Tips For Installing Oil Well Casing

An oil well casing is a length of metal pipe that is installed within an oil well to strengthen the hole while simultaneously offering a measure of protection against oil leakage that could otherwise spill into ground water. The importance of casing pipe is quite significant because they prohibit gases from seeping into the well itself. Careful consideration is made prior to inserting one of these pipes into a well. Workers must first determine the appropriate casing for the particular job location and the materials that surround the well. There is a difference between an oil well casing that is used when the ground primarily contains rock and one that is used when the surrounding earth primarily contains soil.


Whether a drilling location contains rock or soil is also a factor to be considered when researching an oil pipe and well casing for sale. It is essential to procure the correct oil field tools for the job in order to ensure the success of the operation and the safety of the workers. Oil well casings are inserted into the well holes with the help of casing elevators on the traveling block. The drawworks and traveling block elevates the casing into position before placing it at the mouth of the well hole. Casing tongs are then used to screw one piece of casing into another and then lowered into the well.

Casing is run into the well and officially landed when the weight of the casing string is transferred to the casing hangers, which are located at the top of the well and use slips or threads to suspend the casing in the well.

There are four different types of casings using within a single well hole. The names of these casings are the surface casing, the conductor casing, the intermediate casing and the production casing. Once they are installed, drilling fluid is pumped into the casings. This drilling fluid will condition the mud. This is the last step before the casings are cemented into position. Once the cement has been poured, the casings need to be rotated. This ensures that the cement sticks the casing to the well hole itself. Most important, make sure that an experienced professional is in charge of installing the casings. This is not a task best left to amateurs.

There are many different types of casing and pieces of equipment involved in this process. When you research oil pipe and well casing for sale, you should also determine whether you need to buy any additional equipment to complete the task at hand. The job will be impossible to complete without all the necessary machinery and equipment, so you must be prepared before you begin the process.
