For those in the down hole oil and gas industry, we should be pretty familiar with NACE MR0175 and its requirements. Unfortunately I have never really had the privilege of being an understudy to someone who really knows what he/she are talking about and because of this I have a few questions:
1. Where can I learn about the effects of H2S and CO2 on alloy and stainless steels (website, courses, books etc.)?
2. Customers frequently present well bore conditions and ask if "such and such" material is suitable for the environment. This ties back to my first question about where to educate myself. There seems to be a lot of factors at play (CO2 levels, H2S levels, wet/dry gas, temp, pressure etc.) and I haven't happened to find documentation to help determine the appropriate responses.
I have worked as a valve engineer (API 6A) and standards have been developed for parts (gate, seats, stems, bonnets etc) for certain environmental conditions, but these charts do not explain why the materials were chosen.
Appreciate any help in advance.
