Standard HWDP
Standard HWDP was developed to provide a gradual transition from
heavy drill collars to relatively lightweight drill pipe.
This intermediate-weight pipe has a wall thickness of approximately
1 in. and helps prevent stress concentration at the top of the
drill collar section. Heavy weight drill pipe also enables drilling
at higher RPMs, reducing torque and differential pressure sticking.
Heavy weight drill pipe is well-suited for directional drilling
applications. Because it bends easily, heavy weight drill pipe
simplifies directional control and minimizes connection fatigue
problems that are common in high-angle or horizontal drilling.
For extended reach and horizontal wells, high-strength heavy weight
drill pipe is often used high in the hole to apply weight on the
bit. This is especially true for wells in which the total vertical
depth to total measured depth ratio is low.
