We're at about 350 meters beneath the lake bed. Still having problems with the drilling mud. The drillers have cut back to four cups per tank (they used about 10-16 cups in Lake Van!). Even at this amount, it is turning hard quickly. Ein Gedi Emergency Rescue Team conducted a drill yesterday and tested their equipment. All is good. We lost our laptop on the drilling rig when coffee was accidentally spilled on it. Another setback tonight - near the end of the day shift, the H2S monitor went off-scale. Operations were suspended while we look to bring in an expert for advice.
