This was shortly followed by a series of workover and completion operations in Total’s Elgin/Franklin fields with the most extreme HPHT conditions ever encountered in the North Sea. Notably, it still remains in use there today.

Less curiouser
 In our last issue, we asked readers for their help with a puzzling result from a North Sea perforating operation (Curiouser and curiouser). In summary, the operator used a straight 1.86 s.g. /15.5 ppg cesium formate brine, rather than a formulated kill pill, and yet still only lost 14 bbl of clear fluid into the formation. We asked “why?”
