Mining, drilling and structural drilling supply
Mining operations rely on casing to stabilise drill holes, control ground conditions and maintain safe, predictable progress. We support mining and drilling buyers with heavy-wall casing, structural pipe and specialist grades suited to demanding ground conditions, operational pressure and project timelines.
Where Upstream Tubulars fits
- Heavy-wall casing and structural pipe for mining and drilling environments
- Useful for exploration drilling, pre-collars, overburden drilling and dewatering wells
- Commercial review of heavy-wall and project-driven pipe requirements
- Chrome and CRA discussions for corrosive or higher-pressure zones
Areas of particular relevance
- Exploration drilling and pre-collar supply
- Overburden drilling and casing-advance systems
- Dewatering wells, screens and slotted pipe
- Structural drilling and site-specific pipe supply
- Overlap with piling, water and industrial project needs
How casing is used in mining and drilling
Casing is installed as the borehole is drilled to prevent collapse, manage water inflow and support drilling through loose or mixed formations. Modern casing-advance methods can drill and advance casing simultaneously, helping to keep the hole supported throughout the operation.
Common approaches include dual rotary drilling, casing advancement systems such as ring-bit methods, and driven casing in very loose ground. Once casing reaches competent rock, drilling can continue inside the supported hole.
