There are a number approaches to drilling, the one you select will depend on a number of factors: what your eventual goal is, the type of soil or surface you are drilling through, the availability of certain tools, your budget… the list goes on and on.
Today we will be talking about a drilling solution that works best for unstable ground and soil conditions; namely, mud rotary drilling.
How Does it Work?
Mud rotary drilling is a technique developed well over a century ago, and in that time has become a popular approach for drilling, particularly in the presence of unconsolidated ground formations such as soft rock, or minerals that are not in layers.
Through this approach, fluid is pumped down a hollow drill pipe from where it carries cut minerals back up to the surface, where it is retained in a mud contamination system or pit.
From there it travels back to the kelly and bit through a suction hose. After the Kelly has been drilled all the way down, a 20 or 40 inch drill pipe is used to start the drilling process again.
The fluid used in this type of drilling contains bentonite or polymer based additives that create a film of ‘wall-cake’ in the hole as it is drilled, this services to stabilise the terrain being worked on.
The Benefits of Mud Rotary Drilling
Mud rotary drilling holds a number of advantages. For starters, it is faster and more efficient than many other types of drilling, it is also perfectly applicable across a range of soil types, including those that are unsuited to air rotary drilling practices.
