Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

Instructions to Assessors

Required Skills and Knowledge

The candidate must demonstrate the ability to complete the tasks outlined in the elements, performance criteria and foundation skills of this unit, including evidence of the ability to:

conduct mud rotary drilling on at least two occasions, including:

planning and preparing for mud rotary drilling, by:

developing a work plan for a hole, outlining:

environmental practice

health and safety considerations

target depth

construction materials to be used

equipment to be used

mud design

grouting if required

conducting pre-start and shutdown checks

making up and checking drill string and down hole assembly for wear, gauge and damaged threads to ensure components are in suitable condition

operating mud rotary drill, including:

designing and adjusting mud system to suit geological conditions and changes to conditions during drilling, including:

lost circulation

water supply

flow rates

fluid cleaning

hole stability

conducting sampling to confirm drilling fluids are suitable for application by testing:

density

pH levels

velocity

pressure control

weight control

filtration levels

monitoring and adjusting up hole velocity as required

installing collar casing and seal
