abstract = "Based on the Multigene genetic programming (MGGP)
method, the static elastic moduli (Young's moduli) of
reservoir sandstones are estimated with the bulk
densities, porosities and P-wave velocities data. A
analytical expression for static moduli is obtained by
evolution according to the method, and the static
moduli are calculated by the expression. Then the
calculation results are compared with those obtained by
experimental and empirical methods. It shows that MGGP
method is more accurate than the traditional empirical
relation between dynamic and static parameters.
Furthermore, MGGP requires less input parameters. For
example, S-wave velocities are not necessary. So the
method reduce the error induced by the inaccurate or
missing of S-wave velocities.",
