ABSTRACT:
A method and apparatus for measuring the draw down of a water well by making in situ measurements of the static and dynamic water table levels. A well bore located pressure sensor provides the hydrostatic pressures to a surface located electronic measuring unit which provides a draw down measurement directly in terms of feet of water. An extension of the method provides for combining the measured draw down parameter with water discharge pressure and water flow measurements to derive a set of data which uniquely characterizes the production capability of the well. The apparatus performs all measurements automatically and has provisions for producing a time history of the well parameters, and telemetering to a central station for monitoring and processing.
