Description
This unit of competency covers the skills and knowledge required to commission a well, its gathering system and their associated systems. It applies to operational commissioning which takes place after pre-commissioning of equipment and systems; pre-commissioning is typically performed by a contractor or projects team.This unit of competency applies to senior operators, field technicians and those in similar roles who are required to apply in-depth knowledge of process and plant to in order to bring a new (or worked over/rejuvenated) well and its gathering system on line, make adjustments to ensure it is in steady operation and delivering at the required rate, balance the impact of the new well on the entire system, and ensure the system is ready to be handed over to a field operator for normal operation.This unit of competency includes all such items of equipment and unit operations which form part of the well/system. A unit comprises two or more components of plant/equipment that are operated together to produce product, including as appropriate to the facility:wellheadschokes and control valvesmetersflow lineshigh point ventslow point drainsvalves, including non-return and pressure/vacuum reliefpumps and their prime moversproduct separation unitsinstrumentation and control systems (variable speed drive (VSD) and proportional integral derivative (PID))testing equipmentpower unitsdrive headsflaresfuel gas systemschemical injection equipmentfield flaresstorage tanks.No licensing, legislative or certification requirements apply to this unit at the time of publication.
