...-ky space and masked with the pedestal filters generated from the attribute data. The reverse transform of the masked amplitude data yields modeled noise time or horizons slices that are then adaptively subtracted from the original data to produce filtered seismic data. Finally we unslice the filtered...

... incorporates advantages from two inversion strategies. Magnetic amplitude data are first inverted to recover an effective susceptibility model, providing information about the geometry and extent of the magnetic anomaly. The effective susceptibility model is then used to constrain a Magnetic Vector Inversion...

Jointly inverting the amplitude data with satellite gravity gradiometry data further helps overcome the adverse effect from unknown directions of magnetization. Simultaneously, the amplitude data also helps...

.... In areas with strong remanence and self-demagnetization, the total magnetization can have an orientation different from the induced field direction which precludes the use of traditional inversion methods. To overcome this problem, the magnetic amplitude data that are weakly dependent on the magnetization...

To overcome these challenges, we investigate amplitude error statistics. amplitude...
