At the drill site a winter storm has been raging.

After the gyro-run yesterday morning drilling the cement (sliding) in an attempt to side-track commenced 06:15 at 1835 m depth. WOB was kept low, around 1 tonne, and ROP’s were kept at 0.5 m/hr to try to ensure a successful side-track. Circulation losses were variable but generally around 10 l/s when measured on the pumps. Last night ROP’s increased markedly although WOB was kept low. This occurred at ~1846 m depth, shortly after midnight. After reaching ~1849 m depth there appeared to be little or no resistance left in the cement plug and we were clearly “back” in the hole again.
