Cape Town, South Africa — 12 September 2012 – The government of South Africa  has given a very conditional green light to the exploration of shale gas in the Karoo basin, according to minister of mineral resources Susan Shabangu, who says it will have to assess every step towards full-scale hydraulic fracturing for possible unacceptable outcomes.

Miningmx reports that Shabangu was presenting the findings of a task team commissioned in early 2011 to evaluate both the possible positive and negative effects of shale gas exploitation in the Karoo. The task team’s deliberations coincided with a ban on the exploration of shale gas which was lifted last week.

For now, Shabangu said applicants would be allowed to proceed with the initial stages of exploration, including geological field mapping and other data-gathering activities, until such time as an appropriate regulatory framework had been put in place. Actual fracking activities, essential during the later stages of exploration when determining the financial viability of a potential project, would for the time being remain prohibited.

Initial exploration would go a long way towards confirming whether the Karoo indeed held the estimated technically recoverable resource of 485 trillion cubic feet (Tcf) of gas, Shabangu said.

“It is impossible to quantify the resource accurately, other than to say that it is potentially very large,” read an executive summary of the task team’s report. “It is essential that additional, modern subsurface information be obtained through drilling or a geophysical survey to constrain these estimates.”

The report said that while exploration right holders conducted their so-called initial activities under the legal framework provided by the Mineral and Petroleum Resources Development Act (MPRDA), a new working committee would work on the establishment of appropriate regulations, controls and co-ordination systems  “’ a process expected to take between six to twelve months.

“Once all the preceding actions have been completed, government would authorise hydraulic fracturing under strict supervision of the monitoring committee,” read the report. “In the event of any unacceptable outcomes, the process may be halted.”

Among the report’s listed fears count the impact of shale gas mining on the environment, water use and air pollution.

The Departments of Mineral Resources and Science and Technology would also have to come up with a strategy on how shale gas mining and the recently awarded Square Kilometre Array Radio Telescope project could co-exist in the same environment.

Still, the task team found that shale gas exploitation would hold massive benefits for South Africa’s economy and reduce the country’s reliance on fossil fuels.

“Making a moderately optimistic assumption that ultimately 30 TcF will be produced…the gross sales value would be almost R1 trillion,” read the report, based on the assumption of a US$4 per thousand cubic feet of gas and an exchange rate of R8/$.

It said MossGas’s 1 TcF gas-to-liquids project was sufficient to provide around 5% of the national demand for liquid fuels and entailed 1,500 jobs.
