Mobilisation
Activity
1. Contract
-
Contract signed
2. Program of work
-
Program of work submitted and approved
4. Equipment is appropriate and in working condition
-
Drill rods are adequate
-
Hammers and bits are of the right diameter (measure)
-

Drilling
Activity
1. Health and Safety
-
Rig set up away from traffic hazards and power transmission lines
-
Rig and support vehicle not positioned on a steep slope
-
Public safety barrier (bright coloured tape).
-
Drilling team wearing personal protective clothing: boiler suits, hard hats, boots, eye protection and gloves
-
Inflammable items such as petrol or chlorine etc should be kept in approved containers, properly marked and stored away from sources of heat.
-
Mast not raised during thunderstorm (lightning strike risk)
-
Lifting of very heavy or bulky loads which could lead to back strain should be avoided. Lifting should be done using the legs and not with the back.
-
Equipment should be kept in good working order.
-
Area around the drilling rig is kept tidy.
-
Borehole should be securely capped on completion to prevent tools and other debris falling into the hole and children throwing stones and corn stalks into it which could render it useless.
-
On completion, the site should be restored as far as possible to what it was before the drilling, mud pits filled in and compacted.
-
Drill crew should drink plenty of fluids regularly to prevent dehydration, which can lead to poor judgement.
-
First Aid kit checked
-
Emergency procedure in case of major injury and need for hospitalisation are in place
2. Rig position
-
Rig positioned over pegged site.
-
Rig drill mast vertical (checked with spirit level).
-
Check ground stability for softness that could entrap the rig or cause it to tilt during drilling
3. Drilling Depth
-
Depth measurements being conducted and logged properly
4. Penetration Rate
-
Penetration rates being measured properly
5. Drilling Fluid
-
Type of drilling fluid being used:
-
Driller using Marsh funnel to measure drilling fluid viscosity
6. Drill Cutting Samples
-
For Rotary mud-flush drilling, check that the circulation mud pits (or portable tanks) have a volume that is at least three times the volume of the borehole
-
Ensure that the Driller prevents sample contamination due to poor circulation, borehole erosion or caving.
-
Ensure that mud pits are kept clean to prevent re-circulation of cuttings.
-
Samples taken at regular intervals and properly washed, bagged, labelled, logged and stored in sample box.
-
Photograph samples
7. Strata Log
-
Use samples to prepare a Strata Log
8. Final borehole depth
-
Water table depth (m):
-
Final borehole depth (m):
9. Drill Report
-
Daily drilling log signed by rig operator and Supervisor.
-
Record necessary data and information required to complete a Casing and Well Completion Form
Demobilisation
Activity
1. Work complete
-
All installation work complete and approved by Supervisor
-
All testing completed and documentation and data handed over to Supervisor
2. Drilling site cleared
-
All litter, liquid and solid waste disposed of responsibly so as not to cause nuisance
-
Circulation pits filled in
-
Equipment cleaned and packed away
-
Unused materials taken away (check with contract who owns or pays for unused materials, such as casing, filter packs etc.)
-
Public barrier taken down
Development and Site Completion
Activity
1. Reporting
-
Drilling report completed and copies given to Client, the Community and the Regulator/Government water or geology ministry
2. Handover
-
Agree handover date with Driller, Community and Client.
-
Organise signed handover of borehole to the Community or Client
3. Defect Liability Period
-
Agree monitoring schedule.
-
Undertake site visits to check that pump is still working and that there are no problems with the borehole performance.
-
Report any problems found, or reported by the Community to the Client. If necessary, mobilise the Driller to undertake repair work.
4. Invoicing and payment
-
At end of defects liability period, submit supervision invoice to Client and give approval for final payment to Driller (depending on contract).
