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 …

The aim of the WEATHERFORD Technical Data Handbook is to provide comprehensive information to personnel involved in oil and gas well drilling, production, completion, and workover operations. This handbook is a compilation of data from various sources within the petroleum industry. While every effort has been made to ensure accuracy, WEATHERFORD, its agents, or subsidiaries …
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 …
In case of a drill string failure, such as pipe washout or twist-off, it is crucial to determine the cause of the failure to prevent it from happening again. This text covers the most common failure mechanisms, of which there are over a dozen, and provides a general understanding of what to do in each …
Guns normally run on wireline or tubing can also be run using coiled tubing allowing through tubing perforating to be carried out in horizontal wells. An electrical wireline can be installed inside the coiled tubing to allow depth correlation with casing collars or a gamma ray and the use of electrically initiated detonators. Here, we …
A wiper trip is often made before running the casing. This is because it is essential that the casing, once started in the hole, reaches the planned casing setting depth with minimal trouble. Therefore, the hole must be in the best possible condition before running the casing. Procedure On the last trip out of the …
