The Kovsie Annerie Dercksen is one of South Africa’s most promising youngsters and climbing the cricketing ladder.

She enjoyed every second of playing with some of her heroes and believes the exposure to international cricket will help her become a better player.

Annerie Dercksen is one of South Africa’s most promising youngsters and climbing the cricketing ladder.

Star from Beaufort West

This second-year Education student from the University of the Free State (UFS), who dreams of playing for the Momentum Proteas, represented the South African Emerging Women’s team three times in 2021.

The star from Beaufort West toured with the side to Bangladesh and also played against Zimbabwe and Thailand in One Day and T20 matches.

According to Dercksen, it is an incredible honour and privilege to be a part of a side.

She soaked up the experience and says everyone was willing to share their knowledge.

“I would have to say, sharing the field with some of my heroes and getting to work with some of the best coaches in the country are some of the highlights.”

She says each tour brought its own challenges and this helped her grow in the way she views and approaches the game.

“In Bangladesh we played against a well-established team in foreign conditions while facing a lot of spinners in spin friendly conditions. Personally, it was quite a challenge and I had to come back and work on some options, especially against spin.”

“Each tour brought its own challenges and this helped me grow in the way I view and approach the game.” - Annerie Dercksen

Coming through the ranks

The all-rounder has come through the ranks. She represented South-Western Districts at school level, played for the South African U19 side and is currently representing the Free State.

But Dercksen didn’t always dream cricket, especially not when playing ‘backyard’ cricket with her brother on the farm.

She didn’t even play for a team at school. “Until a boy from our primary school’s team got sick before a game. A teacher came to class and asked, ‘who can play cricket’, and I put up my hand.”

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.
