Khanyisa Chawane, a Protea player, should be one of the stars for the Free State Crinums in the Telkom Netball League. She was the Player of the League in 2018.

Having to play 11 matches in so many days before the knockout stage will be a daunting task, but their fitness levels are up to standard, says the coach of the Free State netball team. Burta de Kock of KovsieSport will again guide the Free State Crinums in the Telkom Netball League, which will be taking place between 14 and 27 October in Bloemfontein.

All but one of the 12 members of the team are studying at the University of the Free State (UFS).

“Planning will be of the utmost importance to manage the load on the players. We also have four players (Rolene Streutker, Chanel Vrey, Boitumelo Mahloko, and Refiloe Nketsa) who will participate in the South African U21 team that will play five invitational matches during the competition,” said De Kock.

In previous years, the competition took place over four to six weeks, but now it had to be fitted into two weeks due to COVID-19.

“So, it will be a tall order to play so many matches, but an exciting challenge. I believe the hard work the players had put in during the lockdown period will bear fruit. They were exceptional and very determined to stay in shape.”

The Crinums won the first three years of the competition, but couldn’t reach the final in the following three years. Apart from the 11 Kovsies in the Crinums team, there are 9 current or former UFS students in other teams participating in the league. 

They are Zandré Smit, Bianca Pienaar, Dané Klopper, Arné Fourie, Bethenie du Raan (all Northern Cape Diamonds), Maryke Coetzee, Danelle van der Heever (both Mpumalanga Sunbirds), Rieze Straeuli (Western Cape Tornados), and Alicia Puren (KZN Kingdom Stars).

The Crinums team: Boitumelo Mahloko, Ané Retief, Jana Scholtz, Khanyisa Chawane, Lefébre Rademan (captain), Sikholiwe Mdletshe, Claudia van den Berg, Bianca de Wee, Rolene Streutker, Chanel Vrey, Lerato Chabwe, and Refiloe Nketsa.

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.
