Well analysis applications for oil and natural gas wells with intermittent flows

A computer-implemented method, comprising:

• displaying, by a computing system, a candidate selection interface for analyzing a candidate well with an intermittent flow and determining whether the candidate well is suitable for installation of a valve for intermittent flow wells, the candidate selection interface comprising fields for at least one of gas liquid rate, wellhead pressure, American Petroleum Institute (API) gravity, depth, choke availability and wellhead connection points, well completion, liquid density, gas density, gas interfacial tension, liquid interfacial tension, gas wellhead pressure, tubing area, surface temperature, and compressibility factor;
• calculating, by the computing system, a lifting gas rate and a critical lifting rate for the candidate well based on the fields of the candidate selection interface;
• responsive to the well being a suitable candidate due to the lifting gas rate exceeding the critical lifting rate for the candidate well, displaying, by the computing system, a valve design module comprising at least one of a basic well data module, a dynamic forecasting module, a valve calibration module, and a reporting module;
• and
• facilitating design of the valve via the valve design module, by the computing system.
