Core Recovery, Handling and Packing
A pre-job safety meeting shall be held before pulling the core barrel through the rotary table to ensure that the Drilling and Service Contractors’ personnel understand the job and potential hazards (eg., trapped pressures and catcher failure).
Recovery - H2S
If there is any possibility of the core containing H2S, only the Drilling Supervisor, Driller, Coring Contractor and the minimum necessary number of floor men shall be present when pulling the core barrel through the rotary table. All personnel shall wear breathing apparatus until it is confirmed that H2S is absent.
