WebSep 6, 2024 · A common measure of well performance (or capacity) is referred to as the “specific capacity” which is defined as the pumping rate (gallons per minute) divided by the drawdown or increased depth to water during pumping (in feet). Generally, a decrease of 25% or more in well yield indicates that rehabilitation is in order. WebBecause wells are not always drilled vertically, there may be two "depths" for every given point in a wellbore: the measured depth (MD)measured along the path of the borehole, and the true vertical depth (TVD), the absolute vertical distance between the datum and the point in the wellbore.
