• Chemical Company was using one chemical with same treat rate (ppm) for all wells: • 10 bwpd or • 2400 bwpd
• Producer was not supplying production data to Chemical Company

DOWNHOLE TEMPERATURE ISSUE
• ESP – Electrical Submersible Pump
• Downhole Chemistry Rated (200 Deg) – No Issues
• Installed ESP – Downhole Corrosion/Scale “paraffin like substance” – seized the ESP • Chemical overheated due to ESP Downhole
Temperature (275 Deg) • Switched to chemical rated at 325 Deg
• Pipeline Spec 4 ppm at Sales Meter Run
• 99 H2S Scavenger pumps
• $300K/YR Scavenger
• No fully defined Pipeline Spec
• 200 H2S Scavenger pumps
• $700K/YR Scavenger

2016: Turned OFF all scavenger pumps under new ownership
• Biocide Treatments • Pipeline Specifications ( ? ppm) • Atomizers vs Drip • Injection points
• Increased Retention Time in Pipeline • Correct usage of H2S Analyzer Tubes • Follow up after Biocide treat, Frac Activity slows, etc
