Construct multiple aquifer production bores

Formats and tools

Unit Description
Reconstruct the unit from the xml and display it as an HTML page.
Assessment Tool
an assessor resource that builds a framework for writing an assessment tool
Assessment Template
generate a spreadsheet for marking this unit in a classroom environment. Put student names in the top row and check them off as they demonstrate competenece for each of the unit's elements and performance criteria.
Assessment Matrix
a slightly different format than the assessment template. A spreadsheet with unit names, elements and performance criteria in separate columns. Put assessment names in column headings to track which performance criteria each one covers. Good for ensuring that you've covered every one of the performance criteria with your assessment instrument (all assessement tools together).
Wiki Markup
mark up the unit in a wiki markup codes, ready to copy and paste into a wiki page. The output will work in most wikis but is designed to work particularly well as a Wikiversity learning project.
Evidence Guide
create an evidence guide for workplace assessment and RPL applicants
Competency Mapping Template
Unit of Competency Mapping – Information for Teachers/Assessors – Information for Learners. A template for developing assessments for a unit, which will help you to create valid, fair and reliable assessments for the unit, ready to give to trainers and students
Observation Checklist
create an observation checklist for workplace assessment and RPL applicants. This is similar to the evidence guide above, but a little shorter and friendlier on your printer. You will also need to create a seperate Assessor Marking Guide for guidelines on gathering evidence and a list of key points for each activity observed using the unit's range statement, required skills and evidence required (see the unit's html page for details)

Self Assessment Survey
A form for students to assess thier current skill levels against each of the unit's performance criteria. Cut and paste into a web document or print and distribute in hard copy.
Moodle Outcomes
Create a csv file of the unit's performance criteria to import into a moodle course as outcomes, ready to associate with each of your assignments. Here's a quick 'how to' for importing these into moodle 2.x

Elements and Performance Criteria

1. Plan and prepare for multiple aquifer production bores

1.1 Access, interpret and apply construct multiple aquifer production bores documentation and ensure the work activity is compliant

1.2 Obtain, read, interpret, clarify and confirm work requirements

1.3 Identify and address potential risks, hazards and environmental issues and implement control measures

1.4 Select and wear personal protective equipment appropriate for work activities

1.5 Discuss scope of work with client to gain general agreement on drilling plan

1.6 Obtain or sight any licences or permits required under the relevant State/Territory legislation or regulation.

1.7 Communicate and coordinate activities with others throughout the work activity

1.8 Obtain and interpret emergency procedures, and be prepared for fire/accident/emergency

1.9 Provide detailed strata logs, pump and development test results conducted during bore development and water and strata samples to the appropriate authorities

1.10 Complete all requirements for bore completion reports, decommissioning or abandonment and send to regulatory authorities within the time specified on bore licence

2. Design production bores for multiple aquifer systems

2.1 Determine most appropriate construction methods from the reading and interpretation of all available documented information and ensure relevant procedures and standards are adhered to

2.2 Design the bore to ensure the exclusion of unsuitable waters and to prevent the inter-mixing of aquifers with different water quality or Standing Water Levels

2.3 Select a bore site that will prevent contamination and minimise interference with other bores and that is safe with respect to potential occupational health and safety hazards

2.4 Select likely water entry mechanism from the formation to the bore such as open hole, slotted casing screens, gravel packs

2.5 Calculate appropriate artificial pack design parameters and recommended annular thicknesses required

2.6 Undertake calculations to determine appropriate screen design parameters (e.g. diameter, length, aperture size)

2.7 Plot and interpret sieve analysis results onto graphs

2.8 Select appropriate bore/surface casing for the anticipated ground/water quality and pressure conditions and any construction requirements

2.9 Ensure all necessary materials anticipated for the job are available and on site prior to commencement of construction phase

3. Construct production bores in multiple aquifer systems

3.1 Carry out any pre-start and start up procedures on plant or ancillary equipment

3.2 Identify, select and apply rig operational controls

3.3 Assemble and insert casing and screens

3.4 Grout or otherwise seal surface casing

3.5 Conduct grouting operations to seal intermediate and/or production casing strings or to seal selected zones

3.6 Construct bore in accordance with any applicable regulations, minimum construction and organisational requirements

3.7 Maintain plumbness and alignment of the hole within the required limitations

3.8 Collect, record and label formation and water samples

3.9 Maintain records accurately and legibly

3.10 Calculate hole, annular, fill or pack materials and mud pit volumes in cubic metres or litres

3.11 Select and place stabilising gravel fill as required

3.12 Determine appropriate artificial pack material grain size

3.13 Place artificial pack material in a manner that will ensure uniform distribution in the annular space without bridging

3.14 Maintain tool string inventories

3.15 Identify and protect headworks of the bore

3.16 Construct headworks to seal and cap the bore from surface water pollutants, environmental concerns and damage

3.17 Incorporate methods for measuring static and pumping water levels in headworks and for adequate sealing when not in use

3.18 Dispose of wastewater or hazardous materials from site and complete restoration of the bore site

4. Develop bore

4.1 Use development techniques with care to prevent collapsing of casing or screens

4.2 Use development techniques to improve hydraulic transmissivity around the bore

4.3 Undertake development until a continuous, clean supply of water is obtained, in accordance with site, contractual or regulatory requirements

4.4 Measure/calculate and record standing and drawdown water levels

4.5 Perform tests to estimate the sustainable yield of the bore

5. Disinfect/decontaminate bore and drilling equipment

5.1 Disinfect/decontaminate to comply with relevant standards or regulatory requirements

5.2 Handle hazardous chemicals in accordance with safety data sheets (SDS)

6. Carry out bore maintenance and rehabilitation

6.1 Carry out and shutdown procedures and secure equipment

6.2 Research all aspects of the bore construction and history

6.3 Undertake a process of diagnosis by testing and measurement to determine likely cause of bore deterioration

6.4 Devise a program of rehabilitation to ensure that the bore is restored to a reasonable condition

7. Decommission test/bore holes

7.1 Determine suitable decommissioning procedures and select appropriate sealing materials and placement methods

7.2 Carry out the decommissioning (abandonment) of test holes or bore holes in single and multiple aquifer systems

7.3 Seal bore with surface caps and cover borecap with 300mm local soil

7.4 Verify position/location of hole for future reference

7.5 Dispose of drill and other fluids safely
