The Drill Pipe may sometimes be subjected to external pressure, which is higher than the internal pressure. This condition usually occurs during drill stem testing and may collapse the drill pipe. The differential pressure (external pressure minus internal pressure) required to produce collapse is calculated for various sizes and grades of new and used drill pipe …
The common drill pipe length is basically from 27-30 feet, which is classified as range-2 R2. This article will discuss their range and how to perform their design. What is The Common Drill Pipe Length Ranges The Drill String is made up of several sections of Drill Pipes. The term “stand” consists mainly of two …
To select the proper drill collar for the bottom hole assembly, we should understand what is the drill collar specifications. Generally, drill collars are identified by the following parameters: Drill Collar Sizes The hole size and bit program will determine the best drill collar size, but the collars selected usually have the largest OD and …
A drill collar is an essential tool used in oil and gas rigs for drilling operations. It has many functions, including providing weight on the drilling bit for efficient drilling and stability during operation. Understanding the importance of drill collars and how they work is vital for successful drilling operations. In this article, we will …
Heavy weight drill pipe (HWDP) specs are important to understand as they are the entrance to the heavy-weight drill pipe design & selection. This article will discuss its definition, uses, and advantages. Furthermore, we provided specification tables that will greatly assist in selecting the drill string design. In addition to that, you can also download …
We can define the drill string as a group of pipes and accessories on which the drill bit is run to the bottom of the borehole. These components allow us to deliver the rotation, the weight, and the fluids from the surface to the bottom of the drilled hole. It is an important part of …
A pipe sticking mechanism is something that is happening in the hole, which causes the force required to pull string to be greater than the weight plus the expected friction. In addition, the supporting force while running in will be less than the weight minus the expected friction. Sticking mechanisms can act while raising the …

Drilling slips are wedge-shaped segments with special dies inserted inside, which support the pipe when suspended in the rotary bushings. Figure 1 shows drill pipe and tubing slips with three body segments, while slips for drill collars and casing (Figure 2) are made up of many segments. Design The slips in the master bushing use …
