In the world of mineral exploration and core drilling, achieving longer bit life and better core recovery is the key to efficient performance. Every drilling project faces unique challenges such as heat generation, friction, and poor flushing. These issues can lead to fast tool wear, unstable boreholes, and even core damage.
This is where drilling additives play an important role. These chemical compounds are specially designed to improve drilling efficiency, protect the tools, and help achieve cleaner, stronger core samples.
Let’s understand how the right drilling additives can make a real difference in your drilling performance.
Drilling additives are specially formulated substances mixed with drilling fluid or water. Their main purpose is to improve lubrication, cooling, and cleaning during drilling.
They reduce friction between the bit and the rock, stabilise the borehole, and carry cuttings away from the bit face. Additives are also responsible for reducing vibration, which helps maintain bit sharpness and enhances overall drilling control.
Simply put, they help your equipment perform better for a longer time.
When drilling in tough or variable ground conditions, the bit faces continuous pressure and high heat. Over time, this causes diamonds to glaze or dull, leading to slower penetration and poor core recovery.
1. Keeping the bit cool even at high rotation speeds
2. Reducing friction between bit and rock
3. Preventing clogging and bit balling
4. Enhancing water flow and debris removal
5. Protecting both the bit and the formation
All of this results in a smoother drilling process, longer tool life, and cleaner core samples.
During drilling, constant rotation and rock contact generate a large amount of heat. High temperature can damage the bit matrix and reduce diamond exposure.
Additives work as cooling agents and lubricants. They keep the bit temperature stable and minimise friction between the bit and the formation.
1. Preventing thermal cracking of the bit
2. Maintaining consistent diamond exposure
3. Improving cutting speed and efficiency
In some formations, particularly soft or fractured rocks, cores can easily break or get washed away during flushing. This leads to poor recovery and incomplete samples.
Drilling additives help maintain borehole stability by reducing fluid loss and sealing fractures. This keeps the whole wall firm and ensures that the core remains intact inside the barrel.
Better stability means smoother core extraction and higher-quality samples, which are essential for accurate geological analysis.
A clean borehole is important for smooth drilling. Without proper flushing, rock cuttings can build up and cause the bit to jam or wear out faster.
Additives help by improving the viscosity and carrying capacity of drilling fluid. They suspend and remove cuttings more effectively, keeping the bit face clear for uninterrupted cutting.
The result is improved drilling speed, better hole cleaning, and consistent performance throughout the drilling process.
Bit wear is one of the biggest cost factors in drilling operations. Constant friction and heat can quickly dull the diamonds and damage the bit crown.
Drilling additives form a thin protective layer between the bit and the rock, reducing abrasive contact. This protective effect increases the number of metres drilled before bit replacement is needed.
In simple terms, using high-quality additives means your bits last longer and your operational costs go down.
Every drilling site is different. Some formations are clay-rich, while others are abrasive or fractured. Additives are formulated to handle these variations.
1. Clay inhibitors prevent swelling and clogging in clayey formations.
2. Lubricants reduce drag in dense and abrasive rocks.
3. Foaming agents help manage fluid pressure in overburdened or loose zones.
By selecting the right additive blend, you can adapt your drilling system to any geological condition and maintain consistent performance.
