· Assist with materials selection reviews, including carbon steel, CRA, duplex, elastomers, and non‑metallics.
· Review operating envelopes (temperature, pressure, pH, water chemistry) for corrosion relevance.
Inspection & Integrity Support
· Support inspection planning activities including RBI, inspection scopes, and degradation mechanism reviews.
· Review inspection and monitoring data (UT, corrosion probes, coupons, pigging data).
· Assist with anomaly assessment and fitness‑for‑service inputs under guidance of senior engineers.
Chemical & Fluid Management
· Support evaluation of corrosion inhibitors, scale inhibitors, biocides, and other production chemicals.
· Assist with laboratory testing reviews (corrosion testing, elastomer compatibility, scale tendency).
· Review produced water and injection water chemistry for corrosion and souring risks.
Operational Support
· Provide corrosion review for MOCs, well interventions, tie‑ins, and new projects.
· Support investigations into corrosion‑related failures or excursions.
· Interface with operations, inspection, and materials suppliers as required.
