Analysis on water conductivity of fault based on pumping test and dewatering test
Meikuang Anquan, 2022 In order to avoid the water disaster of fault and sandstone below the coal seam, it is necessary to master the conductivity of fault accurately. Through the dewatering test with large drawdown and water flow of Baotashan sandstone aquifer in the bottom ...

Software for Evaluating Pumping Tests on Real Wells
Applied Sciences, 2021 As the climate is changing, greater exploitation of groundwater reserves is becoming evident; however, this would have been apparent even without climate change. Therefore, increasing emphasis is given to maintaining well functionality.

Geophysical Journal International, 2006 SUMMARY We performed pumping tests with a periodic succession of injection and production intervals in a field of three shallow boreholes penetrating a jointed sandstone formation. Tests were conducted at periods ranging from 10 to 5400 s and pumping rates between 5 and 20 l min−1.

Formulating surrogate pumping test data sets to assess aquifer hydraulic conductivity
Journal of Hydrology X, 2018 A hypothesis to estimate hydraulic conductivity from surrogate pumping tests formulated using routinely monitored pumping rates and hydraulic heads is tested. The data set of a surrogate pumping test contains only a few late-time drawdowns represented by
