Seismic Signal Processing TRIZ Cases

Grouping microseismic events resolves the ambiguity of indistinguishable nodal planes in moment tensor inversion, enabling precise fault plane determination.

Variable length spatial filtering adapts to frequency bands, preserving signal energy while attenuating low-frequency marine noise.

Adapts noise templates using complex-valued directional multi-resolution transforms to reduce marine survey data interference.

Analyzes multiple offset and angle stacks to identify geologic features, resolving incomplete interpretations from single-volume data.

A physical seismic simulation test apparatus generates artificial hydrate models using cryogenic and pressure controls to emit ultrasonic waves.

A modified Hoek-Brown failure criterion incorporates intermediate principal stress to predict rock shear behavior.

A double-searching apparatus determines anisotropic parameters using exhaustive grid search and global optimization.

A cross-correlation least-squares reverse-time migration method optimizes seismic reflectivity models using correlation metrics.

Iterative basis function selection represents seismic signals with minimal residual error at measurement locations.

A seismic full horizon tracking method segments three-dimensional data into overlapping subspaces for independent clustering of horizon extreme points.

Curvelet domain denoising method separates signal from noise in seismic datasets.
