Abstract:
1. A method for monitoring and optimizing fluid extraction from geological strata comprising: modification of a check valve, said check valve including a flap element, such that the modification further comprises the sequential steps of removing the check valve, locating the flap element, attaching a magnet to the flap element, and reinserting the check value, such that the magnetic field is detectable by a flow transducer; coupling the flow transducer to the check valve operatively coupled to a discharge conduit associated with a walking beam type pumping unit, wherein said flow transducer is adapted to generate flow signals by detecting movement of a sensing element associated with said check valve, electromagnetically coupling said flow transducer to a local processing system, monitoring said sensing element and said flow signals at least during operation of said walking beam type pumping unit, A/D conversion of said flow signals by a sensing element to create flow signal data; accumulating a portion of the flow signal data in a memory associated with said local processing system, and determining an optimum pumping cycle from said accumulated flow signal data, wherein said optimum pumping cycle eliminates fluid pound.
