Why are cased-hole centralizers so important in the oil and gas industry?

When you pump your gas, do you ever think of all the steps it took to get to your car?

Unless you are working in the oil field, most of us are simply happy to know we can purchase gas for our vehicles easily by driving to a gas station and grabbing the pump.

Do you ever consider the different types of equipment and teamwork it takes to safely and successfully extract oil from a wellbore? If your answer involves an eyebrow raise and saying, “Not really,” you would be in the majority.

But what if the equipment did not exist? Every piece has its role and one wellbore tool that holds importance is a cased-hole centralizer.

The basic function of this tool is to make sure that as logging tools go down the casing of the wellbore, it is even on all sides from the inside of the casing. They keep everything uniform and ensure efficiency of cased-hole logging down into the well. 

But why is this important? 

While this type of logging is performed more rarely, it still provides valuable information about the well. One important function of cased-hole logging is when the well may have already started production but has begun to experience reduced flow. With the help of a cased-hole centralizer, this type of logging could help determine what has hampered flow. 

Using this specific centralizer provides more accurate movement into the wellbore so logging can take place and companies can decide their next move. In some cases, the decision may be made to recomplete the well or even abandon the well.

So as you patiently wait for your car to fill up and you watch the tick of the gallons rise, give a little nod to the importance of the cased-hole centralizer and its role in keeping your wheels rolling.
