  • Land, Marine, Seabed & Mixed Mode Surveys

    ACTeQ provides TesserACT 3D survey design software to the world’s leading E&P companies, geophysical service providers and consulting companies.

    TesserACT is a powerful integrated survey design package for land, marine, seabed and mixed mode projects.

  • Better Imaging

    The best image requires
    the best technology,
    the best people
    … and careful planning.

    TesserACT allows you to get the most out of your acquisition and processing technology by ensuring that you focus your effort on the most critical targets.

  • Faster Delivery

    Good planning is the key to fast, reliable project execution.


    • Minimizes the time to acquire
    • Reduces the risk of acquisition surprises that can disrupt E&P development schedules
    • Enables rapid response to unexpected events
  • Reduced Cost

    TesserACT enables effective cost/quality decision making.

    Reliable and easily available image quality and operational cost metrics ensure that your 3D survey is the best possible investment to exploit your sub-surface resources.

ACTeQ is the only full service supplier of 3D seismic survey planning and operational analysis software for land, marine and seabed applications, that is not affilliated with a major geophysical service provider.

What we do...

ACTeQ provides game changing 3D seismic survey design software and innovative, experienced personnel. Our mission is to enable E&P companies and service providers to collaborate in the design of 3D surveys delivering increased return on investment.

3D seismic surveys have become the most important exploration and production tool for oil and gas companies. The last 20 years have seen an explosion in acquisition and processing technology available for land, marine and transition zone surveys:

Slip sweep
Smart phones
Sim source
5D interpolation
Pre-stack migration
Compressive sensing
Marine vibrators
Imaging with multiples
Smart phones
Survey design has not kept pace with the rate of innovation in acquisition and processing …. Until now. TesserACT software from ACTeQ ensures that you get the most from your investment in the latest acquisition and processing technologies for land, marine, transition zone and mixed mode surveys.

Major product announcements at SEG 2019 !

  • Current modelling and infill minimization for marine streamer

  • Illuminations studies and VOI analysis in partnership with Z-Terra

We will be demonstrating TesserACT on the Lenovo stand #1642, with public presentations at Noon each day plus a special Happy Hour presentation at 16:30 on Monday.

“TesserACT: Advanced survey planning for land, marine streamer, seabed and mixed mode acquisition”

In this talk, we will feature a number of survey design optimization projects on-shore and offshore, including our unique OBN scenario optimization capability for cabled systems, ROV nodes, nodes on a rope and flying nodes, as well as integrated seabed and towed streamer operations. We will also be making a major product announcement that will be of great interest to anyone seeking to minimize towed streamer 3D infill shooting.

ACTeQ sponsors successful SEG/GSH Web Symposium on Survey Design

The GSH Web Symposium on Survey Design (New Tools for New Challenges) held on May 29th 2019 was a first of a kind event that brought presentations from 8 industry thought leaders to a global geophysical audience. This format aids the dissemination of ideas by making the latest ideas available at low cost, and with no travel expense. The proceedings were recorded and are available through the GSH.

ACTeQ would like to thank the organisers, speakers and chairpersons for their efforts in making this event a big success.

ACTeQ founder and advisor Dave Ridyard provided a short article for the May GSH Journal to set the background for the web symposium. The article reviews 30 years of history (and in one case 1,000 years of history) to identify broader themes that remain relevant today.

We are hiring !

Survey Design in the Real World

A series of short articles addressing key topics in the arena of 3D survey design; Geophysics, operations optimization and TesserACT tips and tricks

TesserACT tools for compressive sensing

Compressive sensing is emerging as a powerful tool in the geophysicist's toolkit. TesserACT now offers a range of powerful tools to support randomization.

Survey Design for Full Waveform Imaging

Great imaging requires great data. In this short note, Dave Monk discusses one of the key factors that should be considered when designing a survey for FWI.

Image above : This Full Waveform Inversion shows 100Hz data from 300m to 4,500m. The image was produced by DownUnder Geosolutions. Capreolus data is shown by kind permission of Polarcus.
