What happened in Reservoir section:
Reached TD without signifigent problems. Sampled acc. To plan.
Some pressure point samples unsuccessful due to “no seal”.
Sampling during “pump and pull” OOH was performed better than enticipated. Stood stationary for 7 hrs – had 26 kNm brakeover torque, free rot. Trq. 15 kNm.
Mud properties where good, holecleaning and weight readings followed roadmap.
Diciplined use of water – avoid water in OBM. When washing screens in shaker – route cuttings to skip during washing, than route back to ISO afterwards.
Very conventional parametres set in NOVOS for drilling. Not chasing micro KPI’s, but keeping focus on standing the whole distance.
Communication before and during drilling between all parties.
Having Teams-meeting with relevant & live info for all to see, keeps everyone focused and engaged.
