1. A continuous and automatic computer implemented method for analyzing fluids from boreholes in near real time for a geothermal, hydrocarbon, or testing well, using a well fluid processor and communicating the analyzed fluid information to at least one client device using a network, comprising:

  • a. connecting a total hydrocarbon analyzer to a wellbore to receive wellbore fluid samples and produce positive pressure fluid samples, connecting the total hydrocarbon analyzer to electronically communicate with the network, performing fluid analysis using the total hydrocarbon analyzer on the wellbore fluid samples forming total hydrocarbon analyzer fluid testing data;

    b. receiving the formed total hydrocarbon analyzer fluid testing data by the well fluid processor;

    c. connecting a mass spectrometer to the total hydrocarbon analyzer to receive the positive pressure fluid samples and to electronically communicate with the network, the mass spectrometer comprising;

    i. a mass spectrometer processor;

    ii. a mass spectrometer data storage;

    iii. computer instructions to measure a mass to charge ratio of molecular weights for components in the wellbore fluid samples forming mass spectrometer fluid testing data; and

    iv. computer instructions to communicate the mass spectrometer fluid testing data to the well fluid processor;

    d. measuring a mass to charge ratio of molecular weights of components for each positive pressure fluid sample using the mass spectrometer forming the mass spectrometer fluid testing data;

    e. communicating the mass spectrometer fluid testing data to the well fluid processor using the network;

    f. storing the total hydrocarbon analyzer fluid testing data and the mass spectrometer fluid testing data in a well fluid data storage connected to the well fluid processor;

    g. using computer instructions in the well fluid data storage to calculate molecular concentrations of molecular species using measured mass to charge ratios from the mass spectrometer of the positive pressure fluid samples;

    h. using computer instructions in the well fluid data storage to transmit identified molecular species to the at least one client device using the network;

    i. using computer instructions to compute and display well event based observations into the geochemical well log template; and

    j. using computer instructions in the well fluid data storage to edit values of the geochemical surface well log using a pointer and using computer instructions to perform the steps of;

    i. providing a pattern when the pointer connects with a track;

    ii. automatically displaying a selected pattern and a percent value of the selected pattern where the pointer connects with the track;

    iii. automatically changing the percent value of the selected pattern by moving the pointer in the track;

    iv. connecting the pointer to an index of the track; and

    v. inserting the selected pattern by moving the connected pointer along the index.
