The term slot recovery is of much significance for the operators of drilling the slot. This term is used to mean a process which involves removal of old and used conductor along with the inner strings of casing. They both are cemented to each other. They are to be removed safely and as quickly as possible. The task has to be completed within a short span of time. Multiple strings of casing that are cemented to each other are to be drilled so as to make a hole in them. Before the casing is laid down on the surface, they have to be cut down in to lengths that can be managed easily. In this process of drilling the casing, the important equipment used are drill presses. They are used to drill the casing from out side. In the first stage they have to be mounted on the outer surface of the casing. Then the drilling task has to be carried out. After drilling is done, the casing strings are pinned together. These multiple strings of the casing may be completely grouted to each other. kejuslot They may not be grouted completely in some cases.
Once the process of drilling is completed, the drill presses are removed and then the pin is installed. As a part of slot recovery, these tasks are to be done in a step wise manner. The pin that is placed here is intended to grant the facility of lifting device. Though it is a temporary purpose, the pin has to be effective. These kinds of effective pins will serve best as lifting devices though they are used temporarily. The main purpose of cutting the length of casing is to facilitate the process of handling the equipment. In this process, even multiple strings of the casing are also cut down in length. This is an essential part of the process to be carried out, since cutting the casing of multiple strings makes the lifting equipment to handle the casing easily and efficiently. Equipment used for lifting purpose will handle the casing of even multiple strings only when they are cut down to shorter lengths that can be managed easily. In the first attempt only some of the old and used casing will be removed. When the process is conducted for second time, some more part of it will be removed. Like wise the process is to be repeated for many times till the expected results are got. Old and used casing is to be removed by many repetitions of the task and finally a stage is achieved where there is no old and used casing present. This makes the slot to get rid of old and used casing as well as makes sure that it is empty. The main intention of this process is to clear the slot. Now, the slot can be availed for drilling programs.
