Samakinde, Chris Adesola (2013)Clay diagenesis phenomenon and their effects on some petrophysical properties of lower cretaceous silliciclastic sandstones, offshore Orange basin have been established. Previous studies on Orange basin revealed that ... -
Basin Evaluation of Turonian Deposits in the Lower Congo Basin using outcrops, cores, well-logs and seismic
Kibini, Ntouadi (University of the Western Cape, 2017)This manuscript presents a review of the Turonian series of the Congolese Coastal Basin using outcrop, core, well-logs and seismic data in order to provide a comprehensive model for the series and increase the oil recovery. ... -
Burial history and source rocks characteristics of the montney formation, Alberta basin, Canada
Dwane, Zandile (University of the Western Cape, 2016)More than 300 samples from the Montney Formations in the Alberta basin, offshore, Canada have been analysed with locations in various parts of the Alberta basin. These samples were mainly analyzed from two wells (well M28 ... -
Characterization of potential source rocks of the Prince Albert, Whitehill and Collingham formations in the Laingsburg sub-basin, South Africa
Ferreira, Janine Connie (University of the Western Cape, 2014)The present research deals with the characterization of the Lower Ecca Group in terms of sedimentology, mineralogy and organic geochemistry. A field study was conducted in order to characterize the sedimentology and thereby ... -
Comprehensive fluid saturation study for the Fula North field Muglad Basin, Sudan
Altayeb, Abdalmajid I. H. (University of the Western Cape, 2016)This study has been conducted to accurately determine fluid saturation within Fula sub-basin reservoirs which is located at the Southern part of the Republic of Sudan. The area is regarded as Shaly Sand Reservoirs. Four ... -
Determination of total organic carbon content using Passey’s ΔLogR method in coals of the Central Kalahari Karoo Basin, Botswana.
Mabitje, Mamphedi Sylvia (University of the Western Cape, 2016)The Kalahari Karoo Basin is one of several basins in southern Africa filled with Late Carboniferous to Jurassic sediments that are primary targets for Permian aged coal. In order to determine the Coalbed Methane (CBM) ... -
The effects of minerals on reservoir properties in block 3A and 2C, within the orange basin, South Africa.
Salie, Sadiya (University of the Western Cape, 2018)The reservoir quality of the Orange Basin, offshore South Africa is known to be immensely impaired by the presence of authigenic minerals. The collective effects of burial, bioturbation, compaction and chemical reactions ... -
