Required Skills and Knowledge

This section describes the skills and knowledge required for this unit.

Required skills 

Specific skills are required to achieve the performance criteria in this unit, particularly for the application in the various circumstances in which this unit may be applied. This includes the ability to carry out the following as required to conduct grouting or cementing operations in the drilling industry:

  • apply legislative, organisation and site requirements and procedures
  • apply communication procedures
  • use mixing equipment
  • measure tank dimensions and calculate volumes
  • calculate specific gravity of mixtures and hydrostatic pressures including pressure differences between anulus and inside of casing
  • record casing lengths and quantities accurately

Required knowledge 

Specific knowledge is required to achieve the Performance Criteria of this unit, particularly its application in a variety of circumstances in which the unit may be used. This includes knowledge of the following, as required to conduct grouting or cementing operations in the drilling industry:

  • site and equipment safety requirements
  • possible effects of grout, cement or cement additives on health
  • environmental requirements and procedures
  • team roles and objectives during the grouting or cementing operations
  • properties of grout, cement or cement additives
  • safe work procedure for the grouting or cementing process

Evidence Guide

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment 

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

The evidence required to demonstrate competency in this unit must be relevant to worksite operations and satisfy all of the requirements of the performance criteria, required skills and knowledge and the range statement of this unit and include evidence of the following:

  • knowledge of the requirements, procedures and instructions for conducting grouting or cementing operations in the drilling industry
  • implementation of requirements, procedures and techniques for the safe, effective and efficient completion of grouting or cementing operations in the drilling industry
  • working with others to undertake and complete the grouting or cementing operations that meet all of the required outcomes
  • consistent timely completion of grouting or cementing operations that safely, effectively and efficiently meet the required outcomes

Context of and specific resources for assessment 

  • This unit must be assessed in the context of the 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 workplace performance, including task skills, task management skills, contingency management skills and job role environment skills.
  • The assessment environment should not disadvantage the participant. For example, language, literacy and numeracy demands of assessment should not be greater than those required on the job.
  • Customisation of assessment and delivery environment to sensitively accommodate cultural diversity.
  • Aboriginal people and other people from a non English speaking background may have second language issues.
  • Assessment of this competency requires typical resources normally used in the work environment. Selection and use of resources for particular worksites may differ due to site circumstances.
  • Where applicable, physical resources should include equipment modified for people with disabilities.
  • Access must be provided to appropriate learning and/or assessment support when required.

Method of assessment 

This unit may be assessed in a holistic way with other units of competency. The assessment strategy for this unit must verify required knowledge and skill and practical application using more than one of the following assessment methods:

  • written and/or oral assessment of the candidate's required knowledge
  • observed, documented and/or first hand testimonial evidence of the candidate's:
  • implementation of appropriate requirement, procedures and techniques for the safe, effective and efficient achievement of required outcomes
  • consistently achieving the required outcomes
  • first hand testimonial evidence of the candidate's:
  • working with others to undertake and complete grouting or cementing operations in the drilling industry

Guidance information for assessment
