and Triassic reservoir sandstones from the Ghadames-Illizi Basin, potential thermal effects on the pore network modifying diagenetic events were explored. Results suggest that a Tertiary heating overprint, particularly an Early Tertiary thermal event, better explains the data collected, significantly impacting the calculated age of cements precipitation in the studied reservoir rocks.

Summary: Raw phosphates in the Gafsa-Metlaoui phosphate basin are processed through wet processes at the Gafsa Phosphates Company to reach market grades. The enrichment process increases the P2O5 content by removing coarse and fine fractions. Analysis of the materials from the laundries revealed different compositions and elements concentrations, with fine wastes being more polluted with Cd, Cr, Zn, Pb, U, and the rare earth elements.

Summary: The study of Silurian hot shale in the Ghadames Basin in Africa revealed that the organofacies type is predominantly marine type B. The thermal maturation levels of the hot shale range from early to post-mature stages. The study indicates that the hot shale in the basin margins and depocenter is a potential sweet spot area for unconventional shale oil and gas play in the future exploration activities in western Libya, eastern Algeria, and southern Tunisia.

Summary: The Bonaparte Basin on the Australian North West Shelf has undergone multiple episodes of exhumation since the Palaeozoic, affecting the distribution of petroleum systems in the basin. Understanding the spatial and temporal distribution of exhumation can help optimize oil and gas targeting and identify potential subsurface locations for CO2 storage. Compaction and vitrinite reflectance analysis revealed that the southern Bonaparte Basin experienced an average of about 1.9 km of total exhumation, with different levels of exhumation in different areas throughout geological time.

Summary: The study on sediment cores from Monastir Bay revealed a long-term pollution with diverse anthropogenic sources. Local hydrodynamics played a role in controlling the distribution of pollutants, predominantly a mixture of pyrolytic and petrogenic sources. The Bay was considered to be a moderately to highly polluted area with potential ecosystem risks.

Summary: The Borno (Chad) Basin is an intra-cratonic rift basin located at the southwestern terminal of the West Africa Rift System. Despite reported low petroleum potential, oil seepages have been found from its oldest stratigraphic unit, the Bima Sandstone, posing challenges in classifying the basin's petroleum system elements and predicting the origin of the oil seepages. Structural analysis and petroleum system modeling have been employed to investigate the structural and hydrocarbon evolution of the basin, revealing a lack of key petroleum system elements due to uplift during the Late Cretaceous, causing sediment diversion and hindering conventional hydrocarbon entrapment.

Summary: This study identified karst areas and groundwater potential in carbonate rocks in Tunisia using a GIS-based predictive model. Three karst systems of different ages were studied, and the dominant groundwater type is calcium-bicarbonate-magnesium and sulfate. The concentration of total dissolved solids (TDS) varies across different regions. The isotopic composition and 14C activities of the groundwater indicate a rechargeability period related to past colder climatic conditions.

Summary: This study presents a comprehensive geochemical analysis of source rock intervals in the Mandawa Basin, Tanzania, to determine organic matter types and quality. The results show that the organic matter richness is low and the potential for oil generation is generally fair. The study also reveals high spatial variability in organic matter quality in the region.

Summary: The post-snowball Earth world is favorable for the development of hydrocarbon source rocks and potential petroleum exploration. In the Southern Amazon Craton, there is a remarkable example of post-Marinoan rocks which act as unconventional petroleum reservoirs. This study aims to understand the paragenesis sequence and control factors of these reservoir rocks dominated by microbialites. The findings enhance our knowledge of syndepositional diagenesis in microbial-induced reservoirs and provide a guide for future petroleum exploration.

Summary: The Southern Gabes aquifer in southeastern Tunisia is a vital water source for various socio-economic sectors, but it is facing pollution risks due to excessive abstraction and human activities. This study assesses groundwater vulnerability and maps out the areas at risk. The results show a high pollution risk in the study area, highlighting the need for proactive measures to protect and sustainably develop the groundwater resources.
