Introduction
You might think your reservoir is stable, but changes in injection water or microbial activity can lead to souring—and H2S is no joke.

What is Reservoir Souring?
It’s the production of hydrogen sulfide (H2S) by sulfate-reducing bacteria due to injected seawater or nutrient changes.

The Impact

• H2S is toxic and corrosive
• Increases operational costs
• Raises health and safety risks

How Evasil Predicts Souring
We conduct souring simulations, H2S modelling, and microbial profiling to forecast and mitigate issues.

Prevention Tactics

• Biocide treatment optimization
• Nutrient limitation in injected water
• Advanced monitoring of reservoir conditions
