Opening Hole. Cleaning out shoe track. Working stuck pipe. The application of tools, equipment and techniques for milling. Start: Once the decision has been taken to commence a milling operation, or when it is evident that milling needs to take place. This operation can at times start with a trip out of the hole. End: When resuming operations as carried out prior to the start of the milling operationa at the same depth. A dedicated clean out trip prior to commencing drilling operations would still be considered part of this operation. Drilling to enlarging the diameter of the borehole.

All activities related to a plug back or cement plug. Starts: in most of the cases with rigging up to make up a cement stinger, or pulling out of hole to set a cement plug in case of losses. Ends: with the cement plug, where required tagged and tested and the cement stinger laid down. In case where a cement plug has been set to cure losses, the operation finishes once drilling depth has been reached prior to pulling out to cure losses.



The application of tools, equipment and techniques for the removal of junk, debris or fish from a wellbore. Starts: Once the decision has been taken to commence a fishing operation, or when it is evident that there is a fish in the hole. This phase can at times start with a trip out of the hole. Ends: When resuming operations as carried out prior to the start of the fishing operation at the same depth. A dedicated clean out trip prior to commencing drilling operations would typically still be part of this operation.

Operations applying technology focused on maintaining pressure on open formations, to prevent or direct the flow of formation fluids into the wellbore. Starts: With the first indication of a well control event, often with the start of a positive flow check or when the well is being closed in if no flow check has taken place. Ends: When resuming operations as carried out prior to the start of the well control phase at the same depth.

All operations to perforate the well from rig up to the completion of the rig down, including the time taken for unsuccessful perforating runs. This includes perforating prior to running sand screens either tubing conveyed or wireline, through tubing perforating with the completion installed, and the making up of TCP guns when running in hole with the completion. Start: Rigging up to perforate. End: when rigging down after all perforating runs have been completed. All operations to perforate the well on drill pipe, from rig up to the completion of the rig down, including the time taken for unsuccessful perforating runs. Start: Rigging up to perforate. End: when rigging down after all perforating runs have been completed.

Operations on the assembly of valves, spools, and fittings used for an oil well, gas well, water injection well, water disposal well, gas injection well, condensate well and other types of wells. The primary function of a tree is to control the flow into or out of the well, usually oil or gas. Start: Tubing hanger, barriers and completion have all been run and satisfactorily tested. For many wells this will be when starting to nipple down BOP. End: Tree installed and satisfactorily pressure tested and plugs removed.
