Martin at the bottom of the inclined trench, replacing the broken hatch on the borehole well-head. The photo is taken of the image on a video display in the drillers cabin that takes a video feed from a camera trained on the well-head. We normally use this display to monitor the safe entry of the drill into the borehole. Above Martin’s head hangs the drill, while to his left is a ventilation shaft that sucks away the drilling fluid fumes that otherwise accumulate at the bottom of the trench
