Receiver Function Inversion Using Genetic Algorithms
We use a genetic algorithm to attack the receiver function inversion problem where the objective is to retrieve shear wave velocities of rock layers as a function of depth. The receiver function inversion is a non–linear, multi–modal, and multi–parameter optimization problem suited for genetic algorithms. We implement a three operator genetic algorithm consisting of selection, single–point cros...

متن کاملBroadband Geo Acoustic Inversion from Sparse Data Using Genetic Algorithms
Matched eld acoustic inversion techniques were investigated using data from sparsely populated vertical receiving arrays and a single receiver element The purpose of considering sparse data sets is to investigate under simulation the feasibility of reducing the number and complexity of acoustic measurements needed for geo acoustic inversion The entire bandwidth of the Geo Acoustic Inversion Wor...
متن کاملInversion for seismic anisotropy using genetic algorithms 1
A general inversion scheme based on a genetic algorithm is developed to invert seismic observations for anisotropic parameters. The technique is applied to the inversion of shear-wave observations from two azimuthal VW data sets from the Conoco test site in Oklahoma. Horizontal polarizations and time-delays are inverted for hexagonal and orthorhombic symmetries. The model solutions are consiste...
متن کاملGenetic Algorithms for Seismic Travel-Time Inversion
This paper attacks the problem of seismic travel-time inversion using genetic algorithms. Seismic surveying is usually a precondition to engineering and construction work in an area and travel-time inversion is a method of deducing sub-surface features from the measured travel-times of seismic waves. We consider both the one-dimensional and two-dimensional versions of the problem and explore di...
