Explore the techniques for detecting water production in wells in this presentation. It emphasizes the fine-tuning of wellbore models and introduces three distinct methods for water detection:

1. Temperature Response Analysis: A qualitative approach involving the comparison of measured wellhead temperatures with modeled temperatures to infer water production.
2. Re-injection Cycle Method: This method leverages liquid fallback and re-injection cycles in gas wells to detect water production and calculate water yield.
3. Flash Calculation: Utilizes pressure changes upon well shut-in to perform calculations that estimate liquid yield.

These methodologies are critical in accurately identifying and managing water production in well operations, thereby enhancing reservoir management and operational efficiency.
