Info

SUMMARY • The efficiency of the well should be considered during initial planning and design • Designing efficient wells requires minimizing well losses and understanding the relationship between the aquifer, filter pack and well screen • Achieve full production potential of the well by ensuring that it has been fully developed • Monitor the specific capacity and efficiency of the well to minimize operational costs
