Cirrus can offer any of the following CCTV services:
Cirrus can inspect boreholes of diameter from 50mm to 1000mm diameter and up to 300m in depth. All CCTV inspections are recorded in PAL at full colour to DVD. A copy of the DVD can be archived with Cirrus and made available for clients if they require copies in the future.
Cirrus can either provide unreported or reported CCTV surveys using our in house team - this can accompany any of our other hydrogeological services. For those who need existing CCTV surveys transcribed Cirrus can transfer VHS or Betamax to any digital format (.ISO, .DAA, .IMG) or any physical digital format (DVD or Blu-ray disk).
Borehole rehabilitation can take many forms. At Cirrus we utilise the most effective and proven methods to generate the best possible results for any budget, from brushing, acidisation, to pneumatic impulse systems.
Cirrus has a proven track record with experience of treating hundreds of boreholes worldwide.
Cirrus can offer a full range of downhole geophysical services such as calliper, gamma, temperature & flow logging. This can be offered as a standalone or packaged service.
We also now offer a 3D modelling and visualisation service for boreholes. Depending on the data available these can be accurately scaled to the millimetre allowing them to be used for anything from marketing displays to engineering aids to proof of concept visuals.
Cirrus has an in-house team with years of experience in controls electronics. We can deliver solutions for single boreholes to well fields with both local and remote monitoring using anything from tied and proven to cutting edge technologies.
Jetting and pigging is service Cirrus recently branched into. We felt our clients weren't feeling the full benefits of our rehabilitation services, Specifically those clients who gauged asset performance by only water quality. On many occasions a boreholes performance was being hindered, and pumps were requiring more frequent services, and this was due to the raw water transmission pipework being severely constricted by mineral build up and biofouling.
Hydraulic testing is the best way to quantify a boreholes performance and a key indicator of how successful any rehabilitation or yield enhancement has been.
Cirrus is currently working on strategic partnerships with specialist chemical engineering companies to bring the latest and best chemical products to the U.K. water industry.
Airbust is a 4 stage process
The AirBurst process is repeated throughout the borehole until all treatment areas identified under the AirBurst schedule have been rehabilitated or developed to the best possible condition. The process can be customised to concentrate on areas for fracturing or fissure expansion e.g. "hydro-fracturing" to increase the borehole yield where desired. Any dislodged sediment, mineral scale and biofouling removed by AirBurst from the well screen, gravel pack or rock formation then falls to the borehole base where it is removed by airlifting or by using a submersible pump. Once the AirBurst process has been completed and the particulate matter removed from the borehole, a post-AirBurst CCTV survey is completed for comparison and analysis. Both pre- and post-AirBurst CCTV surveys and the process analysis then forms parts of the AirBurst borehole report for the client. In addition to the AirBurst process, a package of hydraulic performance testing can be undertaken to quantify in detail the effectiveness of the rehabilitation and/ or development of the borehole. The test data can then be analysed and fully interpreted by our specialist hydrogeology team and included within the AirBurst borehole report. The AirBurst process can take as little as one hour with complete site-based remediation usually lasting no more than a day. Where local conditions allow, Cirrus can treat multiple borehole sources in a day.
Case Study PDF's
AirBurst can and has been used in both cased and uncased vertical boreholes, inclined boreholes and radial wells/infiltration galleries.
AirBurst has been used in boreholes from 100mm (4"In) to 2m (6"Ft.).
Cirrus's current rig allows for depths up 300m (980"Ft.) however this can be extended to 1km+.
Yes, obviously there are limits to how much energy can be used and it is more dependant on the condition and thickness of the casing than with steel or stainless steel cased boreholes.
No, Airburst is a compressed gas process involving either air or nitrogen
We would always suggest AirBurst as the first treatment to be used, and then if necessary a chemical product. Using any chemical product after Airburst should; enhance its performance as Airburst would have removed any blockages and thus opened up pathways for chemicals to travel further in the borehole, the borehole annulus and the formation. If Airburst is used at the same time as chemicals; then the process will distribute the chemicals very effectively and much quicker than waiting for dispersion alone.
