New #KovsieCyberSta duo ready to roll

The search for the 2019/2020 #KovsieCyberSta team has been an exciting one, with Anderson Mosia and Olebogeng Tlhong coming out tops to beat the competition.
Anderson, a second-year BA Languages student, didn’t let last year’s failure deter his efforts to enter again this year.

“I am hoping to achieve a lot of things. My milestone would be to raise the bar high for the next stars; I've got a lot in store,” he says.

He says he is passionate about spreading love, and he will use this new platform to express himself.

It has been first-time charm for first-year LLB student, Olebogeng. She says as soon as she saw the competition was open, she knew it was something that would fit her persona.

“I am hoping to not only grow as an individual, but to leave my mark. The question that I asked myself before stepping into this role, was –what’s going to be different because you stepped in? I aspire to document and present events in the best way that I know, while being open to learning and, through my knowledge, inspire and teach others.”

The 19-year-old says she will use her passion for serving to express herself best over the next 12 months.

“I believe that it is my duty to use the knowledge I have acquired/am to acquire in order to make somebody else’s life better. So essentially, I am a servant leader; I believe that there is enough room for everybody to succeed,” she adds.

As #KovsieCyberStas, the duo will cover events on and around campus, while filming and presenting short video clips to give fellow Kovsies some insight into these events across the UFS’s digital platforms.

Fracking in the Karoo has advantages and disadvantages

Fracking for shale gas in the Karoo was laid bare during a public lecture by Dr Danie Vermeulen, Director of the Institute for Groundwater Studies (IGS). He shared facts, figures and research with his audience. No “yes” or “no” vote was cast. The audience was left to decide for itself.

The exploitation of shale gas in the pristine Karoo has probably been one of the most debated issues in South Africa since 2011.

Dr Vermeulen’s lecture, “The shale gas story in the Karoo: both sides of the coin”, was the first in a series presented by the Faculty of Natural and Agricultural Science under the theme “Sustainability”. Dr Vermeulen is a trained geo-hydrologist and geologist. He has been involved in fracking in South Africa since the debate started. He went on a study tour to the USA in 2011 to learn more about fracking and he visited the USA to further his investigation in May 2012.

Some of the information he shared, includes:

- It is estimated that South Africa has the fifth-largest shale-gas reserves in the world, following on China, the USA, Argentina and Mexico.
- Flow-back water is stored in sealed tanks and not in flow-back dams.
- Fracturing will not contaminate the water in an area, as the drilling of the wells will go far deeper than the groundwater aquifers. Every well has four steel casings – one within the other – with the gaps between them sealed with cement.
- More than a million hydraulic fracturing simulations took place in the USA without compromising fresh groundwater. The surface activities can cause problems because that is where man-made and managerial operations could cause pollution.
- Water use for shale-gas exploration is lower than for other kinds of energy, but the fact that the Karoo is an arid region makes the use of groundwater a sensitive issue. Dr Vermeulen highlighted this aspect as his major concern regarding shale-gas exploration.
- The cost to develop is a quarter of the cost for an oil well in the Gulf of Mexico.
- Dolerite intrusions in the Karoo are an unresearched concern. Dolerite is unique to the South African situation. Dolerite intrusion temperatures exceed 900 °C.

He also addressed the shale-gas footprint, well decommissioning and site reclamation, radio activity in the shale and the low possibility of seismic events.

Dr Vermeulen said South Africa is a net importer of energy. About 90% of its power supply is coal-based. For continued economic growth, South Africa needs a stable energy supply. It is also forecast that energy demand in South Africa is growing faster than the average global demand.

Unknowns to be addressed in research and exploration are the gas reserves and gas needs of South Africa. Do we have enough water? What will be the visual and social impact? Who must do the exploration?

“Only exploration will give us these answers,” Dr Vermeulen said.
