Eliminates the need for supplementary pressurization through a manifold at the wellhead which saves time, aggravation, and money.
About
Abstract The Boise State University packer and port system provides a system and methods for sampling, monitoring, or influencing isolated zones within wells, shafts, pits, or other boreholes. More particularly, the invention relates to hydraulically isolating zones within a well, shaft, pit, or other borehole to monitor or influence the conditions therein. Our technology provides a simple and low-cost well zone isolation system that can operate at relatively low wellhead pressures, thus utilizing a non-pressurized wellhead system that provides for measurements to be taken in, samples collected from, and/or fluid(s) pumped into isolated zones within the well. This invention is used to provide targeted water sampling and/or monitoring in new or existing wells with an easily assembled and disassembled system for temporary or permanent use. This device provides increased capacity to measure multiple variables over existing tools. Such targeted sampling and/or monitoring are needed at many sites with contamination or other engineering management issues that require location-specific information in an aquifer.
