Note that modelling using hyperbolic decline rates and production rates from USA suggests that to it would take at least 10 years to get to a point where 3,000 wells would generate about 25% of UK gas demand and if they stopped drilling at 3,000 wells it would only be for one year.
By this stage all of those wells would have provided cumulatively just over 1 year's worth of UK gas demand, after which if they stopped siting more pads production would drop off very steeply. After a further 10 years those wells would only be providing about 0.25 tcf a year.
The hamster wheel of drilling more and ore wells has to keep turning. More wells have to be drilled and more pads sited. Cuadrilla are not in this game to to extract less than 10 tcf of gas over 30 years - Corin Taylor claims they want to get 10% of 200 tcf which would be 20tcf and a lot more wells than 3,000. Using IoD figures suggested by Taylor they's need 6250 well for that.
In 2016 Professor Alpin stated that extracting the gas he believed to be available in the entire Bowland Shale "would entail drilling somewhere between 15,000 to 20,000 wells on some 2,000 to 3,000 well pads".
75 pads? I don't THINK so.
