3D static modeling and CO2 static storage estimation of the hydrocarbon-depleted charis beservoir, Bredasdorp basin, South Africa
Afolayan, Blessing Ayotomiwa; Opuwari, Mimonitu; Mackay, Eric (Natural Resources Research, 2023)An essential greenhouse gas effect mitigation technology is carbon capture, utilization and storage, with carbon dioxide (CO2) injection into underground geological formations as a core of carbon sequestration. Developing ... -
Determination of total organic carbon content using Passey's method in coals of the central Kalahari Karoo Basin, Botswana
Mabitje, Mamphedi Sylvia; Opuwari, Mimonitu (2022)This paper focuses on determining total organic carbon (TOC) from boreholes in the Kalahari Basin, Botswana, using Passey's method. The Kalahari Karoo basin is one of several basins in southern Africa filled with Late ... -
The impact of detrital minerals on reservoir flow zones in the North Eastern Bredasdorp basin, South Africa, using core data
Opuwari, Mimonitu; Ubong, Moses Okon; Jamjam, Simamkele (MDPI, 2022)The present study uses core data to group reservoirs of a gas field in the Bredasdorp Basin offshore South Africa into flow zones. One hundred and sixty-eight core porosity and permeability data were used to establish ... -
Metal–metal correlation of biodegraded crude oil and associated economic crops from the Eastern Dahomey Basin, Nigeria
Mohammed, Saeed; Opuwari, Mimonitu; Titinchi, Salam (MDPI, 2022)The presence of heavy metals in plants from oil sand deposits may reflect mineralization resulting from petroleum biodegradation. Petroleum composition and heavy metal analyses were performed using thermal desorption gas ... -
New insights in the evaluation of reserves of selected wells of the Pletmos Basin offshore South Africa
Elamri, Samir; Opuwari, Mimonitu (One Petro, 2016)The area evaluated has similar structural styles and settings as the producing neighboring fields of F-A and E-M in the adjacent Bredasdorp basin Offshore South Africa. The main objective of this study is to create a ... -
An overview of trace elements in soils of Keana-Awe Brine-Fields, Middle Benue Trough, Nigeria
Sallau, Adamu; Momoh, Abuh; Opuwari, Mimonitu; Akinyemi, Segun; Lar, Uriah (Taylor & Francis: STM, Behavioural Science and Public Health Titles, 2017)The objective of this study was to determine the concentration of trace elements in soils of Keana-Awe brine-fields. Composite soil samples were randomly collected at a depth of 0–15 cm and were analysed for molybdenum, ... -
Petrophysical interpretation and fluid substitution modelling of the upper shallow marine sandstone reservoirs in the Bredasdorp Basin, offshore South Africa
Magoba, Moses; Opuwari, Mimonitu (Springer Nature, 2020)The fluid substitution method is used for predicting elastic properties of reservoir rocks and their dependence on pore fluid and porosity. This method makes it possible to predict changes in elastic response of a rock ... -
Sandstone reservoir zonation of the north-western Bredasdorp Basin South Africa using core data
Opuwari, Mimonitu; Dominick, Nehemiah (Elsevier, 2021)This study delineates sandstone reservoir flow zones in the north-western Bredasdorp Basin, offshore South Africa, using conventional core porosity and permeability data. The workflow begins by integrating sedimen- tology ... -
Shale-gas potential from Cretaceous succession in South Africa’s orange basin: insights from integrated geochemical evaluations
Opuwari, Mimonitu; Yelwa, Nura Abdulmumini; Mustapha, Khairul Azlan (Taylor & Francis, 2022)Shale sediments were collected from four Cretaceous stratigraphic units across four explorations well locations in South Africa’s Orange Basin and analysed to determine organic-matter characteristics, such as amount, ... -
Source rock evaluation of Afowo clay type from the Eastern Dahomey Basin, Nigeria: Insights from different measurements
Mohammed, Saeed; Opuwari, Mimonitu; Titinchi, Salam (Springer Nature, 2020)The Cretaceous Afowo Formation in the Eastern Dohamey Basin is characterized by an admixture of lithofacies ranging from sandstones, claystones, shales, clays, sand/shale, and sand/clay intercalations. The sandy facies, a ... -
Static reservoir modeling using stochastic method: A case study of the cretaceous sequence of Gamtoos Basin, Ofshore, South Africa
Ayodele, Oluwatoyin Lasisi; Chatterjee, Tapas; Opuwari, Mimonitu (Springer, 2021)Gamtoos Basin is an echelon sub-basin under the Outeniqua ofshore Basin of South Africa. It is a complex rift-type basin with both onshore and ofshore components and consists of relatively simple half-grabens bounded by ... -
Biomarkers, stable carbon isotope, and trace element distribution of source rocks in the Orange Basin, South Africa: implications for paleoenvironmental reconstruction, provenance, and tectonic setting
Yelwa, Nura A.; Mustapha, Khairul A.; Opuwari, Mimonitu; Aziz, Azharuddin A. (2021)Aptian to Campanian sediments from the Western ofshore to Central Orange Basin were studied by integrating molecular geochemistry, inorganic and isotopic studies to recognize their geochemical characteristics via the ...
