Where 



V - velocity compressional elastic wave 



K - bulk modulus, or coeff. of incompressibility 



B - compressibility = 1 / K 



p - density 



\x - shear modulus, or modulus of rigidity 



n - porosity, or pore spaces, expressed as a 

 fraction of the total volume 



4. After the compressibility, B , was computed, 



the other elastic properties were computed using the velocity 

 of the compressional wave, V , B , and the density, p. 



The equations favored in these computations were:
