Petrel Workflow Searches
Find Petrel Project folders
The Petrel application uses a main project file with extension
.petThese 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
name: *.pet AND atime:[* TO now/m-2y/d] AND type:file
Petrel Projects Modified in the last 30 days:
extension:pet AND mtime:[now/m-30d/d TO now/m] AND type:file
Archive Projects > 2 years
archive AND type:directory AND mtime:[* TO now/m-2y/d]
Find Derivative ZGY (Seismic Datasets) in Project Directories
Petrel will use a project directory that should contain all common data such as original
sgydatasetsThe extension
zgyis a derivitive and should not be stored in the main .ptd directoryThe results of this search will demonstrate which users are duplicating sgy in the wrong folder
parent_path:*.ptd* AND extension:zgy
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
errfiles, we assume to protect the simulation data or application state at the point of issueThese files can reach hundreds of GB in size, per error
extension:err AND mtime:[now-10y TO now-1y] AND type:file
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
extension:insightearth AND mtime:[now-10y TO now-1y] AND type:file
InsightEarth Projects
name:.InsightEarth
Hampson-Russell Projects
A suite of reservoir characterization tools used in analysis
Integrates well logs, seismic data and geophysical processes
name:*prj OR name:*.wdb AND (parent_path:\/Houston\-Prod\-rivafs01\/lin\/data OR parent_path:\/Houston\-Prod\-rivafs01\/lin\/data*) AND type:directory
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
type:file AND extension:(segy OR sgy)
Find Derivitive Seismic Data
In Petrel workflows, files with the
ZGYextension represent derivative seismic data—duplicates of the original SGY data.These derivative files can be recreated from the
SGYfiles, they are often flagged as candidates for cleanup.
type:file AND extension:(zgy)
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
type:file AND extension:(vol OR hrz OR grdecl OR zgy) AND mtime:[now-10y TO now-3M]
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
name.text:*corrupt* AND type:directory AND mtime:[now-10y TO now-3M]
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.
name:(*archive* OR *temp* OR *old*) AND mtime:[now-10y TO now-3M]
