The process of determining the fluid compatibility (FC) of elastomers and how compatibility affects material selection for downhole applications. Effects of completion fluids (Bromides and Formates) on elastomers. Elastomer samples were conditioned at temperatures from 175°F (80°C) to 380°F (193°C) for up to 3 weeks.
A corrosion cracking assessment evaluated a 13Cr-5Ni-2Mo 110 ksi grade martensitic stainless steel as a potential well tubing material for oil and gas production from Gulf of Mexico reservoirs. Also, Stress Corrosion Cracking at low H2S/low temp/high acidity (pH<3.5) was tested by Cyclic Slow Strain Rate.
