How does NeST compare
to current solutions?

All of the described features exist in a single application.

Adaptable to your needs. Organized into distinct panes that can be organized across multiple displays to fit your processing flow and preferences.

No more keeping track of 100's or 1000's of files. Once you import data, NeST handles everything.

All seismic files, GPS, and field notes for each line/acquisition, with all lines organized into a single internal database

Need to collaborate on a project? Export your entire survey, including all data QC, analysis, picks, inversion results, and final results as a SINGLE file. Send this file to a colleague who can import it on their system and pick up wherever you left off.

NeST is built to preserve data integrity at every step. We keep track of all changes, no matter how small, and inform you when a change may change your results.

Check out your SEG head information. Supports .sgy, .segy, .sgd, .segd, .sg2, .seg2, and .dat files

Import and manage DEM datasets. Supports .tif, .img, .adf, and .hgt DEM formats.

Add your field notes or any other text based information into NeST and this information will be saved and maintained within our survey file.

Simple global change to meet you needs (i.e meters or feet)

Give your eyes a break. Choose the mode that gives you the least eyestrain

Continue the glorious 'Ctrl'+'Z' magic in your processing flows when you accidently deleted a bunch of picks

Make your Go-TO acquisition and processing flows truly repeatable, including processing flow templates.

Adapts to your acquistion types. Don't be flooded with a ton of buttons and options that are unrelated to your current acquistion setup.

Reorder all of your traces in any way you need

We will keep track of all your channel maps, to be reused for future projects with the same acquistion setup.

Both Fixed array and Roll along surveys

Define geometries using a handful of simple parameters

Variety of tools (e.g. adaptive table entry tools) to make complex geometry scenarios simple.

Have you already preprocessed your data into a segy file with full and complete geometry headers? We can just import that!

Once GeoReferenced, visualize and navigate through your acquistion using the map

Import GPS data, map these GPS data to sources and/or receiver postions

Use your complete GPS dataset to directly georeference your entire acquistion array, and we will correctly configure all geometry associated values.

Use a potentially more accurate lidar derived DEM and to replace your GPS derived elevations.

Place any and all of you acquistions setups on a map and be correctly georeferenced.

No GPS? No problem! We can take your measured geometry and place in on the map where you need it.

Select a range of shots and simply select 'stack'

You can still view and/or preprocess any of the individual shots within a stack, all without unstacking

Is your geometry for all you prestacked shots already defined? We can auto stack for you with a single click

Out of the box, has a simple predefined set of processing steps for the respective processing type.

Build as complex and interconnected of data flows as you need.

Easily probe/view the result of any single processing step within your process flow

View/probe you data in multiple locations simultaneously with synced multiview

Process the same line multiple times to compare different analyses steps, inversion parameters, or picks from different users.

Clone an analysis, make adjustments or changes to try something else, and generate new results. These separate analyses can then be compared.

Real time updates to your processed data results. No batch running your processing and saving to a bunch of files to then be opened and viewed. We do the processing in real time, as needed.

Intermediate processing steps saved to files to opened and viewed later for continued processing

Did we mention our processing algorithms are FAST? This allows for interactive, real time data processing.

View your processing results every step of the way. Also easily compare and contrast data with different processing steps

Variety of time based data windowing processing steps with interactive setup

Phase shift transform done on multicomponent records to make estimates of surface wave dispersion in the Phase-Velocity vs. Frequency domain

Estimate dispersion images in Phase-Velocity, Wavenumber, and/or Slowness domains, at the same time.

Array deconvolution steps to improve the dispersion image quality

Images include aliasing thresholds to help the user avoid interpretation of artifacts in the images

Corrections made when array is not in a perfectly straight line. Needed when doing seismic land streamer work on winding roads where streamer is not always straight

Click, Drag and Release is all you need to pick!

Pick your dispersion curves in multiple domains (FK, FV, and/or FP)

Set bounds for each mode, and pick them all simultaneous with the press of a key

Use your dispersion curve to estimate a 1D shear wave velocity vs. depth profile

Analyze, pick, and invert with higher modes in addition to the fundamental mode

Layer model setup using an optimized internal algorithm without user input

These include various ways to set layer thicknesses based a different rules.

Set up your initial model however you need for your project

We can leverage a single core, to hundreds of CPU cores for simultaneous inversion steps.

No unnecessary assumptions are used to simplify the forward model or inversion algorithm to make implementation easier. We code it right from the start without assumption based shortcuts.

See how the inversion progressed through iterations

Tells you how sensitive the various model parameters are within the inversion.

Support passive MASW approaches to be used in conjunction with normal linear array active source methods to help increase low frequency coverage.

Create higher spatial resolution 2D velocity profiles from fixed array acquistions by creating common zone gathers to be used in dispersion analysis.

Basic first break picking done with your mouse

Plot your data however you desire to aid in identifying and picking the first arriving energy

Draw the expected airwave arrival as well as any user defined velocity line to help aid in accurate identification of the refracted/direct first arrival

Add one or a few picks and hit a single key to automatically extract picks in your current view till all picks have been made, or the waveforms become decorrelated. Fine tune picks as you need and we will fine tune the autopicks for you.

Choose to refine your automatic picks using a one of a variety of attributes to improve pick locations to the initiation of motion

Add some bounds and allow for a shot based automatic picker

Zoom in on a single trace and scale it indpendently to aid in identifying and/or refining first break picks

Use wave-path (Fresnel zone) based inversion approach as opposed to more limited ray-path based approaches

The velocity model resolution and subsequent model updates are determined by a robust wavelength dependent smoothing approach. This is in contrast to setting arbitrary square or rectangular smoothers that are not based on the physics of wave propagation, often leading to user bias.

Regularization is needed for inversion formulation and stability in most all geophysical inversions (usually an underdetermined system). In practice though, regularization has also become one of the main instruments to final model resolution and artifact suppression. We have formulated our inversion to ensure that regularization is used primarily for inversion stability, which dramatically simplifies our entire inversion system for the end user.

Use an already completed 2D surface wave analysis profile from the same line as the initial model in the refraction inversion. Helps constrain features that refraction approaches are less sensitive, for instance a velocity inversion (high velocity overlying velocity).

View all of the iterations in your inversion, to evaluate how each update changed the modeled travel-times, velocity model, and wave-path coverage. Also get updates while the inversion is running.

Can run on many CPU cores to allow for rapid solution calculations

Our computational engine is written in the current cutting edge HPC parallel implementations, allowing us to scale our algorithms to greater computational capacities in the future.

Support for shear wave refraction surveys, including all additional data QC support for simple stacking of two oppositely polarized SH sources.
