Abstract
A flexible liner system provides for instrumentation and sampling within a cavity. An elongated flexible liner effectively contacts wall portions of the cavity when inflated within the cavity and has a top and a bottom and has perforations open to the cavity wall portions at selected locations along the liner. At least one sleeve is sealed to the flexible liner and extends from the top portion of the liner to a perforation at one of the selected locations along the liner to define a sealed interior open to a cavity wall portion. A well casing may be place within the sleeve for fluid sampling or for emplacing instrumentation adjacent the perforations in the flexible liner.
