Verified model comparison
Compare drilling-system architecture, rod package and site support before ranking pullback force.
The JT20 conventional reference and AT32 dual-rod system are different drilling packages. Obtain ground information, bore geometry and product requirements, then have the equipment supplier assess tooling and method. A larger thrust or pullback number does not establish a feasible bore.
Rod length, joint diameter and minimum bend radius constrain the equipment package. The published entry-angle values have their own setup bases; they are not a complete bore design. Both records retain unresolved setup-envelope measurements instead of deriving them from the stowed chassis.
Inspect rod threads and straightness, carriage/drive components, anchors, controls and maintenance records. Inventory locating, drilling-fluid mixing, recycling if required and transport equipment. Compare the complete crew package and documented condition without assigning unsupported fuel or production claims.
Generation/configuration-aware: measurement basis and reference configuration travel with each value. A difference in basis is not treated as a performance difference.
