A stuck pipe can be a very frustrating problem to solve, regardless of how experienced you are in plumbing. This is true for both novice and experienced plumbers. There are a lot of possible scenarios that could result in a pipe getting trapped. To name a few of these causes, we have mechanical sticking, instabilities in the borehole, ledges, and doglegs.
The oil and gas business has a significant challenge whenever a pipe becomes clogged. In most cases, the costs associated with this kind of issue might range between $200 and $500 million per year. You will be relieved to know that there are a few measures you can take to cut down on the amount of pipe sticking that occurs over the course of your drilling activities.
The first thing that needs to be done is to locate the offender. It's possible that this is a piece of rubbish that's been riding atop your drill bit, or it might be a block of rock that's preventing the drill string from advancing. It's also conceivable that the hole you're getting is too tiny for the bottom hole assembly you have (BHA).
The following thing that needs to be done is to discover out what the root of the issue is. Investigating the mechanical characteristics of your mud can help you gain a better grasp of the situation. You also have the option of conducting some of the examinations in a laboratory. The findings will inform you what your drill string is capable of and what adjustments need to be made in order to get it back into operating order.

Ledges and doglegs, which are often missed, can be a pain in the neck for the operator of the drill string as well as for the drill string itself. To our good fortune, there are a number of measures that can be taken to reduce the danger. The most effective tactic is to remain constantly aware of the circumstances, making it a priority to maintain both your feet on the ground and your eyes on the prize at all times.
Being proactive and taking the time to identify and address the reasons of a clogged pipe is the most effective method to avoid having to deal with one of these types of problems in the first place. One of these steps is to find future problems and find solutions to those problems using a machine learning approach. The most effective machine learning methods are able to examine hundreds of wells and thousands of wellbore logging data sets in order to isolate and rank the most likely offenders. The findings are easily exportable to share with the other stakeholders and may also be saved for future reference.
Identifying the most optimal formations for casing string replacement and lateral tieback can also be accomplished with the assistance of a machine learning system. In the event that a pipe becomes clogged, the most effective solution is to rotate the forming points in order to alleviate the situation. Rotating the drill bit is one of the most successful ways that may be used. A BHA should be used to impart weight to the drill bit, which is another precaution that should be considered.

There is the potential for a variety of unstable conditions to manifest themselves whenever there is a differential stuck pipe that is lodged in the borehole. Some of these instabilities are incapable of retaining their original dimensions and configurations. The consequences of these imbalances can have catastrophic results.
High stress formations, ground movement, water absorption, overburden, and an inadequate amount of mud weight are some of the most significant factors that contribute to wellbore instability. These factors can have an effect on the wellbore's dimensions, as well as its size and circulation.
Shale formations can become unstable in certain circumstances. Because of this, the formation may shatter into enormous fragments that then fall into the wellbore. In addition to this, it has the potential to cause issues with the casing and logging tools.
In addition to these primary factors that contribute to wellbore instability, a variety of other local factors can also bring about wellbore instability. Most of the time, weak bonding between the formation and the support is to blame for these localized instability issues. On the first day of drilling, these local instabilities are difficult to identify since they are so small. It can take a few days for these instabilities to manifest themselves.

The diagnosis of a casing pipe that is stuck can be performed with a few different tools. The pipe recovery log and the free point indicator are the instruments that are utilized the majority of the time. Determine the severity of the stuck condition by using the recovery log tool, which is calibrated in the bottom of the surface pipe and is used to extract stuck objects. In most cases, it is carried out in conjunction with the gamma ray log. The gamma ray log will be able to identify the sort of formation that is causing the pipe to become stuck, which will assist in selecting the most effective solution. A free point sensor and a power module are the two components that make up the free point indicator. Both the working line and a slickline are connected to the tool that is being used. The magnetic permeability of the oil field pipe is measured by the tool, and the results of the measurement are compared to those of the first set of measurements. The free point can be determined based on the amplitude of the return echo pulse.
The indication for the free point can also be fastened to the slickline if desired. The instrument gathers two different sets of data and then compares them on the surface level. It is possible to read these logs even before the pipe has been recovered.
