The influence of clay diagenesis on the petrophysical properties of sandstone reservoirs in the Pletmos Basin Offshore South Africa
(University of Western Cape, 2020)Pletmos Basin is a Mesozoic half graben located in the southern part of South Africa and has undergone numerous tectonic changes which involve alteration of structure and reworking of sediments. Clay diagenesis has become ... -
Influences of river flows on recruitment success of Fynbos riparian vegetation along selected high gradient streams in the Western Cape, South Africa
(University of the Western Cape, 2014)Riparian vegetation occurs in two distinct zones, the wet bank and the dry bank. Knowledge on how the flow regime influences the zonal structure of riparian vegetation is required to mitigate the adverse effects of water ... -
Institutional overlaps in water management in the Eerste River catchment
(University of the Western Cape, 2005)In this minithesis I have investigated overlapping mandates as a source of management failure in water management in South Africa in general and Eerste River Catchment in particular. I analysed major legislation which deals ... -
Integrated approach to solving reservoir problems and evaluations using sequence stratigraphy, geological structures and diagenesis in Orange Basin, South Africa
(University of the Western Cape, 2010)Sandstone and shale samples were selected within the systems tracts for laboratory analyses. The sidewall and core samples were subjected to petrographic thin section analysis, mineralogical analyses which include x-ray ... -
Integrated approach to solving reservoir problems and evaluations using Sequence Stratigraphy, Geological Structures and Diagenesis in Orange Basin, South Africa"
(University of the Western Cape, 2010)The use of integrated approach to evaluate reservoir rock quality and source rock potential is becoming increasingly important in petroleum geology. This approach was employed to unravel the reason for variable reservoir ... -
An integrated study of the early cretaceous (Valanginian) reservoir from the Gamtoos Basin, offshore South Africa with special reference to seismic cacies, formation evaluation and static reservoir modeling
(University of the Western Cape, 2019)Integrated approaches in the study of petroleum exploration are increasingly becoming significant in recent times and have yielded much better result as oil exploration is a combination of different related topics. The ... -
An integrated study of the early cretaceous (Valanginian) reservoir from the Gamtoos Basin, offshore South Africa with special reference to seismic facies, formation evaluation and static reservoir modeling
(University of the Western Cape, 2019)Integrated approaches in the study of petroleum exploration are increasingly becoming significant in recent times and have yielded much better result as oil exploration is a combination of different related topics. The ... -
Integrating 3D basin modelling concept to determine source rock maturation in the F-O Gas Field, Bredasdorp Basin (offshore South Africa)
(University of the Western Cape, 2015)The burial history, thermal maturity and petroleum generation history of the F-O Gas Field, Bredasdorp Basin have been studied using 3D basin and petroleum systems modelling approach. The investigated sedimentary basin for ... -
Integration of petrographic and petrophysical logs analyses to characterize and assess reservoir quality of the lower cretaceous sediments in the Orange basin, offshore south africa
(University of the Western Cape, 2017)Commercial hydrocarbon production relies on porosity and permeability that defines the storage capacity and flow capacity of the resevoir. To assess these parameters, petrographic and petrophysical log analyses has been ... -
Investigating associations between fluvial style and the characteristics and distribution of geomorphic units in non-perennial rivers
(University of the Western Cape, 2019)Although non-perennial rivers are the most dominant river type in arid and semi-arid areas, far outnumbering perennial rivers, recent reviews have shown that the knowledge base supporting non-perennial river research is ... -
Investigating channel change in relation to landuse change in the Klein Berg River, Tulbagh
(University of the Western Cape, 2005)The Klein Berg River catchment is intensely cultivated with orchards, vineyards and wheat, while also ensuring a water supply to the main urban center, Tulbagh, and the two conservation areas (Waterval and Groot Winterhoek). ... -
Investigating groundwater governance arrangements for unconventional gas exploration and production in main Karoo Basin, South Africa
(University of the Western Cape, 2016)South Africa relies on coal and imported crude oil for most of its energy. The possible production of shale gas in the main Karoo Basin of South Africa provides a potential opportunity to diversify the primary energy mix. ... -
Investigating hydrogeochemical processes of groundwater, Heuningnes Catchment, South Africa
(University of the Western Cape, 2020)This study was conducted to investigate hydrogeochemical processes controlling the evolution of groundwater chemistry and their influence on water quality in the Heuningnes Catchment. The role or influence of hydrogeochemical ... -
Investigating subsurface heterogeneities and its impact on the variation in interval velocities : implications to velocity modelling in the Bredasdorp basin
(University of the Western Cape, 2015)Velocity modelling forms an integral part of the seismic interpretation process initially completed in two-way time. In order for a representative depth conversion, it is obligatory to construct a velocity model that serves ... -
Investigating the effects of nutrients and chlorophyll concentrations on the water quality of the Nuwejaars River, Cape Agulhas, Western Cape
(University of Western Cape, 2021)The Nuwejaars River flows into the largest natural freshwater lake in South Africa, Soetendalsvlei, which relies on and interacts with the Nuwejaars River. Therefore, the water quality of the Nuwejaars River plays a role ... -
Investigating the impact of effluent from wastewater treatment works on river water quality, Baths River, Caledon, Western Cape, South Africa
(University of Western Cape, 2021)South Africa is facing a problem of many municipal waste water treatment works (WWTW) not working efficiently. The environmental impacts of poorly treated effluents on receiving water bodies have required special attention ... -
Investigating the natural groundwater recharge and discharge processes of the Saldanha Bay aquifer systems along the West Coast of South Africa
(University of the Western Cape, 2022)Saldanha Bay Local Municipality is partially dependent on groundwater as part of its bulk water supply as surface water resources in the area are extremely limited and fully allocated. Due to this, there is lots of ... -
Investigating the role of groundwater - surface water connectivity in supporting non-perennial river systems, Sandveld, Western Cape, South Africa
(University of the Western Cape, 2021)Non-perennial rivers are characterised by a discontinuous and variable hydrological flow regime which may retreat to form isolated pools along the watercourse during prolonged dry periods. The resulting spatio-temporal ... -
