Through our many years of experience, the importance of mobile, robust and high quality CCTV camera equipment has become apparent for inspection of water bores, water wells, dewatering bores, pastefill holes, backfill holes and vent shafts. Whether the requirement is for bore diagnostics, downhole fishing, submersible pump installation problem diagnosis, or to verify construction details, a clear video is crucial in order to proceed with confidence.
Downhole inspection camera surveys are typically used for:
Part of AGE Development’s Downhole Inspection Service is to provide detailed custom design solutions to solve any downhole problem encountered. Combining AGE Development’s downhole CCTV inspection, design, manufacture, testing and onsite service abilities we are strategically placed to provide a complete service. Anybody can put a camera down a water bore, however our experienced technicians, state of the art technology and experience in clarifying silty/murky water and conditions alike means that a clearer picture is exactly what you get when you engage AGE Developments for your well inspection needs.
AGE has developed a fleet of fully equipped, purpose built camera vehicles and other transportable units, strategically stationed around Australia including:
In addition to our custom built borehole CCTV inspection units, we also have portable units available for dry hire.
Below is a brief overview of the varying downhole camera units available.

Large Diameter Raise Bore / Vent Shaft Inspection
AGE Developments has recently developed a high lux level downhole camera light module specifically designed to illuminate large diameter Raise Bore / Vent shafts in difficult lighting conditions. The developed light source results in clearer images and greater definition of rock features within large diameter open hole situations as seen in the attached 4.2m diameter shaft inspection.
AGE Developments conducts specialised fishing services to recover dropped electric submersible pumps, drill strings, drill bits, ESP cables, rocks, spanners and even mobile phones from within water boreholes. Utilising our bore CCTV camera inspection services coupled with custom manufactured water well fishing tools results in rapid recovery of even the most unusual items.
The attached video snippets show large diameter rocks and dropped pumps being recovered with the aid of hydraulic claw fishing tools in conjunction with downhole camera survey equipment.
Water Bore Screen Polymer Patch Repair
Water bore Polymer Patching is used to repair damaged downhole screens typically seen when a submersible pump is installed within the screened bore interval as shown at 46.1m depth in the attached borehole camera inspection survey. In this particular bore, an eroded pump bowl resulted in a HP jet that has blast eroded a subsequent localised hole in the stainless steel wedge wire screens.
The Polymer Patch is typically used for very short localised bore repair and results in minimal loss of internal diameter and a loss of only 300mm in production length to the screened interval.
Water Bore Swage Patch Reline Repair
Water Bore Swage Patch repair techniques are used to remediate localised damage within a bore casing or screen. This method is utilised where damaged sections are too long in length to utilise the Polymer Patch repair method.
The attached downhole CCTV inspection survey shows damaged caused by drill pipe rotating against the fibreglass water bore casing resulting in a longitudinal hole worn through the casing wall exposing formation material.
A stainless steel and vulcanised rubber stainless steel swage patch is installed and expanded radially to cover the damaged section and reinstate the integrity of the bore casing with minimal loss on internal diameter. The second half of the video shows the downhole camera inspection following the Swage Patch Reline Repair.
Water Bore Reline Repair is similar to Swage Patch Reline Repair however typically the entire steel or damaged sections of the bore are relined with stainless steel and vulcanised rubber patches to eliminate current or potential future corrosion damaged areas. This method is employed where the original bore casing is corroded or degraded from mechanical damage. The reline material is installed and expanded radially to result in minimal internal diameter loss (typically 8-10mm internal diameter reduction from original size).
As can be seen in the attached downhole camera survey, the stainless steel reline is overlapped and sealed into the stainless steel wedge wire screen to preclude any damaged areas from producing problematic formation material.
Paste Fill Bore Camera Inspection
Paste Fill Borehole CCTV Inspections are carried out to assess condition of the Paste Fill or Back Fill sacrificial casing and to confirm any leaks that may result in grouting of the sacrificial casing. The attached downhole camera inspection shows a vertically worn slot in the paste fill sacrificial casing which is typically a result of the backfill material freefalling at terminal velocity down the sacrificial casing.
Water Bore Cleaning Remediation
Bore Cleaning processes vary from bore to bore dependent on the fouling mechanism and fouling materials.
In the attached borehole camera inspection, heavy bacterial deposits were found within the screened interval of the water bore. A concurrent brushing and dual tube airlift cleaning processes was employed to remove the deposits before reinspection using the downhole CCTV inspection unit. Following the reinspection process, chemical treatment of the bore is undertaken to disinfect any remaining bacteria the mechanical cleaning process is unable to remove.
