Hi Mixster. Thanks for your helpful posting. Your information about three rather than just two potential reservoir targets at WN (the Brotherton, Kirkham Abbey and Cadeby formations) was very interesting as I hadn't heard about the Brotherton before. I've tried to find out a bit more since. Apparently Brotherton is the latest name for the much better known Upper Magnesian Limestone, and it's present over much of East and NE England. The Cadeby is a new name for the Lower Magnesian Limestone and it's also fairly widespread. I don't know what the Kirkham Abbey, where the oil and gas are located, was previously called, but it sits in between the two other limestones. From some geology maps published in the 1980’s I was able to discover that the KA formation is well developed in the area around, and to the north and south of WN. What puzzles me, though, is that the Cadeby is much thicker to the west, and the Brotherton is much thicker to the east, apparently under the Southern North Sea. The Rathlin people presumably know what they are doing but, if the old maps are right, they could get a bit of a surprise. Only time will tell if the WN B-1 well is located in a good place to find oil in the Cadeby reef, if that’s what it really is, but I sincerely hope the KA formation will be good as it was in the A-1 and A-2 wells. So, roll on B-1 spud, I say!
