Cementing plugs help keep the surrounding clean

2018-01-10 11:37:09

Various operations in the cementing process is essential for a competent cement plug. Placing the cementing centralizer correctly helps reduce nonproductive rig time, minimize wasted material and mitigate the need for additional cementing services.

 

The use of off-center Cementing Plugs on casing maintains a minimum annular space on the low side of a deviated well. This improves the cementing operations wells with hole enlargement problems and also reduces the places where caverns can form largely. The production of too much caverns causes problems for hole cleaning and cementing operations through carbonates or sloughing formations.

 

Conventional Cementing Plug

 

In areas where hole-enlargement is required, those areas are already flowed with both drilling fluid and cement. Since, the centralizer’s continuous annular clearance around the casing allows cement to completely seal around the casing to the borehole wall. It is a well defined thing to say that each centralizer types and properties vary from each other. It is in between the pipe and the top wall of the well. Also, you need to keep an eye during the designing of the cementing process as at many cases it may go wrong and one must be careful.

 

Since there is a continuous 360-degree annular space around cementing plugs which allows cement to completely seal the casing to the borehole wall. This mechanical device helps during casing-running operations; the cement may not flow completely around the pipe in these cavernous sections. When it comes to operations, failure to conduct wellbore cleanups could lead to potential failed completions and also they could cost a lot. Therefore it is suggested to use Cementing Plugs during the operation that will conduct successful wellbore cleanups and safer operations.
