The Cretaceous deep-water fans of the Tano Basin, Côte d’Ivoire and Ghana, have proven to continue to yield significant discoveries. Earlier this year Eni announced the Murene 1X well discovery, subsequently named Calao, estimated to hold up to 1.5 billion barrels of oil equivalent. Last year Murphy Oil Corporation acquired a 90% stake in several blocks, including the Paon discovery (made by Anadarko, now Oxy in 2012). Eni also discovered Baleine in 2021/22. In addition the Jubilee and TEN discoveries made by Kosmos Energy and Tullow Oil over a decade ago hold significant volumes. I compiled some information from public sources to see how the overall architecture of the system relates to these discoveries. The discoveries are made in primarily Upper Cretaceous turbidite channel-lobe systems, which form substantial fan complexes. The deposition and architecture of these is thought to have been influenced by the tectonic development of the West African Transform Margin (Cronin et al., 2023, Nemčok et al., 2023, Burrell 2024). The discoveries have all been made inboard of the continent ocean boundary, although the recent Orange Basin discoveries made by TotalEnergies, Shell and partners may point towards potential further out, where there are several available and pending blocks. It will be interesting to see how exploration continues along this part of the margin, who picks up the pending blocks, and if the prolific plays can be proven further outboard. #exploration #production #development #seismic #oilandgas #energy #geology #geophysics #clastics #carbonates #plays #riftbasins #structuralgeology #petroleum #hydrocarbons #oil #gas #deepwater #turbidites #channels #lobes #channelcomplexes #basins #cretaceous #stratigraphy #wells #gis #qgis #africa #cartography #mapping #maps #namibia #westafrica #transformmargin

Significance of geological structures in localization of hydrothermal alteration zones in western part of Rwanda: implications to mineral Exploration. Hydrothermal alteration zones are highly important and have always attracted the attention of exploration geologists due to their high potential of containing economic minerals and ore deposits that are critical for various industries. They are often related to causative major geologic structures that act as the passage for the hydrothermal solutions which are the main player in the origination of the hydrothermal alteration zones.Consequently, the geologic structures are very important to be considered while investigating the hydrothermal alteration zones. For instance The western part of Rwanda is known for containing a lot of mineral resources; alot of which are related to hydrothermal alteration. In western part of Rwanda, it is known to be mineralized area through the application adopted by remote sensing and geophysical data providing maps for investigating hydrothermal alteration zones in relationship to geological structures. In mineral exploration, hydrothermal alteration zones often correlate with geological structures such as faults, fractures, and intrusions. in western part of Rwanda,these structures act as pathways for hydrothermal fluids, facilitating the alteration of surrounding rocks. Generally As fluids move through these structures, they alter the mineralogy and chemistry of the host rocks, creating distinctive alteration zones that can signal the presence of valuable mineral deposits. Understanding the relationship between these alteration zones and geological structures in western part of Rwanda,helps geologists target exploration efforts more effectively, as the altered areas often coincide with ore bodies. Thus, geological structures significantly in that area influence the distribution and localization of mineral resources. #geologist

Little late to finding this, but for those now following. Findings on Research Conducted on Mali Hydrogen Reservoir. Gives some points to consider for current exploration efforts. A great piece of work from Dr. Omar Maiga et al. Public research like this is helpful to all explorers working through the best ways to model commercial potential as well as drill their exploratory wells for the data needed to characterize the discovery. We need more public research like this to increase the potential and speed of explorers making a commercial discovery so as to herald in new investment that is needed. While this is a better read for geoscientists there were a few key items that piqued my interest. 💡Natural hydrogen found in traps at shallow depth is the closest to matching oil and gas models and production techniques and the most economical to exploit. 💡 Other than data logging the neutron tool proved to be effective in identifying hydrogen. In this case it became the primary tool, though there are limitations with dissolved hydrogen at greater depths. 💡The reservoir continues to recharge itself via a dynamic system. In fact pressure increased after the well was drilled. The concept of modeling the dynamic system and recharge potential makes natural hydrogen very different from typical gas exploration and has economic significance. 💡Below 800 meters h2 appeared to dissolve in water at those pressures. This idea will impact decisions made by explorers and their modeling. It will likely require an surface and subsurface engineering solution. From what I have heard water handling is a key challenge those exploring the mid-continental rift are experiencing. 💡Leaves it open to the concept of degassing from depths with a theory on recharging occurring higher up where serpentinization was observed. #NaturalHydrogen #WhiteHydrogen #GeologicHydrogen #EnergyTransition #RenewableEnergy https://lnkd.in/g6M_DbZ8 .

Deep-seated #faults play a pivotal role in hydrocarbon #exploration and production due to their significance in facilitating #hydrocarbon #migration to potential reservoirs. These faults, which cut through the deep source rocks, create #pathways for the upward movement of hydrocarbons from their origin to accessible reservoirs. By intersecting both #clastic and #carbonate reservoirs, these faults serve as conduits, allowing hydrocarbons to #accumulate in commercially viable quantities. Moreover, the #juxtaposition of different rock types along these faults can create traps where hydrocarbons are trapped, enhancing reservoir potential. #Understanding the distribution and characteristics of these #deep-seated faults is therefore essential in the exploration and development of hydrocarbon #resources. A recent study sheds light on this crucial aspect with a seismic cross-section directed NNW-SSE from the #Southern #Abu #Gharadig basin in the northern Egyptian Western Desert. For those interested in delving deeper, the paper associated with this seismic cross-section can be accessed DOI: https://lnkd.in/dk4njuTc #Geology #PetroleumExploration #FaultSystems #HydrocarbonMigration #ResearchInsights

#ASXNews Chilwa Minerals is pleased to announce that, following the announcement of the HMS geophysical interpretation, it now provides details of the REE-related interpretation of the aeromagnetic and radiometric surveys completed at the Chilwa Project in southeast Malawi. 🔸High resolution aeromagnetics and radiometrics were flown over the entire Lake Chilwa Project, with the interpretation also assessing the rare earth elements (REE) and niobium potential of the project. 🔸There are over 12 known carbonatites mapped surrounding or within the project area at Lake Chilwa. 🔸The geophysical interpretation of the aeromagnetic and radiometric data has 46 targets that may represent carbonatites or alkaline intrusives plus one (1) dyke, which may be sources for rare earth elements and niobium mineralisation measuring approximately a 21 kilometre strike. 🔸Targets including the dyke, cover an area of approximately 31km2 in total, highlighting the prospectivity of the region. #CHW's Managing Director, Cadell Buss, commented: “The early (untargeted) drill results and the new geophysical interpretation give us significant confidence to commence a parallel exploration stream focused on the rare earth and niobium potential at the Chilwa Project. “We already know that the region is fertile for rare earth mineralisation with projects at various stages of development and the parental melt for the carbonatite was derived from an ancient depleted sub-continental mantle source, similar to the one that generated the carbonatites melts at Kangankunde. (Lindian Resources project). “Approximately 600 carbonatites have been discovered globally, and given the amount of targets that have now been identified, the prospectivity of the Chilwa Project has significantly increased and diversified into a multi commodity asset and we expect that the positive news flow generated by the Project will increase over the next 6-12 months.” VIEW full Announcement: https://loom.ly/rWLXXE8 #ChilwaMinerals #MiningNews #ASX
