Sour gas, hydrogen sulfide, dissolved in water produces what is known as sour water. This in turn can cause brittleness in the high-strength steel (HSS) used in oil drilling, particularly in deep wells. Sour water is acidic and can be indicated with acid range pH test strips but lead acetate test papers are an inexpensive way of confirming the presence of H2S.

These test papers do not come with a color chart but the presence and relative concentration of hydrogen sulfide is readily apparent. While normally specified with a 5ppm detection sensitivity, 1-3ppm appears to sufficient to slowly cause the white test paper to turn grey.

“Sour drilling environments where H2S gas is present and sour-gas kicks are possible can lead to sulfide stress cracking (SSC) failures in steel drill pipe. In practice, a combination of stress, an environment containing H2S and a susceptible material are required for SSC to occur.”  Excerpt taken from an article in Drilling Contractor: What really happens to high-strength drill pipe after exposure to sour gas environment?

The test strips from Indigo are top notch. They are always competitively priced and shipped on time. The best part of dealing with Indigo is that they stay on top of their products. We had a bad batch of strips arrive in the past but before we could figure it out the hard way, Indigo had identified the issue and had a replacement order already in the mail to us. Pretty hard to beat that kind of customer service.
