Boreholes may experience reduced performance over time due to mineral scaling, bacterial growth, and debris buildup, making periodic cleaning essential to restore optimal flow and efficiency.

Chemical Cleaning Methods
Chemical treatments are used to dissolve or eliminate internal blockages within the borehole system, including:

• Acidisation: The controlled introduction of acid to dissolve calcium carbonate and other mineral deposits that can obstruct fractures and reduce fluid flow into the wellbore.
• Biocide Treatment: Applied where bacterial contamination has led to biofouling of the borehole screen or formation, restricting movement of fluids into the tubing system.

Mechanical Cleaning Methods
In cases of heavy buildup or physical obstruction, mechanical intervention is required as a first-stage remediation step, including:

• High-Pressure Jetting: Used to dislodge and flush out sediment, scale, and loose debris from borehole walls and screens.
• Mechanical Scrubbing: Specialized tools are deployed to physically remove hardened deposits and restore borehole integrity prior to chemical treatment.

Together, these methods ensure improved borehole performance, restored yield, and extended operational lifespan.
