Geolog™ 21 is the newest version of Emerson E&P Software’s industry-leading solution for formation evaluation and petrophysical analysis. This release has been designed with user convenience in mind – from enhanced automation and new petrophysical functionalities, to increased openness through expanded connectivity to the Open Group Open Subsurface Data Universe™ (OSDU™). Geolog 21 also includes new and enhanced functionality to technologies that support additional markets, such as carbon capture and storage (CCS), geothermal energy, radioactive waste disposal and mining.

NEW FEATURES

Automatic parameter picking

A new Automated Parameter Picking module in Determin enables Quick Look multi-well petrophysical analysis.

Parameters are automatically stored in the well for immediate use in any deterministic interpretation module. 

 

Well inventory view

A new view for rapidly analyzing, filtering and selecting well data at the project scale

Provides an overview of the well data content in a project or project subset

Each type of well data can be drilled into to enumerate these instances both through the Preview option in Well Inventory view and by displaying them in Well Catalog view

Information about timing of activity for each well is provided by detailing:

The first and last audit trail entries

The number of audit trail entries

 

New tools for Determin and Multmin

Additional neutron tools added to Multimin

3 more user-defined minerals added to Multimin

XRF data can be used as input equations in a Multimin model

Neutron porosity equations rather than chart lookup can be used to compute apparent or effective porosity computation in Determin

Determin hydrocarbon corrected porosity has the option to use either Bateman-Konen porosity or a specific neutron tool porosity equation

Shale volume exponents for the Indonesia saturation model can be user-defined

 

Processing and interpretation of LWD NMR tools

New workflows for in-house processing and interpretation of NMR data from LWD tools (added to previously available wireline NMR tool support)

The following tools are supported:

Baker Hughes MagTrak NMR

Halliburton MRIL-WD NMR

Schlumberger provision

 

Updated Rock Physics module

Rock physics modeling and elastic property management in carbonates

All log and constant names are consistent across all modules

Several modules have been updated with new methods

When applicable, individual modules have been combined into a single one

A new Xu-Payne module for modeling elastic rock properties in carbonate rocks.

The Solid Grain Mixture module allows modeling of elastic properties for all minerals available in Multimin

 

Production Logging – support for array spinner tools

Expanded Production Logging functionalities to allow processing and interpretation of array production logs.

 

Geochemistry – water analysis

Geochemistry functionalities have been expanded with the addition of a water analysis workflow. This new workflow offers a variety of modules and plots to help assess:

Type and origin of the water

Water interaction with host rock and other injected fluids

Physical, electrical and thermodynamic properties

Behavior during production (scaling, corrosion)

Suitability for human use (drinking, irrigation)

 

Display of well schematics on progress plot

Used in geothermal energy and carbon capture and storage (CCS)

 

Support for OSDU R3 read/write connectivity

Loading OSDU R3 Well Log data in a Geolog Project is available with the OSDU importer module.

New log data and associated PDF files (reports, plots) can be sent from Geolog back to the OSDU R3 instance.

Support for Petrel 2021
