Abstract: A system for communicating with underground fluids at different depths or along different lengths (i.e. in a horizontal fashion for SVE) in a common well which includes a plurality of connectable intersleeved casing sections that have apertures which can be manipulated to be open or closed. The intersleeved casing sections include outer sleeve members and an inner sleeve member which is movable with respect to the outer sleeve member. Movement of the inner sleeve member causes apertures therein to align with corresponding apertures in the outer sleeve member. The intersleeved casing sections are connected together by coupling members. Manipulation and opening of a selected intersleeved casing section from a plurality of coupled intersleeved casing sections which form a multi-screen casing allow fluids to be sampled, monitored, tested, remediated, removed or dispensed at a specific depth in a well.
