Wireline tool such as logging tool, slick line tool can be stuck in the hole therefore we need to understand about wireline recovery tool. This article demonstrate typical wireline fishing / recovery tool. Common wireline tool issues center around the cable being tangled or wadded in the hole, as well as the fact that attempts at fishing can pull the wireline out of the rope socket or part, further complicating tool retrieval.
Stuck Cable or Tools
As soon as a wireline assembly becomes stuck, the operator will need to determine whether the problem is in the cable or the tool. Usually, one would apply normal logging tension on the cable and allow it to sit for a few minutes. During this time, four things should be recorded:
the current depth of the tool
the type and size of the cable
the surface tension of the cable just prior to becoming stuck
In technical terms, a fish can be any object which has been lost or stuck in a borehole, and has a serious negative impact on well operations. Fishes can be anything, whether that is a drill string that has come away, a bit cone, or even a hand tool that has been inadvertently dropped into the well. To solve this issue, fishing involves the use of special tools and procedures to recover the fish and allow drilling to continue. While this article will deal solely with regular fishing, there is also an alternative method, which involves using through-tubing processes that make use of tools on a wireline or coiled tubing.
Virtually any object that is dropped into a well, or even run into it, may need to be fished out at some point. Furthermore, the need for fishing may arise at any given point during operations, and there are therefore a wide range of different tools and methods. There are three main technologies that these solutions are built around, though: pulling, milling, or cutting the pipe itself, and other downhole parts.
A fishing job is one option, but this will depend on the cost and likelihood of success. Other options include:
Leaving the fish where it is, and sidetracking or redrilling the well to follow an alternative path
Leaving the fish where it is, and completing the well in a shallower zone
Abandoning the well altogether
Preferably, the fish should be completely avoided in the first place, thanks to the right planning and proper drilling practices. However, it is important that a contingency plan is in place should the situation arise. Continue reading →
Cased hole finishing is quite different in term of operation, tools and techniques so people need to fully understand about this topic. The cased hole fishing video training by Weatherford is the last video training for the fishing operation series. This will help you understand about overall about cased hole fishing in many aspects.
Open hole fishing is one of the most time consumed operation because it involves a lot of unknown down hole conditions. In order to have successful fishing operation, it is imperative to fully understand about the open hole fishing tool. The video training below provided by Weatherfor is considered as one of the best fishing operation video training. Additionally, the full video transcription is provided to help people understand this topic.
One of the advantages of wireline tool is to be used as a part of finishing operation. This video provided by Weatherford will guide you to understand about wireline tools and their functions in the fishing operation. We also include the full vdo transcript in order to assist learning of people in our industry as usual.
