apply basic drilling fluid tests such as viscosity and specific gravity

apply core handling and tray placement requirements and procedures

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 wireline core drilling

configuration requirements of various thread forms and makeup torque requirements

function of hole collaring use of casing and collar sealing techniques

methods required to produce uncontaminated samples

impregnated bit stripping procedures

bit selection for different types of drilling and different ground conditions

measurement of bits and other related components

critical dimensions of a core barrel if barrel has to be drilled through to reduce hole size

relationships between penetration rate and bit life

role that core blockages play in affecting sample quality

functions of drilling fluids and control procedures

relationship between hole diameter rod diameter pump output and the specific gravity of formation cutting

types of mud and water delivery pumps and their applications

hazards associated with wireline operations and control measures required

purpose of drill hole surveys and the functions of azimuth and dip readings and where it is applied

core orientation and where it is applicable

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 wireline core drilling

implementation of requirements procedures and techniques for the safe effective and efficient completion of wireline core drilling

working with others to undertake and complete wireline core drilling tasks that meet all of the required outcomes

consistent timely completion of the wireline core drilling that safely effectively and efficiently meets 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 andor 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 andor oral assessment of the candidates required knowledge

observed documented andor first hand testimonial evidence of the candidates

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 candidates

working with others to undertake and complete the wireline core drilling tasks
