Drill Pipe Selection Guide



Failing Exploration Thread /Failing Thread /Fedp Thread Drill Pipe

Drill pipe is one of the necessary components to any drilling rig designed to extract oil or other liquid materials from the ground. The drill pipe is not used for extraction. Instead, the hollow tubes pump drilling fluids downward to the bit and back out again as needed to reduce friction and heat buildup.

Drill pipe designed to deliver value At Grant Prideco, it’s our mission to increase efficiency, improve performance, and reduce your total cost of ownership. From the design room to the wellsite, we produce the industry’s highest-quality, innovative drill pipe technologies that will help you achieve lasting success.

Standard drill pipes are long tubular sections of pipe that make up the majority of the drill string. They are typically a 31 foot long section of tubular pipe but may be anywhere from 18 to 45 feet in length.

Heavy weight drill pipe (HWDP) is a tubular pipe that adds weight or acts as a transitional piece in the drill string. As a transitional section of the drill string, it is placed between the drill collar and standard drill pipe to reduce fatigue failures. In other applications the HWDP is used as an additional weight to weigh down the drill string.

1. Drill pipe is designed to allow the introduction of a drilling fluid or air to the bit and to provide the mechanism to transfer energy developed by the drill motor to the bit.   

2. The correct selection of drill pipe, in most instances, determine how successful you are and what options you have as far as depth, bore hole size, and push and pull down ability.   

3. The selection of drill pipe is one of the most important decisions mainly due to cost and rig capability.  

Below is a breakdown of what the most popular drill pipes are and their benefits.
