Heavy Weight Drill Pipe (HWDP)

Heavy weight drill pipe (HWDP), also known as hevi-wate, is a vital component in oil and gas drilling operations, particularly in directional drilling. Its flexibility and strength make it ideal for the vertical section of boreholes, providing weight on the bit while maintaining more flexibility than a drill collar. In addition, Heavy weight drill pipe is well-suited for directional drilling applications due to its bending capability, providing enhanced directional control, minimizing connection fatigue, and allowing for smoother drilling in high-angle or horizontal scenarios. If you’re looking to rent HWDP for your drilling operations, explore our available sizes to find the perfect fit for your needs

Key Features of Heavy Weight Drill Pipe

"Center Upset" or Wear Pad

HWDP is equipped with a wear pad, known as a “center upset,” that protects the tube from wearing on the outer diameter and minimizes hole drag and differential sticking problems. The design of the wear pad increases tube life and contributes to smoother drilling operations.

Thicker Walls and Longer Upsets

We offer drill collars made from plain carbon steel or non-magnetic alloys, such as copper-steel composites, ensuring longevity and maintaining non-magnetic properties.

Flexible Transition

HWDP serves as a flexible transition between drill collars and drill pipe, reducing fatigue failures above the Bottom Hole Assembly (BHA) and ensuring a seamless drilling process.
