“…The structural transects in the Tell FABT presented in this work and others (El Euchi et al, 2004;Aissaoui et al, 2016;Kiely and Tari, 2017;Khomsi et al, 2019 and emphasize the interest to undertake oil/gas exploration in the Maghrebides. In fact, two major petroleum systems are potentially productive in the Tell: the Pre-salt Paleozoic system and the Meso-Cenozoic system (Khomsi et al, 2019 and.…”

“…As emphasized earlier by Tari and Kiely (2017) for the Atlas FABT and its foreland basin and by Khomsi et al (2019) for the Tell and Atlas belt, the Paleozoic system is obviously a very interesting system to explore and drill: in this system the main source rocks are represented by the Devonian and Silurian hot shales (see Aissaoui et al, 2016;Tari and Kiely, (2017) and Khomsi et al, (2019). The structural transects presented in this work underline that the major regional seal of the Paleozoic system is represented by the Triassic salt levels (Figs.…”

“…The Triassic salt level represents a regional seal above the possible Paleozoic traps seated in the subsurface of the Tell. As emphasized by Kiely and Tari (2017) for the Atlas belt and by Khomsi et al (2019), the underlying Paleozoic inherited highs and anticlines should be sourced by the Silurian hot shales (Aissaoui et al, 2016;Khomsi et al, 2019). Unfortunately, the lack of deep seismic soundings and investigations still prevents characterizing the sub-salt traps certainly seated in the Paleozoic sequences and subsurface structures.…”

Structural styles of the Tellian fold-and-thrust belt of Tunisia based on structural transects: Insights on the subsurface oil and gas pre-salt plays

We present several structural transects throughout the internal part of the Tunisian Tell focusing on some representative structures and domains. We used also an interpreted seismic crosssection and a 3-D structural view to highlight the styles within the Tellian Units in the Fernana-Adissa allochthon domain. The structural style is mainly represented by active roof-thrust and duplex structures affecting the Mesozoic-Cenozoic sequences belonging respectively to the Infra-Kasseb and Kasseb Units. The main decollement thrusting layer is located in the Triassic evaporites while the roof thrust corresponds to the Upper-Cretaceous or to the Paleocene shaly levels. The structural transects allow to view that the Numidian Flysch unit presents different structural configurations and relationships with its subsurface supporting units; (1) it rests on an apparent stratigraphic contact above the underlying Kasseb nappe or even over pre-existing Triassic salt structures while elsewhere (2) it is detached above these infra-Numidian units reworking an originally downlap contact. The area is also characterized by important halokinetic movements controlling the overall architecture of the Tell fold and thrust belt that

“…The sedimentary section within the Ghadames (Berkine) ranges from Cambrian to the present and is approximately 7000 m (23000 ft) thick in the depocenter. The basin has experienced several tectonic events, which have modified its architecture and affected the petroleum systems and hydrocarbon pathways (Aissaoui et al 2016 ). The main petroleum systems of the Ghadames (Berkine)/Illizi Basin are represented by the Silurian Tannezuft hot shale source rock with Ordovician Djeffara and Silurian Acacus reservoirs, by Silurian Tannezuft hot shale with Kirchaou reservoirs, and by the Devonian Aouinette Ouinine Formation Member III source rock with Kirchaou reservoirs (Aissaoui et al 2016 ).…”

The Frasnian organic-rich shales of the Ghadames (Berkine)/Illizi Basin are termed “Argile Frasnienne Radioactive” in eastern Algeria and, in southern Tunisia, are part of ‘term III’ (Frasnian) of Aouinet Quenine Formation (Lüning et al 2003 ).…”

Crude oil exploration in Africa: socio-economic implications, environmental impacts, and mitigation strategies

et al. 2021

View full text Add to dashboard Cite

Crude oil exploration is a source of significant revenue in Africa via trade and investment since its discovery in the mid-19th Century. Crude oil has bolstered the continent’s economy and improved the wellbeing of the citizenry. Historically, Africa has suffered from conflicts due to uneven redistribution of crude oil revenue and severe environmental pollution. Advancements in geophysical survey techniques, such as magnetic and gravity methods, to seismic methods, have made the commercial exploration of crude oil possible for some other countries in Africa apart from Nigeria, Angola, Algeria, Libya, and Egypt. The occurrence of organic-rich, oil-prone Type I, II, and mixed II/III kerogens in sedimentary basins and entrapment within reservoir rocks with intrinsic petrophysical properties are majorly responsible for the large deposits of hydrocarbon in Africa. The unethical practices by some multinational oil corporations have resulted in social movements against them by host communities and human rights groups. The unscrupulous diversion of public funds, award of oil blocks, and production rights to certain individuals have impaired economic growth in Africa. The over-dependence on crude oil revenues has caused the economic recession in oil-producing countries due to plummeting oil prices and global pandemic. Most host communities of crude oil deposits suffer from a lack of infrastructure, arable soils, clean water, and their functioning capabilities are violated by crude oil exploratory activities, without adequate compensations and remedial actions taken by oil companies and the government. Thus, this review examines crude oil exploration in Africa and provides insight into the environmental and socio-economic implications of crude oil exploration in Africa. Furthermore, this report highlights some recommendations that may ensure ethical and sustainable practices toward minimizing negative impacts and improving the quality of life in affected communities.
