Pre-design geophysical analysis guides the aperture and spatial sampling requirements to capture sufficient data to image the target.
Describe the external factors affecting your project : Borders, boundaries, bathymetry, tides, currents, exclusion areas, etc.
Any number of vessels can be defined - each having any number of sources and streamers. TesserACT then computes the most cost effective shooting plan.
A full suite of manual and automated hazard avoidance tools is available.
A time and space variant current model (e.g. SeisIntel) can be used to evaluate ... and minimize ... infill acquisition that results from feather mis-matches on adjacent lines.
A suite of tools is available to handle undershoots, deadheading and "boxing-in".
A full suite of coverage analysis tools include fold, offsets, rose plots, waterfall plots, etc.
X axis is bin number Y axis is offset

Seabed data is acquired for many reasons :
Long offsets for full waveform inversion.
Acquisition in heavily obstructed or shallow water areas too dangerous for streamers.
Recording of mode converted shear waves for imaging below gas clouds and reservoir characterization.
Increased repeatability and high Signal to Noise Ratio for 4D.
Whether you are using cables, or any type of node, our TesserACT based workflows ensure that your investment efficiently delivers the technical and business objectives of your Seabed project.
In this example bathymetry is used both for accurate operational modelling and fold coverage estimation.
Parallel, orthogonal and arbitrary geometries are supported. Manual and automated hazard avoidance tools are available.
Standard templates are available for common roll patterns, with a flexible interactive roll editor that can handle more unusual cases!
Fold, minimum offset and maximum offset are available for PP and PS coverage. Display can be filtered based on offsets, azimuths, critical angles etc.
Detailed line level and bin level displays, colored by attribute are available.
This example shows the impact of shooting on line changes.
Full suite of operational analysis, including operational constraints like node battery life.
Node inventory tracking throughout the project (on seabed vs on vessel).
View and interpret source and receiver vessel utilization rates.
As acquired data can be compared with planned acquisition, and estimated time to complete can be continuously updated.

Towed streamers are the most cost effective way to acquire short (<12km) offset p-wave seismic data in open water.
Nodes can deliver ultra high Signal to Noise ratio long offset p and s wave data in challenging shallow water and heavily obstructed areas.
Many operators are now using both techniques to deliver smart hybrid solutions.
Sparse node grids can be used to define an improved velocity field through Full Wave form Inversion. Streamer and node data can be acquired simultaneously or independently.
Nodes can be used to undershoot obstructed areas using shots from a simultaneously acquired streamer survey.
Short streamers towed behind an OBN shooting vessel can deliver short offset data, eliminating the need for dense, expensive nodes.
