摘要:Te unconventional gas resources in the Lower Palaeozoicshale of Denmark were recently assessed by the United StatesGeological Survey (USGS; Gautier et al. 2013). Assumingunrestricted application of best practice current technology,recoverable gas resources of 0 to 130 × 109 Nm3 gas wereestimated onshore (mean = 67 × 109 Nm3 gas) and 0 to 228 ×109 Nm3 gas were estimated offshore (mean = 119 × 109 Nm3gas), i.e. a total estimated mean of 186 × 109 Nm3 gas (Nm3:normal cubic metre, unit used for natural gas at 0°C and101.325 kPa). Nearly all of this potential resource is assumedto be contained in the Cambro-Ordovician Alum Shale. Tewide range of estimates reflects the sparse data and the geological uncertainty inherent in the still untested play. Teestimated mean quantity of gas resource is comparable to thetotal volume of gas produced from the Danish part of theNorth Sea during 1972–2011 and twice the amount of theestimated remaining reserves of conventional gas in the Danish part of the North Sea.
