GVERSE Petrophysics
GVERSE® Petrophysics is a 64-bit petrophysical application designed to assist geoscientists and petrophysicists in analyzing and interpreting well log data and characterization of the reservoir using simple to advanced log interpretation workflows in a large multi-well multi-user environment.
GVERSE Petrophysics supports the import of digital data from numerous sources and provides you with integrated data views and analysis. Using this application you can view, edit, and analyze well log data in three different views:
- Log View
- Crossplot View
- Report View
GVERSE Petrophysics enables you to quickly analyze well log data using industry standard petrophysical algorithms. In addition, the Petrophysics Development Kit allows you to write user-defined interpretive models in C, C++, and Visual Basic programming languages for application in GVERSE Petrophysics.
GVERSE Petrophysics works on the Windows platform and is integrated with the GeoGraphix Discovery Geology applications, and GVERSE Geophysics. In GVERSE Petrophysics, you work with the active GeoGraphix project (selected in ProjectExplorer), into which you import curve data and well files, and access well data directly from the database. You can use log templates created in GVERSE Petrophysics to display wells in GVERSE Geomodeling and XSection, create cross sections from wells displayed in GVERSE Petrophysics, view WellBase information for wells displayed in GVERSE Petrophysics, and create IsoMap layers from GVERSE Petrophysics curve data statistics. In addition to these integration features, when working with well data in GeoAtlas, GVERSE Geomodeling, or XSection, you can instantly view the selected wells in GVERSE Petrophysics.

Creating Isoline Function for Buckles
Plot Long - GVERSE Petrophysics
- Use filters to pinpoint wells with raster data in specific zones, cache results for faster execution, and share a unified filter across workflows.
- Perform one-step reservoir pay summations for common reservoir attributes such as gross, net, net/gross, porosity feet, and hydrocarbon-filled porosity with corrections for true, vertical, and stratigraphic thickness
- Generate virtually any statistic from curve-derived attributes over a zone or depth interval of interest with Curve Data Statistics
- Easily confirm results using data-distribution histograms, statistics, and cross plots
- Map directly in GeoGraphix or save results to ZoneManager attributes
- Create proposed completion stages and perforation cluster intervals, then save as proposed completion records in the WellBase Completion table. These records are available for data posting symbology on the well log templates.
Petrophysical Analysis
- Skip empty curves during reservoir/pay calculations to focus on relevant data. Optimized Res/Pay summation calculations and faster processing of petrophysical results help speed up analysis.
- Easily perform quick and interactive log calculations for standard interpretations and reconnaissance with user-defined equations
- Utilize pre-written interpretations for 3 and 4-mineral determinations and Archie, Dual-Water, Indonesian, and Modified Simandoux saturation models

- Build and save personal equations with user-defined equations comprised of over 250 pre-defined standard log analysis equations
- Calculate Poisson's Ratio and Young's Modulus using mechanical properties/UDE Group
- Utilize standard Halliburton, Schlumberger, and Baker Atlas charts for environmental corrections or digitize additional charts
Curve Data Management
- Easily manage data imports with enhanced LAS tools, adding custom suffixes to imported curves and seamlessly handling well IDs. Now display full zone names in reports for clearer context.
- Import standard LAS, LBS, ASCII, DLIS, and LIS/TIF data files
- Automatically merge and splice curves using the curve import tool or optionally merge or splice at user defined depths
- Benefit from project-based mnemonic inventory, mnemonic aliases, and unit conversions
- Manually or bulk normalize curves using the graphical curve normalization utility which includes average, single, and two-point normalization methods
- Utilize single or multi-well curve copy, renaming, deletion, rescaling, min/max clipping and filter smoothing tools
- View standard core curve analysis attributes plus 200 new user-defined core curves
- Combine multiple curve mnemonics for similar curve types in hierarchical order based on a pre-determined preference
Log Analysis and Display
- Add transparency to log template data and specify cores by number for tailored analysis. Duplicate curves across tracks for efficient template design and comprehensive visual comparison.
- Control presentation templates to display curve and depth-registered images with virtually unlimited tracks, curves, colors, and pattern fills
- Display different track types including linear, logarithmic, mineral percent, depth registered images, text, core description, lithology pattern fills, tadpoles, and descriptions
- Easily cut, copy, and paste curves between tracks using the on-screen presentation editing feature
- Automatically post DST, core, perforation, mechanicals, IP, casing, tubing, and zone information
- Interactively pick and display formation and fault markers and user-defined attribute intervals
- On-screen QC editing of curves including performing simple or complex depth shifting, adjusting SP baseline shifting, and utilizing curve patch tools
Cross Plot Analysis and Display
- Display data relationships over total well depths, user-specified depth range, or one or more zone(s)
- Create three-axis display with linear or logarithmic scale, user-controlled symbols, size and color, Z-axis color spectrum, and X and Y axis histograms
Multi-Well Cross Plots
- Benefit from multi-level discrimination with user-drawn polygon capabilities
- Differentiate between wells by assigning colors to individual wells for better analysis
- Fit curves using linear regression, reduced to major axis, and polynomial regression capabilities
- Interactively determine the Formation Water Resistivity (Rw), Bound Water Resistivity (Rwb) and Cementation Exponent (m) using the Pickett plot
Customizable Reports
- Create user-defined well reports such as net pay, average porosity, water saturation, total porosity feet, or hydrocarbon-filled porosity
- Define curve choices, sample rates, depth interval, or zone selection using the provided tabular list
- Export to tab or comma delimited text files, or copy results to the Microsoft® Windows® clipboard
GVERSE Petrophysics uses a simple and intuitive scripting language. With little effort, users create sophisticated petrophysical models. These models can then be applied to individual wells for detailed analysis or to thousands of wells to generate reservoir-to-regional scale formation characterizations. Utilizing log template displays and petrophysical interpretations, users then multi-dimensionally view the petrophysical models from single-well log templates to multi-well cross sections to 3D fence diagrams.
Scalable Functionality
GVERSE Petrophysics includes over 250 predefined standard log analysis equations as well as several predefined water saturation, lithology, and coal bed methane (CBM) models. The equations are grouped into easy-to-understand families of calculations that can be copied and edited into a script to solve most formation-analysis problems. For the more sophisticated user, GVERSE Petrophysics can be linked to external models created in Visual Basic, C, or C++ code. External models offer unlimited analytical complexity as well as integration with presentation, attribute extraction, and mapping utilities.
Seamless Petrophysical Analysis, Attribute Extraction, and Mapping
Users can extract attributes generated in the petrophysical models within formation zones of interest and/or filtered well-sets for direct map layer creation, statistical analysis, or export. GVERSE Petrophysics easily links to ZoneManager, GeoGraphix attribute analysis application, to support well-by-well/zone-by-zone parameters for petrophysical models or read/write parameters for Pickett Plot analysis.
