13. A geological study of the lower Ecca Group north of Grahamstown, South-East Karoo Basin, South Africa

Ms Shereen Slamang (Nelson Mandela Metropolitan University)

01/10/2014, 09:25

Oral and Poster Presentation

The area of study lies in the Eastern Cape, approximately 20km north of Grahamstown, in the direction of Fort Beaufort. The main rock outcrops are along the Ecca Pass and approximately 10km east of the pass, along the Committees Drift Road. The area was chosen as it incorporates an exceptionally well exposed outcrop portraying all the formations of the lower Ecca Group of the SE Karoo Basin in...

55. Borehole stratigraphy, organic geochemistry and petrography of Permo-Carboniferous Lower Ecca black shales: Implications for their shale gas potential

Ms Naledi Chere (AEON - NMMU)

01/10/2014, 09:40

Oral and Poster Presentation

In the Main Karoo Basin, Permo-Carboniferous black shales of the Lower Ecca Group, especially the Prince Albert and Whitehill Formations, are considered to be a potential source of shale gas. Core samples of shale were collected from eight boreholes predominantly drilled in the 1960’s, and stored at the Council for Geosciences’ core library in Pretoria. The carbonaceous black shale of the...

7. Characteristics of Permian gas-shales in the lower Karoo Supergroup nearJansenville in the Eastern Cape, South Africa

Ms Claire Geel (NMMU MSc)

01/10/2014, 09:55

Oral and Poster Presentation

This is a study on the geochemical and petro-physical properties of shales from the Prince Albert, Whitehill and Collingham Formations of the Lower Karoo Supergroup, near Jansenville in the Eastern Cape. Results are based on two boreholes sited on a southerly dipping limb of a shallowly plunging syncline. Lithological, sedimentological, structural, geochemical and petro-physical analyses...

52. A structural and geochemical analysis of the Karoo sedimentary rocks along dolerite dyke and sill contacts with implications on shale gas potential

Ms Vhuhwavhohau Nengovhela (Nelson Mandela Metropolitan University)

01/10/2014, 10:10

Oral and Poster Presentation

The main Karoo basin sedimentary sequence covers an approximate area of 700 000km2, and attains a thickness of more than 5Km. The emplacement of the Karoo Large Igneous Province (LIP) through dolerite dykes and sills, and lava flows (ca 183Ma) led to extensive devolitilization, metasomatism, and out-gassing of approximately 2000Gt of carbon dioxide and methane into the atmosphere. The effects...

72. FRACTURE SYSTEMS in the Karoo basin: Differentiating brittle structures related to DYKE AND SILL EMPLACEMENT from those related to Tectonics

Mr Thomas Muedi (AEON - NMMU)

01/10/2014, 10:20

Oral and Poster Presentation

Poster (All students)

The Karoo Basin is an area intruded by dolerite sills and dykes. It is also speculated that those dolerite rocks may have intruded through pre-existing fractures. Fractures are well known as joints by geologists. Fractures are commonly formed when the stress exceed the rock strength and they acts as pathways to the hydrocarbon migration, water and other fluids during Karoo dolerite...

71. Baseline Geochemical study of the natural gas and Karoo formation waters prior to Fracking

Ms Moipone Precious Mokoena (AEON - NMMU)

01/10/2014, 11:10

Oral and Poster Presentation

Poster (All students)

The potential for shale gas extraction in the South African Karoo has been one of the most controversial issues because of the unknown extent of socio-economic and environmental impacts. Although we can learn about the pros and cons of shale gas development from the US and other countries, South Africa’s unique geology and semi-arid climate makes the extraction of gas more complex. South...

57. Baseline Groundwater Hydrochemistry and Aquifer Connectivity of the Eastern Cape Karoo Prior to the Proposed Hydraulic Fracturing of Shale Gas

Ms Moipone Precious (obo Divan Stroebel) Mokoena (AEON - NMMU)

01/10/2014, 11:10

Poster Presentation

The anticipated exploration and exploitation of Karoo Shale Gas has raised considerable debate about the benefits and risks associated with this process for both the Karoo, and the country as a whole. Focus has been placed on the potential impact of hydraulic fracturing on ecological, environmental and especially its scarce water resources. The Karoo region is highly dependent on groundwater...

34. Diversity of invertebrates in temporary water bodies of the Eastern Cape Karoo region earmarked for shale gas exploration

Mrs Annah Mabidi (AEON-ESSRI)

01/10/2014, 11:20

Oral and Poster Presentation

Temporary freshwater bodies (endorheic pans) are facing a variety of disturbances including hydrological modifications, filling up with substrate and invasion by vegetation. These impacts have collectively resulted in loss of ecological value and habitat for invertebrate communities which utilise these transient ecosystems. Historically, the water bodies of the Karoo semiarid region have been...

8. The vegetation of the proposed Karoo fracking sites and ecophysiological responses of plants to fracking chemicals

Mrs Annah (obo Kristen Ellis) Mabidi (AEON-ESSRI)

01/10/2014, 11:20

Poster Presentation

Hydraulic fracturing or fracking is an extraction technique that is used to extract gas from rocks of low permeability. A number of companies have been either applied for, or been granted Exploration Rights for fracking in the Karoo. Shell’s application area is in the magisterial districts of Aberdeen, Beaufort-West, Carnarvon, Graaff-Reinet, Middelburg, Murraysburg, Noupoort, Richmond and...

58. Geophysical processing, integration, and visualisation of multi-parameter survey data over parts of the Eastern Cape

Mr Martin Bentley (AEON - NMMU)

01/10/2014, 11:30

Oral and Poster Presentation

The Eastern Cape, South Africa, suffers from a general lack of high-resolution geophysical data. This is largely due to a historical lack of interest in subsurface exploration in the area from an economic viewpoint which led to a lack of funding being available to carry out such surveys. Until relatively recently, studies have been largely limited to small areas for particular research...

70. 3-D Karoo basin reconstruction from ambient passive seismic noise

Mr Lucian Bezuidenhout (Nelson Mandela Metropolitan University)

01/10/2014, 11:40

Oral and Poster Presentation

Poster (All students)

The increased interest in the potential shale gas extraction within the Karoo basin is raising concerns regarding the potential impact it may have on this fragile environment. In order to be in the possible position to moderate any negative effects associated with possible hydraulic fracturing, a scientifically thorough base-line of this region will need to be obtained. Since our current...

53. Preliminary results from a field reconnaissance for shale gas in the Karoo of Tanzania

Mr Bastien LINOL (AEON - NMMU) , Mr Taufeeq Dhansay (AEON - NMMU)

01/10/2014, 12:00

Oral and Poster Presentation

The Karoo is a Gondwanan basin type sequence that extends across South America, south-central Africa, Madagascar, India and Antarctica. It is currently being investigated in South Africa, with special interest for black shale and its potential toward energy and socio-economic development. Curiously, there was no mention of shale gas at the 25th Colloquium of Africa Geology, in Dar Es Salam,...

56. Shale Gas in South Africa: Contextualizing the Socio-Economic and Political Implications

Mr Barry Morkel (AEON - Karoo Shale Gas Research Programme)

01/10/2014, 12:10

Oral and Poster Presentation

Poster (All students)

The confluence of three key technological and social-economic drivers have given rise to the advent of the new ‘Golden Age of Gas’ , as articulated in the new global discourse of unconventional oil and gas, and in particular what has been described as the ‘Shale Gas Revolution’ . These drivers include the technological advances in multi-directional and horizontal drilling and hydraulic...
