6Tight natural <strong>gas</strong>• Permeability less than 0.1md(1*10 -16 m 2 )• Porosity approx. 5-15%• Limestone or sandstoneformations• Not readily extractable. We mustput more effort into theextraction process than forconventional <strong>gas</strong> <strong>reservoir</strong>s; likefracturing, acidizing etc.
