(HP67) Exploration Geophysics Calculator Programs:
The ABSTRACT from Exploration geophysics calculator programs for use on HewlettPackard models 67 and 97 programmable calculators by David L. Campbell and Raymond D. Watts (US Geological Survey), OpenFile Report 78815 (1978), 75 pages.
Program listing, instructions, and example problems are given for 12 programs for the interpretation of geophysical data, for use on HewlettPackard models 67 and 97 programmable handheld calculators. These are … (1) gravity anomaly over 2D prism with ≤ 9 verticesTalwani method; (2) magnetic anomaly (ΔT, ΔV, or ΔH) over 2D prism with ≤ 8 verticesTalwani method; (3) totalfield magnetic anomaly profile over thick sheet/thin dike; (4) single dipping seismic refractor interpretation and design; (5) ≤ 4 dipping seismic refractorsinterpretation; (6) ≤ 4 dipping seismic refractorsdesign; (7) vertical electrical sounding over ≤ 10 horizontal layersSchlumberger or Wenner forward calculation; (8) vertical electric sounding: Dar Zarrouk calculations; (9) magnetotelluric planewave apparent conductivity and phase angle over ≤ 9 horizontal layersforward calculation; (10) petrophysics: a.c, electrical parameters; (11) petrophysics: elastic constants; (12) digital convolution with ≤ 10length filter. reformat for readability, mine BEST!
