Talk:Groningen gas field

• "The discovery of the huge Groningen gas field in 1959 caused a crisis in the coal-mining industry. In 1965 the government decided to close down the mines."^[1]
• "28 clusters with 283 producing wells and 16 observation wells are spread over the field"^[2]
• "Until recently, the giant Groningen field (estimated ultimate recovery 2700 × 109 m3) in the north of the country acted as a ‘swing producer’, because it could meet the so-called ‘swing’, i.e. the seasonal and daily or hourly fluctuations in demand"^[3]
• "formed in the carboniferous period (365-290 million yearsago). Subsequently, it has migrated upwards to the porous snadstones in the Rotliegend layer from Permian Period (390-250 million years ago)..... The gas reservoirs are sealed by Ten Boer claystone layer and the thick Zechstein salt layer." "900km2 2700billion m3 recoverable volume"^[4]
• "Suddenly pennies dropped in the minds of many geologist and many oil companies and the posibility of extension into the Southern North Sea of the Groningen reservoir providence became reasonable premise"^[5]
• ".. belonged to one major structure. This was confirmed when the Ten Boer well was deepened in 1963 to find gas water contact at 2950m."^[6]
• "The reservoir, 300-700 ft thick, consists of fluviatile and eolian sandstone and conglomerate of the Rotliegendes Formation (Lower Permian)."^[7]

This article claims that the gas field is the tenth largest gas field in the world, but on List of natural gas fields it is listed as the ninth largest. Targaryen^{speak or forever remain silent} 21:21, 16 October 2013 (UTC)

The section about size makes it sound like the reserves are the amount available or recoverable as of now, and not historical size or the originally available amount. It should be mention that, according to sources that I've read, that the originally recoverable reserves were up to 2.8 trillion m3, but that there is, as of today, only about 0.450 trillion m3 left (450 bn m3). 2A01:799:1B9B:C300:ADB7:7BB2:E4C4:DE5F (talk) 01:06, 13 March 2023 (UTC)
