Ground Water Utilization: Study of Methods, with Engineering Analysis

摘要

The objective of the report is to summarize known well-construction techniques for obtaining ground water during military field operations. A considerable number of references on drilling methods and equipment exist in multi-language literature. The literature study shows considerable completed research for developing bottom hole drilling methods. There has been much study on the conventional application of turbodrills in Russia. Considerable efforts have also been spent to improve present drilling tools and systems in order to reduce drilling costs. The review of manufacturer's catalogs, leaflets, descriptive literature, and other printed matter on off-shelf items for the well drilling industry indicates very few radical changes in drilling concepts but a trend of the industry to improve the drilling techniques and well construction.
