Apparatus for compiling and monitoring subterranean well-test data

An apparatus for compiling and monitoring data during testing of a subterranean well connected to a production test system having a plurality of transducers for generating signals representing operational characteristics of the well, including at least one transducer positioned at the surface of the well for generating a surface operational characteristic signal representing at least one of wellhead pressure, wellhead temperature, gas temperature, oil temperature, gas differential pressure, static separator pressure, oil flow and water flow, comprising:

• means for storing values of the transducer signals;
• means for periodically reading the values of the transducer signals into said means for storing;
• means for reading said stored value of said one surface transducer signal to generate a value for an additional operating characteristic of the well;
• means for generating a plurality of output signals representing said stored values and said additional operating characteristic value;
• means for interconnecting the transducers of the production test system, said means for storing, said means for reading, said means for generating said additional operating characteristic value, and said means for generating output signals for intercommunication;
• a power supply connected to power the transducers, means connected to said power supply for generating a voltage level signal representing the magnitude of the power supply output voltage, and means for comparing said voltage level signal with predetermined upper and lower voltage limits to generate a power fluctuation signal when said voltage level signal is outside said voltage limits.
