Advances in Well Development
The most important aspect of good well construction is well development. Proper well development will restore the formation damage caused by all drilling process and crate wells that have a long service life, are problem free and a good value for the well owner. The application of multiple development techniques is generally required to fully develop a well. Energy must be directed into the formation through the filter pack and back out of the well to achieve proper well development. Wells that are not fully developed often have problems with sand pumping and biofouling, both of which can reduce well life and create added expense for the well owner. In some bedrock aquifers well yield can be enhanced using well stimulation methods such as hydrofracturing or acidization to open up fractures. Even the best well design cannot achieve maximum efficiency and trouble free operation unless the well is properly developed to allow water to enter the well in an efficient manner.
Thom Hanna, RPG, Johnson Screen Thom Hanna, RPG - Summary of Experience Thom Hanna is employed as District Manager for Johnson Screens where he works in areas of well design, construction and development. He received his Bachelor of Science from Michigan State University and Master of Science from Western Michigan University. Before working for Johnson Screens he worked over 15 years as a hydrogeologist for several ground-water consulting firms including Hydrologic Consultants, Inc., Papadopulos Associates, and Golder Associates. His experiences include hydrogeologic investigations, design and optimization of well efficiencies for mine dewatering and water supply investigations.
