It can be used in foundation construction, Piling, Water Well and Geothermal, Tunneling and Horizontal drilling. Specially the rock formation is not stable with fractures.
RFQ:
1. What is the purpose of surface casing?
Surface casing is set to provide blowout protection, isolate water sands, and prevent lost circulation. It also often provides adequate shoe strength to drill into high-pressure transition zones.
2. What is overburden mine?
In mining, overburden (also called waste or spoil) is the material that lies above an area that lends itself to economical exploitation, such as the rock, soil, and ecosystem that lies above a coal seam or ore body.
