Corrosion Will Occur, Whether You Like It or Not

Just like Houston’s summer heat, corrosion of metal surfaces will occur—whether you like it or not. To help you better understand corrosion, these papers describe using water surveys in a production/injection plant, testing the effectiveness of mitigation, and data evaluation using machine learning.

There are certain things in life that will happen, whether we like it or not. As I write this introduction it is early September in Texas and it still feels like summer—triple-digit hot. That is just the way it is, whether I like it or not, and to be perfectly honest, I don't. Obviously I could move to a place with a more moderate climate, but instead I rely on air conditioning whenever the weather forecast tells me that it is going to be hot.

In our professional lives as engineers working on oil and gas facilities, there are definite parallels: things that tend to happen whether we like it or not. An example is the corrosion of metal surfaces. We need surveys to find out what kind of corrosion rates we can expect (the equivalent of the weather forecast), and then, if necessary, take mitigating actions, whether through material selection or the use of corrosion inhibitors and biocides (the equivalent of the air conditioning). Obviously, we try to work on different types of facilities, but just as we always have to deal with the weather, so, too, do we have to deal with corrosion.

This is why I selected four papers on corrosion. One deals with a survey (more specifically, a water survey for effective souring and corrosion management in a production/injection plant) and two deal with testing the effectiveness of mitigating actions (the use of HDPE liners and various biocides). The latter goes back to surveying, but focuses on how to evaluate the information obtained through machine learning—a very appropriate topic in this day and age when we work with big data.

I encourage you to read one or more of these papers to better understand the various aspects associated with corrosion.

Because corrosion is one of those things that will happen, whether you like it or not.
