Designing Wells to Optimize Performance and Efficiency—How to Minimize Frictional and Financial Losses

Presented on Thursday, December 1, 2011

There has never been a more critical time to design, operate, and maintain groundwater production wells in the most cost efficient manner possible. The primary goal of most well designers is to construct a well that produces the desired amount of water with as little sand as possible. For gravel envelope wells, the desire to limit sand production can often lead to selection of finer filter packs and screen slot sizes than are truly necessary. When this occurs, the success of sand control is often at the expense of well efficiency. The goal of this workshop is to provide attendees with an understanding of the critical components of the well design process that can maximize its production capability with the minimal losses. In minimizing the well losses, the well owner can operate the well with greater cost efficiency.
