Abstract
We are concerned with the application of the Integral Pumping Test (IPT) method for obtaining mass flow rates at the field scale. The IPT method, first proposed in Teutsch et al. (2000), is based on the interpretation of concentration-time data measured during pumping tests, increasing the observation scale to the size of the well capture zone. Here, we show how the novel non-recursive explicit solution for evaluation of single-well IPTs and the associated analytical framework developed in Bayer-Raich et al. (2004) can be used for the dimensioning of multiple-well IPTs.Keywords
