Selecting the right system will depend on the drilling application or purpose. There are several factors to consider: the ground formation and type, the drilling method, whether a permanent or retrievable casing is required, the outside diameter of the casing, the wall thickness, the ring bit ID, as well as the casing and rock socket depth. Armed with this knowledge, we can then specify the appropriate system.
Below are examples of the most common applications:
Geothermal well drilling
The use of geothermal heating in houses has become increasingly popular as it provides both economical and environmental advantages for the user.
Casing advancement systems are useful when drilling a geothermal well as they keep the hole open during installation of the heat exchange system and minimizes any impact on the surrounding structures. It also prevents the collapse of the well during drilling where ground conditions are unstable.
Water well drilling
Water well drilling is commonly done in urban areas where drilling at speed is necessary to minimize disruptions to residents, as well as in the developed area where drilling is taking place.
In these instances, casing advancement systems are used to case the hole as it is drilled, providing stability for the hole, and preventing any collapse which could cause contamination of the water supply or damage to nearby city structures. This helps contractors to complete projects more quickly in urban areas, keeping disruption to a minimum.
Pipe Roofing
Tunneling can be both challenging and dangerous, and as more projects are undertaken in already developed areas where ground conditions are overburdened or weak, the issue of safety becomes even more pressing.
Tackling these challenges requires innovative methods of ground support, like pipe roofing, which reinforces the ground prior to the tunnel facing being installed. The steel casings are inserted during drilling in an umbrella pattern to form a protected arch above the advancing tunnel.
Casing advancement systems are used in this instance as pre-support structures during tunnel construction, making it safer for contractors to drill.
Foundation work
Reliable foundation drilling is essential to the success of any construction project. Drill rigs are used to bore huge holes deep into the earth's surface to insert piles that are the base upon which a structure is erected.
Anchoring
Tieback anchors are horizontal wires or rods that are used to strengthen and stabilize retaining walls during the construction process. They provide support for slopes and are anchored to the wall, connecting to a stable structure to provide individual or systematic support.
In most cases, casing advancement systems are used to keep the hole open during the anchor installation. This method is used when ground conditions are unstable to allow the installation of the tieback after drilling has been completed.
