One of the things required in doing oil extraction from any source requires the drilling of a well. To prevent the oil from leaking into the environment as well as the contamination of it by fluids or mud found on the walls of the well, with the aid of the casing puller, the casing of the well needs to be done. When the puller, sometimes referred to as lift nubbin or lifting cap is used, it makes the process easier.
To get to the oil, considerable amount of pressure is involved to drill beyond the lithosphere and other layers of earth and this must be factored in. The well may suffer collapse and cave in on itself, when it happens like that the oil stream is closed off, if the pressure is not constantly monitored. One way to strengthen the wall of the well is to insert big steel pipes into the bore of the well. This will in the long run prevent the well from caving in.
The pressure used in the extraction of the oil need to be watched constantly, so that the well does not collapse and cave in which will prevent the flow of oil. To sure up the walls of the well, a tube can be inserted into the drilled hole that will reduce any chance of the walls caving in.
The well's borehole can be drilled either vertically or diagonally and have steel pipes installed in it all the way to the base. The pipes are usually 40 feet long and are threaded in order to be able to be connected and form a chain or string. Each pair of pipes is then connected by what is called a collar.
The pipes are inserted into the well all the way to the reservoir and at this point a test pump is done. This is to check that the casing is functioning properly and there is no leakage, as well as to be able to remove any contaminants that might be there. To do this, the drill bit is put into the pipes together with drilling fluids. A large amount of drilling fluid is pumped in during the cleaning process.
A test pump is done after the pipes are positioned in the well all the way down to the reservoir. This is to make sure that the casing is working correctly with no leaks and also to remove any debris that could contaminate the oil. The drill bit is attached to the pipes alongside the drilling fluids. To clean the pipes, the fluid is pumped for a considerable period of time.
After each stage of the drilling process casing is carried out. It therefore means that cement is also added and that the drilling is also done in stages in conjunction with the inserting and cementing of the steel. This results in having the casings uniformly matched to fit from one stage to the next.
While the drilling is being done, any need for an extra case will be spotted. The steel pipe installed in the borehole at this juncture is called intermediate casing. It is done at the first sign of any weakness in the original casing caused by the drilling. The intermediate casing is supposed to strengthen that area.
