Introducing RF-DAP 2024.1: Discover the improvements for Catalogue, FASE and STEPS modules

We are proud to announce the latest version of RF-DAP, a platform developed by ESSS O&G to manage rock and fluid databases. This platform predicts the phase equilibria and estimates physical, thermodynamic, and transport properties of complex hydrocarbon and aqueous mixtures.

On RF-DAP 2024.1, we’ve enhanced version 2023.12 with UX Improvements and Bug Fixes for the Catalogue, Fluid Analysis and Simulation Environment (FASE), and Simulation of Thermodynamic Electrolyte Partitioning and Speciation (STEPS) modules.

In Catalogue, we updated the design for IFT and Contact Angle Experiments, enhanced print tag and share actions, and fixed files units in attachments and uploaded documents.

In FASE, we enhanced the user experience in PVT Experiments, Phase Envelope and Flash adjusting design, warning messages, input validations, and plots.

We also updated our STEPS modules to the newest version of Reaktoro v2, improving the user experience for gas and mineral streams.
