ABSTRACT
If well performance-degrading problems such as sand pumping, corrosion, or biofouling are detected by monitoring, then what? At this point, preventive maintenance repairs and treatment are implemented. Preventive treatments must be implemented upon detection of the indicator signs of a problem and before performance deteriorates. The nature of the response or treatment depends on the nature of the problem. The decision-making process might follow the decision flow paths illustrated in Figure 6.1. To make such plans effectively, well systems must be equipped for preventive monitoring and treatment (Chapters 4 and 5) and a maintenance program must be in place (Chapter 5 and 6).
