Understanding float collars better

 Have you ever seen a closing collar that is attached to the bottom of the casing string? This usually is a cementing component. This is the float collar and it is extensively used in multiple places. With its extensive application, it is also used in several verticals. But the primary function of this collar is not what people usually think about it. The basic function of a float collar is to become a landing spot for all the cemented plugs that are installed in the primary well cement. This collar is installed to prevent the flow-back of the fluid during the running operations 

What is the operation of float collars?

There are a lot of operations where float collars are the small sections of the casing having tool joints on both its ends. The backpressure valve is also integrated into the float collars and this is one of the most often found in either a flapper type or a spring-loaded valve. 

What do you understand about case running?

The case running is a process in which the casing string is inserted into the open wellbore that is available. There is Derrick support that’s available in the hub which supports the weight of the top portion in the casing string. 

Conclusion

A float collar is now available in different options and one can find it in a lot of places being used. There are a lot of performance features that are related to the float collars. The collars also have free-floating abrades making it a useful product so much more than people assume it to be. 

So while you think that float collars are not a useful product, think twice about this decision and see for yourself how it is being used in various sectors. If it has any application or not. Given above is the information that you need to know about it.

Are the casing centralisers really a boon?

 A lot of technology and gadgets are created every other day. Little is known to people that not all of them are helpful to them. Also to perfect a machine or equipment one has to take a lot of turns. The same happens with casing centralisers. A casing centralizers is a device that is mechanically operated and is used to prevent the good casing from touching the side walls. This casing is important from a construction point of view because it gives the drilling team a complete 360-degree turn to complete the process of cement application or whatever is needed for completion. 

Here is some important information about casing centralisers that can help in understanding that they are really a boon or just a hindrance in disguise?

Are these centralisers really required?

A lot of state and federal companies and agencies have said that centralisers are required for some drilling projects. This is, more importantly, true for the projects where annular space is an essential thing for the project. 

How are the centralisers applied in a well?

A spring centraliser comes in two variants, the first being hinged and the second slip-on. The hinged casing comes with a crew assembly and it is attached with the help of hinged pins. Whereas on the other hand, the slip-on centralizer has a solid ring design with both ends attached to the borehole. 

How are the users benefitted from the centralisers?

Whenever the builders are setting the well casing, there are a lot of things that have to be kept in mind. If after considering all those things you place a centraliser in the well, there are ample advantages that you can get from it.

● The casing works as a strengthening point for the well so that there are no problems in terms of rupturing the well at any point.

● When the casing is run into the borehole, it reduces drag that could have been caused otherwise. 

● The wellbore caking is also prevented when the casing centralizers are installed in a well.

Now, these might be just a few quick facts but for people who still don’t trust the casing centralisers; they can rest assured that these are boons and nothing else. One can enjoy a lot of perks amongst which the three mentioned above are the most important ones. If you are a well manufacturer, this casing is something that you will need for sure. So make sure that you understand everything and anything about it.
