End to End Seismic Services

Processing Overview

Seismic processing calls for a unique approach to each dataset. Having processed more than 150 hard-rock seismic datasets, our team have developed a unique skillset and wealth of experience to apply to your datasets, both new and old. This includes the application of modern processing techniques such as PreStack Depth Migration, Reverse Time Migration, 5D Interpolation and Full Waveform Inversion, through to emerging workflows and research algorithms.

Advanced Imaging

Our range of advanced imaging workflows are tailored to each dataset and chosen based on what is most suitable to the data. These capabilities include but are not limited to:

  • PreStack Depth Migration (PreSDM)
  • PreStack Time Migration (PreSTM)
  • Reverse Time Migration (RTM)
  • 5D Interpolation
  • Full Waveform Inversion (FWI)
  • Quantitative Interpretation (Litho-Mod)

As seismic data is the foundation of all our Innovation Products, we are committed to producing the highest quality migrated seismic volumes to ensure accurate interpretation and analysis.

RE-VIS Reprocessing

While seismic data has been used for decades, advancements in technology, research, and high-performance computing have revolutionized processing techniques, allowing us to ‘shine new light through old windows.’

HiSeis regularly reprocesses legacy datasets, optimizing them to meet modern exploration goals by enhancing resolution and interpretability at economically viable depths.

Seismic data is constantly evolving—if you haven’t revisited your data in the last 3 years, significant improvements can be made using the latest techniques.

HiSeis also maintains a large catalogue of reprocessed public data. Contact us to see if updated datasets are available near your project

Ambient Noise Tomography (ANT)

Our processing team has the capability to process Passive Seismic data or Ambient Noise Tomography (ANT). As our ANT workflows have been developed from scratch in-house, we have tailored our processing routines to supplement your subsurface knowledge through the inclusion of 2D and 3D shear wave velocity models. These datasets, while lower resolution than our active seismic datasets, can provide 3D context to 2D active seismic programs.

Borehole Logging

Borehole seismic data has been shown to provide a valuable constraint when processing 2D and 3D seismic data as well as a detailed insight into the seismic properties of a geological environment.

HiSeis routinely incorporates borehole seismic processing into the workflow including VSP, Walkway VSP, Full Waveform Sonic and DAS datasets.

Borehole data features heavily in our advanced processing workflows including Full Waveform Inversion (FWI) and PreStack Depth Migration.

HiSeis works actively in 4D VSP processing for.

Distributed Acoustic Sensing (DAS)

HiSeis has experience in processing DAS (Fibre Optic) datasets in both borehole and surface deployments and has been an active player in the research and development of the technique and its application to the seismic industry.

DAS as a seismic receiver enables high density data acquisition with significantly lower source effort, particularly in borehole deployments.

While DAS is yet to see widespread adoption in the mining industry, the technology is extremely promising and opens up a range of applications for seismic monitoring and data acquisition.
