The Rock Physics license has received signification functionality and workflow improvements in RokDoc 2025.2. This software release focuses on making it easier to share and reproduce critical cross-plotting, log prediction, and seismic interpretation workflows that help the geoscientist deliver instant value to their teams.
We continue to makes sure that the time spent in the software is informative and that users discover and share a deeper understanding of geoscience data.
In RokDoc 2025.2, our Rock Physics toolset sees powerful upgrades to wavelet estimation and modeling workflows, providing geoscientists with enhanced capabilities for data analysis and interpretation.
Wedge Modeling with Interbeds for Seismic Net-to-Gross Modeling:
The wedge modeling tool now includes the ability to simulate interbedding effects, allowing for detailed seismic net-to-gross modeling. Users can specify the lithology, number of cycles, and net-to-gross ratio for interbedding layers, providing insights into reservoir quality and seismic attribute feasibility. This feature is invaluable for geoscientists looking to understand the impact of thin interbeds on seismic responses and improve reservoir predictions.
Multi-Well Wavelet Estimation (MWWE) Enhancements:
Previously, wavelet statistics sometimes mismatched between the QC table and well viewer. We’ve reconciled those computations and refined our sampling to handle null values more reliably. Now, you can also toggle “Use Average Wavelet” to unify the wavelet signature across multiple wells, saving time while stabilizing your final wavelet. Enjoy more comprehensive tie metrics—like cross-correlation and phase error—directly in the “Inputs” tab to keep track of each well’s time-depth adjustment and alignment. These enhancements ensure that your wavelet estimation is both accurate and efficient, allowing for more reliable seismic interpretation.
Extended Patchy Cement Model:
We’ve introduced a new “Patchy Cement (Extended)” RPM that gives new options to model connected or disconnected cement patches and additionally integrates Ikon’s Constant Cement approach to cement placement. This advanced scenario modeler helps you accurately recreate partial cementation across your rock matrix, providing a more realistic representation of subsurface conditions.
Saturation Modelling Workflow Additions:
Two anisotropic Gassmann procedures for unconventional reservoirs, Mavko Anisotropic and Brown & Korringa, are now included in the multi-well, saturation modeling workflow. These methods are perfect for exploring fluid-substitution effects in shales, tight sands, or other anisotropic environments. By incorporating these advanced techniques, users can better predict how changes in fluid content affect seismic response in multiple wells, enhancing the accuracy and efficiency of reservoir characterization work.
RPML Improvements:
A host of improvements on useability and functionality have been made in the RPML workflow. To more easily document progress and share rock physics knowledge across teams, we've improved metadata across RPML by including parameterization summaries, session description fields, and additional session indicators to help users keep track of critical information.
Parameter summary table makes the full parameterization repeatable and shareable:
In addition, subtle useability improvements have also been made. Adding new models now leaves zone prior proportions unchanged, as the new model comes in with no zones checked on. This means that when you want to test a new scenario in zone 3 of 6, there's no need to review the prior proportions in the other zones.
A “lock-down” indicator when a posterior parameter is committed now helps the user verify that the selected parameter has been saved. Finally, the Xu-Payne models now allow optimization of the T-correction factor. These improvements, along with a new regional template, are further pushing rock physics workflows into the cross-discipline collaboration stage!
The Importance of Quality Control (QC):
Quality control is a critical component of any geoscience workflow. Consistent documentation to ensure that data and interpretations are accurate and reliable is as important as the actual prediction. The log comparison tool in RokDoc 2025.2 allows users to examine the statistics of correlation between two logs, optimize lag/alignment, and filter by different geological zones and wells. This tool is essential for validating data and ensuring that interpretations are based on sound evidence.
The user-defined crossplot feature serves as a central hub for QC and validation workflows, where users can consistently display, annotate, and save images for documentation. This capability not only enhances the transparency of the analysis process but also facilitates communication and collaboration among team members.
With this release, we've further refined the user-defined plot, adding cross-plot contours, ellipses, and probability density function (PDF) overlays. With a new option to set canvas size to custom and standard aspect ratios, even more precision is possible in project documentation!
