Shale Gas: Results of First Pilot Drilling 'Promising'

Algeria has successfully completed its first pilot drilling of shale gas in the Ahnet Basin (In Salah), which is ''very promising,'' Minister of Energy Youcef Yousfi said Saturday.

''We are witnessing a successful first exploration of shale gas in the Ahnet basin where we were able to produce extremely compact gas in impermeable rock,'' Yousfi told APS a press briefing after his inspection visit to the first pilot drilling of shale gas in Algeria.

He was accompanied by Minister of Water Resources Hocine Necib, and Minister of Town Planning and Environment Dalila Boudjemaa.

This first pilot well drilled by Sonatrach has confirmed the existence of substantial reserves of shale gas in the Ahnet basin, located in In Salah, 50 km of Tamanrasset, said Yousfi.

This well allows to consider moving forward in the possible exploitation of these unconventional gas resources, he stressed, noting that the studies in Ahnet basin through this first drilling have revealed the existence of a third perimeter containing shale gas, which spans 100,000 km2, he added.

Sonatrach expects in Ahnet two billion m3 per km2, i.e. total reserves of 200,000 billion m3 of gas for the entire basin. 10% of these reserves can be extracted, including 20,000 billion m3 of recoverable gas.

Yousfi dubbed ''these resources, very important and useful for the country, we cannot leave them unexploited.''

The drilling of AHT1 H2, the first pilot well of shale gas in Algeria, begun in August 2008 in the range of 1,800 meters vertical and 2,000 meters horizontal.
