Abstract

One of the problems associated with long term use of wells is creation of deposits on well screen or gravel packs. The deposits, despite the presence of water in the context of the aquifer, prevent the penetration of water into the well. As a result, it greatly reduces the amount of water production of the well. Rehabilitation of wells is characterized by removing the deposits from the front and back of the well screen. So far, there have been some methods of well rehabilitation, nowadays, however, with the development of technology, more efficient methods have been developed causing less damage to the aquifer and the environment. In this study, new methods of well rehabilitation are investigated for implementation in Iran. A criterion for determining the efficiency of the methods is proposed. The method of air shock in combination to water jet is estimated to be more efficient with less time and cost consumption for implementation in Iran.
