Casing-while-drilling alloy casing bit
Drill while casing with an alloy PDC bit that can be drilled out after cementing.
The Allegro XCD-Pro casing-while-drilling expert service provides a comprehensive application analysis to identify and mitigate drilling risks. Leveraging a suite of software simulation solutions, including the IDEAS integrated dynamic design and analysis platform, the service evaluates conditions such as formation strength and bit-to-rock interaction to design an ideal bit cutting structure with unique diamond cutting elements.
With bit customization, the Allegro XCD-Pro service delivers greater reliability and performance during casing-while-drilling operations.
Casing while drilling smears cuttings into the borehole wall, resulting in an action termed the plastering effect, which strengthens wellbores for improved cementing. The plastering effect process has proved to reduce NPT resulting from borehole-related problems, such as
large-diameter surface hole resulting in hard-to-remove cuttings from the annulus
damaged producing zones
As part of the Allegro XCD-Pro service, casing-while-drilling operations are further optimized to help mitigate risks before you drill. With a prejob analysis and bit and BHA customization, you can reach TD safer and more efficiently in any drilling application.
Comprehensive risk analysis conducted by Allegro XCD-Pro service enables drilling to TD in a single run.
