1. A method for generating at a first location a visual display corresponding to well logging data present at a second location, comprising:

  • (a) generating a digital initialization data block at said second location;

    (b) transmitting said data block to said first location;

    (c) storing said data block at said first location;

    (d) generating at said second location a digital representation of a first value of said logging data derived at a first depth within a borehole;

    (e) transmitting said digital representation to said first location;

    (f) storing said digital representation at said first location;

    (g) deriving at said first location from said stored data block a first set of digital numbers corresponding to first positions on said display;

    (h) deriving at said first location from said stored digital representation of aid logging data second set of digital numbers corresponding to second positions on said display;

    (i) displaying at said first location visual representations of said first and second sets of digital numbers at respective said first and second positions on said display;

    (j) generating at said second location a digital representation of a delta data value corresponding to the difference between said first value of logging data derived at said first depth and a second value of said logging data derived at a second depth within said borehole;

    (k) transmitting said digital representation of said delta value to said first location;

    (1) storing said digital representation of said delta value at said first location;

    (m) deriving at said first location from said stored data block a third set of digital numbers corresponding to third positions on said display;

    (n) deriving at said first location from said stored first value of said logging data and said delta data value a fourth set of digital numbers corresponding to fourth positions on said display; and

    (o) displaying at said first location visual representation of said third and fourth sets of digital numbers at respective said third and fourth positions on said display.
