Application

Typical Wellbore Construction & Casing Application

Our Casing pipes are engineered to support the entire lifecycle of the well, from spudding to production. As illustrated in the diagram, we supply a full range of OD sizes for different casing layers:

1. Conductor Casing: The first string set to protect surface formations and prevent washout.

2. Surface Casing: Crucial for isolating freshwater zones and providing a foundation for the blowout preventer (BOP). Our pipes grades are widely used in this section.

3. Intermediate Casing: Installed to seal off unstable hole sections or abnormal pressure zones before drilling deeper.

4. Production Casing: The final string that isolates the production zones and provides a conduit for oil and gas to the surface.
