🔍 Energy: Seismic Data Searches

Petrel Workflow Searches

Find Petrel Project folders

• The Petrel application uses a main project file with extension .pet

• These project files load all additional data into the application.

• This search query will find primary project files that have been accessed within the last two years.

Petrel Projects > 2 years

Petrel Projects Modified in the last 30 days:

Archive Projects > 2 years

Find Derivative ZGY (Seismic Datasets) in Project Directories

• Petrel will use a project directory that should contain all common data such as original sgy datasets

• The extension zgy is a derivitive and should not be stored in the main .ptd directory

• The results of this search will demonstrate which users are duplicating sgy in the wrong folder

Simulation Searches

Find Error and Log data from Eclipse

• Eclipse is a reservoir simulation software

• If the application encounters an error, it will create large err files, we assume to protect the simulation data or application state at the point of issue

• These files can reach hundreds of GB in size, per error

Insight Earth Simulation Data

• Insight Earth is a niche software tool for 3D visualization, interpretation, and modeling

• It uses an extension called .insightearth

Insight Earth Extension

InsightEarth Projects

Hampson-Russell Projects

• A suite of reservoir characterization tools used in analysis

• Integrates well logs, seismic data and geophysical processes

Seismic Datasets

Find SEGY Seismic Data

• SEGY (or SGY) is a standard format for seismic data storage, widely used in subsurface imaging. Contains amplitude data for seismic traces, supporting both 2D and 3D exploration.

• This is the raw data that Petrel and other seismic interpretation tools will use

• Often candidates for Archive

Find Derivitive Seismic Data

• In Petrel workflows, files with the ZGY extension represent derivative seismic data—duplicates of the original SGY data.

• These derivative files can be recreated from the SGY files, they are often flagged as candidates for cleanup.

Find Transient Seismic Data

• VOL files represent 3D seismic volumes, used in subsurface structural mapping and reservoir characterization

• HRZ files contain interpreted horizons, aiding in geological layer analysis and stratigraphic mapping

• GRDECL files store geological grid definitions with reservoir properties,

• ZGY files are compressed seismic grids optimized for fast access.

• These are derived from SEGY or SGY data so can be recreated

Find corrupt data

• Often data pipelines will put corrupt data into folders with corrupt in the name

• This could be done manually or part of an automated process

Find user created “self-archive” folders

• Users may move data outside of automated or application pipelines but this ends up unmanaged on the filesystem

• We look for folders containing "archive" or "temp" or “old" and modified within the last 10 years but older than 3 months.
