  • Patent number: 9366118
    Abstract: Systems and processes are provided for removing fluid from a subterranean well and enhancing the production of oil and/or gas are herein disclosed. In one embodiment, the system includes an injection conduit, an injection valve, a relief valve, a container, a container valve, a return conduit valve, and a return conduit, all arranged within a subterranean well for removing at least one fluid from the well. The removal of at least one fluid from the well is controlled by the flow of gas into the injection conduit.

  • Patent number: 9200509
    Abstract: The present invention discloses an improved system for measurement of the liquid flow rate and totalized liquid production of a producing well. In the method of the present invention, liquid production rate in a pumping well is determined by calculation based upon wellbore geometry and continuously monitoring the depth of the fluid level within the wellbore. It is applicable to any pump lifted well where it is possible to shut the pump off periodically. Accuracy is enhanced with this method by properly accounting for pump leakage and where pump leakage is either known or can be estimated within reasonable limits or where it is measured during the pump shut off cycle.
