This unit describes a participant’s skills and knowledge required to perform well servicing nippling-up and pressure testing in Drilling.

This unit is appropriate for those working in supervisory or technical specialist roles.

Licensing, legislative, regulatory and certification requirements that may apply to this unit can vary between states, territories, and industry sectors. Relevant information must be sourced prior to application of the unit.

Evidence is required to be collected that demonstrates a candidate’s competency in this unit. Evidence must be relevant to the roles within this sector’s work operations and satisfy all of the requirements of the performance criteria of this unit and include evidence that the candidate:

locates and applies relevant legislation, documentation, policies and procedures

works effectively with others to undertake and complete well servicing nippling up and pressure testing that meets all of the required outcomes including:

complying with written and verbal reporting requirements and procedures

communicating clearly and concisely with others to receive and clarify work instructions

communicating clearly and concisely with others to resolve coordination requirements throughout work activities

demonstrates completion of participating in well servicing nippling-up and pressure test that safely, effectively and efficiently meets all of the required outcomes on more than one (1) occasion including:

inspecting and adjusting equipment pressure ratings

carrying out nippling up of Blowout Prevention (BOP)

performing Blowout Prevention (BOP) and pressure testing

carrying out rig-up to drill out operations

processing written records and reports

The candidate must demonstrate knowledge of the following when participating in well servicing nippling-up and pressure testing:

accessing, interpreting and applying the organisation and site requirements and procedures

carrying out high pressure lines requiring pressure testing

knowledge and use of test equipment

testing equipment and procedures

rig maintenance procedures

identifying and managing surface production equipment

well head identification – pressures

well head identification – type (seal pockets, down hole gauges, stuffing boxes, DSA flanges)

re-pressure testing

manage and monitor nippling up and pressure testing within a team environment

identifying well head pressure ratings

pressure recording equipment operations

PSV ratings and operations

converting metric and imperial measurement

performing gas testing

performing a range of numerical calculations including:

volume

quantity

mass

weight

length

pressure

using calculator if required

using estimating skills (e.g. mental arithmetic, visualisation of size and quantity)

basic geometry (e.g. interpreting depth, direction, angles)

An assessor of this unit must satisfy the requirements of the NVR/AQTF or their successors; and Industry regulations for certification and licensing; and,

this unit is best assessed in the context of this sector’s work environment;

where personal safety or environmental damage are limiting factors, assessment may occur in a simulated environment provided it is realistic and sufficiently rigorous to cover all aspects of this sector’s workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills; and,

this unit must be assessed in compliance with relevant legislation/regulation and using policies, procedures, processes and operational manuals directly related to the industry sector for which it is being assessed; and,

assessment may be conducted in conjunction with the assessment of other Units of Competency; and,

assessment must confirm consistent performance can be applied in a range of relevant workplace circumstances; and,

assessors must demonstrate the performance evidence, and knowledge evidence as outlined in this Unit of Competency, and through the minimum years of current* work experience specified below in an Industry sector relevant to the outcomes of the unit; or,

where the assessor does not meet experience requirements a co-assessment or partnership arrangement must exist between the qualified assessor and an Industry subject matter expert. The Industry subject matter expert should hold the unit being assessed (or an equivalent unit) and/or demonstrate equivalence of skills and knowledge at the unit level. An Industry technical expert must also demonstrate skills and knowledge from the minimum years of current work experience specified below in the Industry sector, including time spent in roles related to the unit being assessed; and,

assessor and Industry subject matter expert requirements differ depending on the Australian Qualifications Framework Level (AQF) of the qualification being assessed and/or Industry Sector as follows:

*Assessors can demonstrate current work experience through employment within Industry in a role relevant to the outcomes of the Unit; or, for external assessors this can be demonstrated through exposure to Industry by conducting frequent site assessments across various locations.

**Where a unit is being delivered outside of a Qualification the first numeric character in the Unit code should be considered to indicate the AQF level

Foundation skills essential to performance are explicit in the performance criteria of this unit. Further information is available in the Resources and Infrastructure Industry Training Package Companion Volume.
