The Cement Plug Blog

Did you know that there might be a cost difference at nearly 300.000 USD between selecting the least cost efficient technology for setting one single off-bottom cement plug, compared to the most cost effective choice? That is equivalent to a 50-60 percent cost reduction. How is that possible?

Plugging oil wells is a very common operation. Certain tasks regarding cement plugs are considered being straightforward, but setting cement plugs off-bottom is more of a challenge and a costly one too.

How can you save time and money by setting successful balanced cement plugs at first attempt?

When a cement plug is placed off-bottom in a wellbore, it is quite common that it is not found where it is expected. But even if it is, the cement plug is often too soft or fails to provide hydraulic seal. Normally, this is due to contamination of the cement - aka 'green cement'.

How can you avoid this cause for cement plug failure in the first place?

To set balanced off-bottom cement plugs can be one of the most unpredictable and time consuming operations in drilling and P&A. Setting these kind of cement plugs also represent a considerable cost component.

How do you measure the success rate for your cement plugs?
