UK’s IGAS says its licenses hold as much as 172.3 trillion cubic feet of shale gas

IGas, one of the leading producers of onshore hydrocarbons in the UK, has upped its estimates of Gas Initially In Place (GIIP) associated with the shales under its license in the north west of the UK, including the Bowland Shale, as ranging from a low of 15.1 trillion cubic feet (Tcf); a most likely volume of 102.0 Tcf; and a high of up to 172.3 Tcf. The company had previously estimated some 9 Tcf GIIP.

Actual production volumes would be smaller.

IGas constructed constructed a geological model utilizing 330 km of reprocessed seismic lines, subsurface data (including cores, logs) from around 20 offset wells and geological data from IGas’s well at Ince Marshes. This data was analysed to give the new estimates of the reservoir characteristics of the shale formations and the thickness of the shale.

The new estimates cover an area of 300 square miles giving an average mid-case in-place volume of around 340 Bcf/ square mile with a range of 93 Bcf/square mile to 677 Bcf/square mile across the IGas North West acreage.

The planned drilling program, commencing later this year, will further refine these estimates and advance our understanding of this shale basin. We will in due course carry out further analysis and reinterpretation of existing seismic and subsurface data to evaluate the potentially prospective Shale resources in the East Midlands and Weald Basin licence areas.

To put those figures in context, and using metric not PIA cu feet, that is around 3 trillion cu metres.
UK annual consumption is ~100bn cu metres, so that is around 30 years consumption.

Of course the figures given are for the resource base, and considerably less would be extracted, but although likely this is the richest UK shale gas field there are others, with unknown resources.

This will be good for England's economic future. SG extracted in many other EU countries would be more than welcomed and would help to pull out of the current economic depressions?
