I have a 25m confined aquifer of transmissivity of 4.85*10^-3 m2/s. Pumping has been occuring for a long time at a constant 0.05m3/s. 3 meters away in an observation well there is a 3m drawdown. How can I calculate the expected drawdown in a well 300 meters away? Any ideas?

Refer to the following publication - it'll have all the equations you need for fully or partially penetrating wells in artesian aquifers. You will likely need to determine the value "R", which is the radius to zero drawdown. You can relate "R" to hydraulic conductivity using the formula shown in the book.
