Major Dewatering Techniques PRD Rigs

The eductor well method (also known as ejector wells) is a specialist dewatering method used to control pore water pressures in low permeability materials such as silts or fissured clays. The method operates on the venturi principle, whereby circulation of high-pressure water through eductors in the base of each well creates a vacuum which promotes drainage of low permeability strata. Every
