Agreed! As can be seen in the graphs, each of the wells have been fracked in different depths/sections as part of the calibration testing. Lessons learnt from each well will allow them to properly target the higher yielding sections with the best fracking/water removing methods. Hence why they are going back to Well 4 for further testing. They will utilise the methods from wells 5 & 6 to hopefully improve the water removal and gain better flows.
