1. A method of predicting the geothermal gradient of subterranean strata by determining velocity trends in the strata and comparing same with the velocity trends of formations for which geothermal gradients have previously been determined and plotted on semi-logarithmic paper as a family of curves of velocity trends versus geothermal gradients comprising:

  • a. determining the velocity trend at various depths of a wave propagated through the subterranean strata,b. plotting the velocity trend versus depth on semi-logarithmic paper to generate a curve, andc. comparing the curve obtained with a family of similar curves of known geothermal gradients.
