On Friday, IFP spokesperson on Energy, Honourable JA Esterhuizen, addressed the National Assembly of Parliament on local gas extraction and the long-term impact it will have on the South African economy.

The MP said that affordable energy is a key driver for economic development; however, he noted that “shale gas can be cheap energy or very expensive and in some circumstances, even disastrous if one factors in the very real possibility of environmental damage through fracking operations!”

Gas options

Esterhuizen explained: "What makes drilling in a shale formation unique is the necessity to drill horizontally, vertical drilling continues to a depth of approximately 1.5 – 3km then curved to become horizontal, lined with a steel casing and cement lining."

He further noted that shale gas wells are short life wells due to the fast depletion of the gas reservoir, which occurs because of the very fast flow rates of gas. Therefore, gas companies have to constantly ‘frack’ more wells in order to cover expenses.

"Fracking costs about R98 million ($7 million) per well, and much more considering the scarcity of water in this country. It takes approximately 19 million litres of water to frack a well, and up to 5 times that to keep their production revenues up in additional wells together with the cost of the long list of chemicals that are required for the process.

"Currently there is no real control through regulatory frameworks, which make it mandatory for contractors drilling the wells to disclose their chemicals and that’s the first ‘red flag’ and potential for contamination, as a failure of the well hole casing would allow for a release of those chemicals into our drinking water."

This and the huge amounts of money involved, given this government’s high integrity levels could only lead to drilling contractors taking short cuts, putting anything down the well hole without a permit or disclosure.

Drilling equals high costs

"In the course of the initial production of the well only 15 – 48 % of the 19 million litres of contaminated fracturing fluid is recovered and disposed of as it is too expensive to recycle for other fracturing operations. And when these companies say 'dispose of'' they mean pumping into a disposal well, back into the earth, thus continuing with the contamination of our groundwater supply," The MP said.

"We have a climate that lends itself to solar and wind clean energy generation, yet we stubbornly continue along the fossil fuel path. South Africa committed itself recently at the United Nations Framework Convention on Climate Change (UNFCCC) COP21 to phase out its reliance on fossil fuels, why then this contradictory position by allowing fracking?

"The IFP calls for far greater investment into renewable, clean energy sources and in no uncertain way opposes all calls to allow the conducting fracking in South Africa," he added.

  1. Esterhuizen does not know what he is talking about. Fracced wells do not rapidly deplete, the flow falls off as the supercharge dissipates; the frac chemicals cannot get into freshwater aquifer due to casing failure, as at no time are they in contact with the inside off the casing; His “up to 5 times” claim is incomprehensible; the existence of ‘disposal wells’ is a matter of policy – they are not permitted in some places.
