Seismic Processing

Seismic Processing

  • Our company offers professional seismic data processing services. This involves transforming raw seismic data (recorded during acquisition) into interpretable data volumes (post-stack data). By applying various filters and corrections, such as denoising, deconvolution, interpolation, and velocity estimation, we enhance the signal-to-noise ratio and remove artifacts. We guarantee these key seismic processing deliverables to our esteemed clients:

    Field Data Validation: Ensuring accurate shot and receiver positions, travel time, and reflection points.
  • Noise Removal: Applying filters to enhance signal quality and remove unwanted noise.
  • Deconvolution: Improving seismic wavelet shape.
  • Static Corrections: Addressing near-surface effects due to topography and weathering.
  • Velocity Analysis: Estimating subsurface velocity variations.
  • Migration: Transforming data from time domain to depth domain.
  • Full-Azimuth Processing: Utilizing all available azimuths for better imaging.
  • Anisotropic Imaging: Accounting for subsurface anisotropy.
  • Multiparameter FWI: High-resolution velocity model building.
  • Stacked Sections: Creating interpretable seismic images.
  • Amplitude Variation with Offset (AVO): Quantifying fluid properties.
  • Attribute Analysis: Identifying geological features.
