Free-bored refers to a drilling method used in the oil and gas industry to create boreholes without the use of a guide wall or pilot hole. This technique allows for the drilling of large diameter boreholes quickly and efficiently.
Typically, free-bored holes are drilled using a rotary drilling rig equipped with a down-the-hole hammer or tricone bit. The drill string is advanced without any casing or drilling mud, allowing the borehole to be created by the cutting action of the drill bit.
Benefits of Free-Bored Drilling
One of the main advantages of free-bored drilling is the ability to drill large diameter boreholes in a single pass. This can significantly reduce drilling time and costs compared to traditional methods that require multiple passes to reach the desired borehole size.
Challenges of Free-Bored Drilling
While free-bored drilling offers many benefits, there are also some challenges associated with this method. One of the main challenges is controlling the deviation of the borehole, as the absence of a guide wall or pilot hole can lead to deflection from the intended path.
Another challenge is maintaining stability of the borehole walls during drilling. Without the support of casing or drilling mud, there is a risk of borehole collapse, especially in unstable formations.
Applications of Free-Bored Drilling
Free-bored drilling is commonly used in the oil and gas industry for creating large diameter boreholes for groundwater monitoring, well abandonment, geotechnical investigations, and mineral exploration. This method is also used in civil engineering projects for creating boreholes for foundations, tunnels, and other underground structures.
In conclusion, free-bored drilling is a versatile technique that offers many benefits for creating large diameter boreholes quickly and efficiently. While there are challenges associated with this method, advancements in drilling technology continue to improve the capabilities and reliability of free-bored drilling.
