sum24Hr: Drilled 8 1/2" hole from 2883 m to 2915 m MD. Pumped and spotted a third 5 m3 LCM pill at TD due to heavy losses of 36 m3/hr. POOH to 2775 m (top of LCM pill). Staged up pump rate to 1800 lpm. Shut off pumps and RIH to TD. Staged up flow rate to 1800 lpm to be able to continue drilling. Drilled 8 1/2" hole from 2915 m to 2932 m MD.
