The following is being distributed at the request of the Canada-Newfoundland Offshore Petroleum Board:
Weekly Public Status Report
BOP/BOP Stack: Blowout preventers/blowout preventer stack - an assembly of heavy-duty valves attached to the wellhead to control well pressure and prevent a blowout.
Casing: Steel pipe set in a well to prevent the hole from sloughing or caving and to enable formations to be isolated (there may be several strings of casing in a well, one inside the other).
Cementing: Pumping a liquid slurry of cement, water and other additives behind a string of casing to isolate formations.
Completion/Completed::The activity necessary to prepare a well for the production of oil or gas or the injection of water or gas into the reservoir.
Fish: An object lost (or stuck) in the wellbore obstructing operations.
Fishing: Operations to recover fish.
Injecting: Injecting water or gas into the resevoir for the purpose of maintaining resevoir pressure, maximizing oil recovery and conserving resources.
Liner: A length of casing suspended from the base of a previously installed casing string (a liner does not extend back to the surface of the well).
Logging: Acquisition of downhole data using tools run in the well, usually on wireline.
Perforate/Perforating: Piercing the casing and cement using shaped explosive charges to provide a flow path for formation fluids
Producing/Production: Flowing oil and/or gas from a well to the production systems.
Production tree: An arrangement of heavy duty valves and fittings installed on the wellhead to control flow from the well and/or to facilitate injection operations.
Reaming: An operation to restore a wellbore to its original diameter (occasionally, a wellbore will cave in).
Shut-in: A well in which the valves in the production tree have been closed to cease production or injection operation on a well.
Sidetracking: The operation of deviating a well around a fish.
Spud: The initial penetration of the ground or seafloor - the start of the drilling operation.
Suspension/Suspend: The temporary cessation of drilling or production operations in a well.
Well workover: A program of work performed on an existing well.
Wellbore: The hole drilled by the drill bit.
Wellhead: Steel equipment installed at the surface of the well containing an assembly of heavy duty hangars and seals (the wellhead is used to support the weight of casing strings hung from it and to contain well pressure).
