Optimising Water Bore Performance: A Comprehensive Guide
To maximise the production capacity of your water bore, start with effective bore development. This crucial process uses specialised chemicals and mechanical agitation techniques to enhance the performance of your bore and the surrounding aquifer.
Key Techniques for Bore Development
Air Development (Air-Lifting Agitation)
Air Development, also known as air-lifting agitation, stands out as one of the most effective methods for improving bore performance. This technique removes clay and silt particles introduced during drilling and finer materials from the aquifer surrounding the bore screen, significantly boosting bore efficiency.
Chemical Agents: AMC WELLCLEAN™
AMC WELLCLEAN™ plays a vital role in bore development. This chemical, designed specifically for bore cleanup, excels at breaking down the viscosity of bentonite-based mud used during drilling. It disperses any wall cake formed within the drill hole, ensuring a rapid and efficient cleanup process.
The Air Development Process
In the air development process, inject compressed air into the water bore to lift the water. Once the water reaches the top of the casing, shut off the air supply, causing the aerated water column to descend. Alternate this cycle with periodic air supply to continuously pump sediment from the water bore. Continue development until the discharge water runs clear and you have removed all fine materials from both the water bore and the adjacent aquifer.
Complementary Chemical Methods
Alongside air development, use chemical methods to enhance cleanup. Dispersants and detergents wet, break down, and facilitate the removal of clayey materials and fines from the formation. Employ mechanical means for the final development to ensure thorough cleanup.
Benefits of Bore Development
Enhanced Production Capacity and Stability
Proper bore development enhances production capacity and stabilises the formation. The formation acts as a natural filter, preventing sand from being pumped and causing severe damage to pumps and fittings. In most formations, applying appropriate development techniques results in a virtually sand-free or silt-free bore.
Longevity and Reliability
Investing in bore development ensures the longevity and reliability of your water bore system. Even in aquifers with exceptionally fine materials, you can achieve a balance to maintain an acceptable flow rate while ensuring a relatively sand-free water supply.
By prioritising effective bore development, you can optimise the performance and durability of your water bore, ensuring it operates at its best for years to come.
