Inclined and horizontal drilling poses greater challenges for borehole guidance and core transport. Core quality, stability, and documentation are a given in vertical drilling. In horizontal drilling, however, they become a challenge.

STUBORE® handles this with a continuous double-core tube: The core remains protected during drilling and is guided independently of the rotation. The continuous casing stabilizes the borehole even under difficult ground conditions, such as when drilling beneath buildings, roadways, or contaminated areas. 

Advantage of STUBORE®: Fully cased horizontal boreholes—stable, clean, and capable of precise stratigraphic documentation, regardless of drilling direction and subsurface conditions.
