Interrelationship of Resistivity and Velocity Logs,meters shows that depth, lithology and age are not as specifically related to velocities as are the physical parameters of density, elastic constants, pressure, temperature and porosity. The Nafe and Drake curves relating velocity to density and porosity are seen as the most effective theoretical—em

Focused Resistivity Logs,he unfocused normal and lateral sondes—against highly resistive thin formations. These large deflections, however, do not signify any inherent superiority of these tools, but are the result of using a set of fictitious and genetically unrelated currents in the apparent resistivity formulae—currents

Acoustic Logging: The Complete Waveform and its Interpretation,. Four components of the wavetrain, viz. shear and compressional lateral waves, the Stoneley and pseudo-Rayleigh waves, are discussed. A description of experimental studies of the acoustic wavetrain in homogeneous and inhomogeneous scale models is given followed by analytical results pertaining to e

Electrical Anisotropy: Its Effect on Well Logs,ed where anisotropy can lead to some ambiguity in the interpretation of the measurements. Other tools are considered that are designed to be sensitive to anisotropy and yield a measurement of it. Our conclusions appear as the effects of anisotropy on standard logging tools and a proposal for a new t

Borehole Geophysics in Geothermal Exploration,le geophysics as applied to petroleum exploration. The chief differences between these applications are in the temperatures and in the unique lithology of geothermal reservoir rocks. Equipment that will make logs dependably at temperatures greater than 200°C is not widely available, and the interpre
