It was certainly a very spectacular sunrise yesterday 13th December and worth its position as a featured image on this post. But it has to be admitted that this is a rather contrived headline to lead us into the subject of coring of the Tinker lane borehole. At the Community Liaison Group meeting last evening, the Nottinghamshire County Council representative sprung a question, “How Deep?”and the IGas representative was placed on the spot. “1,400 metres” came a reflex reply. So now we know, we are down at the expected level of the Millstone Grit, IGas’ secondary target and where we expect the drillers to take a core sample, maybe several cores. From what we could make of the drilling progress today, over the fence, they were drilling very slowly indeed. It appears therefore that they might already be coring. So this week we have had a couple of cor(e) blimey moments, a marvellous sunrise and an official confirmation that the bottom of the hole is currently at 1.4 kilometres.
We expect the final depth to be around 1,800 metres or to the bottom of the Top Bowland Shale whichever is deepest.
