The coach of the first women’s hockey team of the University of the Free State is confident that they can do well in the upcoming Varsity hockey tournament.

The competition works on a gender-rotation system every year. This will be the fourth term of Varsity hockey for women. The Kovsie women has a good record. In 2013 they ended fourth, in 2015 they were second, and in 2017 fifth.

The Kovsies will be facing the University of Johannesburg (UJ) on Friday 3 May 2019. On Saturday, the Maties is lying in wait and the North-West University on Sunday.

“I am confident that we will be doing well. If each player plays her role very well, we should reach the semi-final stage. We have put in the hard work, with good progress. We have played three matches so far in 2019 and haven’t been on the losing side yet,” said Luke Makeleni, head coach.

In friendlies last month, the Kovsies drew to NWU (0-0), defeated UJ by 3-1, and had a good win (6-0) against the Johannesburg club, Shumbas.

“We have quite an experienced squad, with seven survivors from the previous Varsity hockey competition (in 2017), so they know what is expected,” Makeleni said. He is in his third year of coaching the women.

The Kovsies have several players with national experience. Simoné Gouws made her debut for the Proteas last year. Casey-Jean Botha, Shindré-Lee Simmons, Antonet Louw, and Lizanne Jacobs have all represented the South African U21 team. Botha is also in the Protea squad. 

■ The Kovsie team: Wiané Grobler, Chane Hartel, Mikayla Claassen, Anke Badenhorst, Casey-Jean Botha, Shindré-Lee Simmons, Esté van Schalkwyk, Nadia van Staden, Antonet Louw, Michelle Ngoetjane, Heraldine Olin, Lizanne Jacobs, Refilwe Ralikontsane, Mielanka van Schalkwyk, Nela Mbedu, Simoné Gouws, Frances Louw, Kia-Leigh Erasmus.

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.
