Abstract | A pump test was conducted in the Dakota Sandstone at Wall, South Dakota, on October 7, 1972. Two observation wells responded to the pumping, and an average value of permeability was calculated to be 9.42 gpd/sq ft. No deviation from the Theis type curve was observed during the 44 hours of pumping at 120 gpm. A pump test was conducted on a new well at Box Elder, South Dakota, on July 6, 1972. The well was pumped at 110 gpm for 54 hours and the recovery was documented. The resulting calculation of permeability is 7.06 gpd/sq ft. (Author) |
