TesserACT Software
Functions

TesserACT provides an easy to use, single environment package for all your geophysical survey design and operational optimization needs.

NEW : Z-Design : 3D Ray Tracing Module for TesserACT

Z-Design is the result of a collaboration with Houston based Z-Terra Inc. Seamlessly integrated into TesserACT, Z-Design delivers fast, robust, interactive 3D ray tracing and visualization to TesserACT users. Features such as automated aperture calculation allow TesserACT users to deliver cost effective and rigorous survey designs in far less time than competing systems. 

View Survey Design Express #16 to see how Z-Design can be used to optimize survey aperture.

Compressive Sensing (CS)

Through our collaboration with In-Depth, TesserACT now includes full support for survey designs using CS. Compressive sensing takes advantage of modern wavefield reconstruction techniques to deliver increased resolution and lower cost. Mutual coherency maps provide  quality control of the effectiveness of the survey design. 

Please contact ACTeQ for additional information.

Pre-design geophysics

TesserACT's pre-design geophysics tools ensure that your survey design has the right aperture and spatial sampling to deliver the image you need at the minimum cost.

Modelling

The TesserACT base product has limited modeling capability (dipping layer cake model with a constant velocity gradient).

Z-Design is a TesserACT module that delivers full 3D ray tracing functionality.

For the most challenging projects, ACTeQ has partnered with Z-Terra to offer wave equation based  illumination studies.

TesserACT also offers a direct connection to NORSAR's modelling software.

Wizard based geometry creation

TesserACT's wizard based user interface makes it easy to generate even the most complicated survey geometry. Complex roll patterns and variable density shots and receivers are a snap !

Optimization

TesserACT combines a sophisticated route optimization algorithm with detailed operational modeling to deliver the lowest cost solution to any operational challenge.

In marine applications, we employ a time and space variant current model to minimize in-fill shooting.

Weighted Path Optimization

A set of user defined constraints and weights allow automated survey design that achieves the desired balance between cost, environmental impact and geophysical requirements.

See November 2022 "Leading Edge" article by Dean et al.

Coverage analysis

TesserACT supports rigorous binning combing new and legacy coverage from any form of acquisition : towed streamer, seabed nodes, seabed cables, floating nodes, borehole etc. Traditional PP and PS and Fresnel Zone binning are supported. 

Detailed bin, line and 3D displays are available

Emissions and fuel consumption estimation 

TesserACT can now estimate fuel consumption and greenhouse gas emissions for marine geophysical surveys based on the EnerGeoAlliance  “Guidance for Estimating and Reporting Greenhouse Gas (GHG) Emissions”. Estimates are based on information such as the drag associated with towed equipment and variations in ocean and tidal current. These tools allow a user to compare the emissions and fuel consumption for multiple candidate survey designs.
