I'm going to take a stab in the dark here. I reckon it could be that the rig is shifting during drilling due to the sands it sits on. The solution will be to exit the hole and plug it, dismantle the rig, move it to one side then build a stable platform. Move rig back in place then restart drilling. Time frame 1 month cost £1.5 - 2 mill.
