Effects of H2S on BeCu
Effects of H2S on BeCu
(OP)
I am looking for anyone that can help with the specific effects that H2S would have on BeCu in an oilfield drilling application. Thank you

RE: Effects of H2S on BeCu
The BeCu is used in the construction of tool housings for Directional Drilling MWD Downhole Steering tools. They are tubular housings approx .250" in thickness. Exposure to H2S timeframe is varied from several hours to several days. The temperature ranges from 80-125C with downhole pressure ranging from 500-5000 PSI. Unfortunately the concentration of H2S also varies greatly during the driling process.
What I was looking for was an explanation of how H2S effects and causes damage to BeCu. How it changes the properties of the alloy and what overall damage could be expected. We had some tools recently that were exposed to H2S during drilling operations and an explanation to go with the physical apperance is what I was hoping for.

In order to protect against this type of failure mechanism, oxygen free BeCu should be specified.
