Permian Basin, Texas:
• H₂S content: Up to 10% in certain wells
• Impact:
Production loss: Estimated 20-30% reduction in well productivity due to formation plugging and equipment corrosion, translating to lost revenue exceeding $50 million annually. This calculation assumes an average well production of 1,000 barrels per day and a crude oil price of $50 per barrel.
Corrosion costs: Approximately $10 million annually for replacing damaged pipelines, valves, and other equipment, as reported in the SPE paper.
Bakken Formation, North Dakota:
• H₂S content: 3-5% on average, with pockets exceeding 10%
• Impact:
Production loss: A 15% decline in overall field production over a two-year period, resulting in lost revenue of roughly $150 million. This estimation considers the field’s average production of 50,000 barrels per day and a $50 per barrel price point.
Corrosion costs: NDMNR reports indicate company spending $20 million on infrastructure repairs and replacements attributed to H₂S corrosion within the Parshall Field.
Eagle Ford Shale, Texas:
• H₂S content: 2-4% on average, with localized spikes up to 8%
• Impact:
Production loss: Well shutdowns and reduced flow due to H₂S plugging resulted in a 10% production decline across the field, leading to lost revenue of approximately $40 million. This calculation is based on the field’s average production of 20,000 barrels per day and a $60 per barrel price.
Swimming Pools
School Pool
The positives for them are the following:
1. Clarity of Water
2. Kids saying their eyes don’t burn
3. Can’t smell chlorine at all in the building
4. The covers that were white from Chlorine are now self cleaned
5. Gas use for pool heating reduced R24,000 p.m.
6. Pool specialist not required, R6,500 p.m.
7. Chemicals savings R5,600 p.m.
8. Total savings R36,100 p.m.
This saving doesn’t consider reduced backwash cycle, fliter cycle, saving on electricity and water
