Out with the dog yesterday in Basingstoke area, there is a Rig up and working at the Humbly grove site which produces from the Great Oclite and Rhaetic layers. They do have Kimmeridge layers there but dont know were to find out what they are drilling into this time.
If Angus and Ukog are test the same layer at the same time they should be able to see the draw on the field from each other's wells if they are connected.
If that lorry had any Haz onboard it would have had to have Haz plates front back and the sides. This lorry had no plates. Best guess water for fire fighting.
