We are proud to announce the release of RF-DAP version 2025.3!
You’ll discover several enhancements, new features, and bug fixes to improve your experience.
The User Guide is now more comprehensive! Building on the existing FASE User Guide, we’ve added the Catalogue and STEPS User Guide, all accessible through the help button, marked with a question mark icon (?). This user guide provides a step-by-step manual on these modules,

We’ve added the Mercury Injection Experiment (MICP) in Catalogue. Now you can seamlessly save and share mercury injection experimental results. This enhancement gives you valuable insights into reservoir rock properties by enabling you to calculate Pore Throat Distributions, Capillary Pressure, and Permeability estimations, as illustrated in Figure 2.

We have enhanced the Permeability Experiment interface and results analysis. The results for permeability using Darcy’s Law are now shown in a plot, and you can now apply Klinkenberg and Forchheimer corrections. All for a more accurate assessment of absolute permeability by accounting for gas-slippage and inertial (non-Darcy) flow effects, respectively.
The new Centrifuge Experiment is now available in SCAS! This powerful feature allows you to simulate and optimize relative permeability and capillary pressure curves, offering deeper insights into two-phase fluid flow within your core samples, as illustrated in Figure 3.

You’ll also find new Analytical Methods to enhance your data analysis. You can now obtain relative permeability curves using the Jones & Roszelle methods in single-stage unsteady-state Coreflooding simulations. Additionally, capillary pressure can be derived from Splines-Nordtvedt, Jones, and Hassler-Brunner methods, providing a more comprehensive suite of tools for your centrifuge simulations, as shown in Figure 4.

The History Matching functionality has been improved with new options for configuring theoptimization parameters for both Corey and LET relative permeability models, giving you greater simulation control and precision.
The Carbon Capture and Storage Module has been enhanced with new equations of state (EoSs) and expanded capabilities. The Leachman Equation of State is now available for H2 modeling, as demonstrated in Figure 5, and both the GERG-2008 and EoS-CG models can now handle compositions containing water, providing greater accuracy for a wider range of fluid systems.

You can now perform the preparation of a fluid using either pH only or pH and alkalinity reconciliation. This new preparation option provides greater flexibility to match experimental or target values, as shown in Figure 6.

We’ve improved the user experience for volume unit selection. The system now displays a warning if the database is missing molar volume data for any stream species, enabling you to adjust compositions before running equilibrium calculations.
