In general , wells partially penetrate the entire thickness of the aquifer If the length of water entry (or the screen interval) in a well is less than the entire thickness of the aquifer , the well is called partially penetrating well The influence of partial penetration of a well becomes less pronounced as the ratio between the screen interval and the aquifer thickness increases The groundwater flow to or from a partially penetrating well is three dimensional As a result , the drawdown around pumping and observation wells is dependant on their screened lengths and location along the thickness of the aquifer A few number of computer programs appears to provide solutions for partially penetrating well , but , none of these programs deals with all equations of fully / partially penetrating wells , for all kinds of aquifers , and for all flow conditions Moreover , the free access programs are extremely limited
