Comparison of averaging methods for velocity model building from well logs
Autor: Mércia B. C. Silva, Alexey Stovas
Publikováno v: Journal of Geophysics and Engineering. 6:172-176
Using high frequency sonic log data, we compare velocity estimation methods that use either two or three Taylor series terms (linear and quadratic models) to estimate velocity versus depth. Then we verify which method is more accurate with respect to

Correspondence between the low- and high-frequency limits for anisotropic parameters in a layered medium
Autor: Mércia B. C. Silva, Alexey Stovas
Publikováno v: GEOPHYSICS. 74:WA25-WA33
Wave propagation in a layered medium when the wavelength is much greater than each layer thickness (low frequency) produces a response equivalent to that of wave propagation in an equivalent single-layer medium. This equivalent medium is transversely

Prediction of P-Wave Sonic Logs Via Neural Network and Seismic Trace Inversion: A Comparison
Autor: J.L. Martins, R.V. Santos, Sergio A.B. Fontoura, Mércia B. C. Silva
Publikováno v: All Days.
Abstract A methodology that utilizes neural network (NN) architecture was developed for predicting P-wave sonic logs. Well logs and fundamental attributes of seismic traces along a 2-D, migrated seismic line from Namorado Reservoir (Campos Basin, Bra
