8.9 Summary

Selection of the appropriate drilling process requires an understanding of the geology and the objectives of the project. Rig safety and getting along with the drilling contractor can be done in a cooperative environment if the hydrogeologist shows common courtesy and common sense. Well construction and development requires that accurate samples be collected in the production zone. If it is a monitoring well, then the construction materials need to be resistant to the contaminants involved. For production wells, a sieve analysis, screen design, and development strategy can be chosen that effectively produces a maximum yield.
