Olga 2022.1 uses the latest version of KBC Multiflash® and provides options for use with the Symmetry process software platform fluid engine for tables. Improvements like these further expand the Olga simulator’s capabilities for carbon capture and storage (CCS) projects.

Olga 2022.1 now lets you set your composition locally for each boundary keyword. Setting standard volumetric flow rates from a mass source is another new feature that provides flexibility when running compositional cases.

The Olga 2022.1 profile generator better integrates with FieldTwin™ from FutureON. You can import U-value and steel wall thickness, populate HEATTRANSFER keywords, and create simple walls using a defined steel wall thickness, single insulation layer, and U-value from the built-in library.

Olga 2021.2 lets you use the Symmetry process software platform fluid engine in addition to KBC Multiflash® to create PVT tables with more flexibility and choice, based on field cases, while also integrating the Olga simulator with the Symmetry platform in cases where modeling common fluids between the process and the pipeline can be beneficial.:

A new HEATFLUX key has been introduced to Olga 2021.2 within the TUNING keyword. This allows tuning of the overall heat flux through the pipe wall, expanding the modeling capabilities when a deeper understanding of this phenomenon is required.

Nine new controllers have been added to Olga 2021.2 including MAX, MIN, and AVG, among others. We have also introduced several time, sample, and vector-based controllers as part of the suite. For example, you can apply the sample aggregate controller to a measured variable or signal over a given time period.

Olga now includes the updates from the NORSOK M-506 standard, incorporating organic (acetic) acids in the computation of pH. With this, Olga can now accurately simulate the effects of this on the corrosion rate

This functionality allows users to utilize equation-of-state selections for pressure/enthalpy calculations for single component systems

Olga now includes a Python API wrapper for the Olga messaging SDK. This extends the scripting capabilities in addition allowing users to take advantage of this powerful tool

FieldTwin™ design from FutureOn enables users to build and visualize a digital copy of their physical assets. Olga 2021.1 allows the import of profiles from FieldTwin directly to the Olga profile generator to use for further analysis and simulation.

The computational procedure for speed of sound has been improved. This ensures higher accuracy when operating around the critical point

Olga 2021.1 introduces improved flexibility and usability for users to assist in design of high-pressure protection systems and the associated modelling of the scenarios

Several improvements for existing CO2 capabilities have been implemented—including an improved table for single component CO2 option, improvements for the viscosity model, and priority fixes for tuning of mass transfer rate for a single-component model.

It is now possible to use a special low-pressure handling feature. When activated, if below a defined pressure threshold, the Olga simulator calculates the fluid properties and flashing with special consideration to avoid numerical problems.

Olga 2020.2 introduces a new key in the inflow performance relationship (IPR) keywords. The key can be used to select how to convert the volume flow rate of reservoir fluid at standard conditions to in situ injection rate and improves usability for such scenarios.

The HD flow model has been updated to improve its accuracy for gas condensate production systems. Extensive improved pressure-drop predictions at high gas rates for low liquid loading.

The momentum mixing across the oil/water interface has been reduced to increase oil-water slip and increase water accumulation for gravity dominated flow at high gas flow rates.

The slug initiation model is extended to include initiation of slug bubbles in bubbly flow improving prediction of slug dynamics in liquid dominated systems.

Improved pig model capabilities to simulate complex pigging scenarios involving long traveling distances, complicated pipeline geometry as well as multiple pig trains with large pressure and/or liquid discontinuities across the pigs.

The CSMA High Accuracy (HA) model for aqueous phase properties is used in Olga Compositional Tracking improving accuracy when modelling aqueous component mixtures.

The integration between Olga and Symmetry enables integration between upstream and process operations. High performance communication yields efficient data transfer and rapid insight.
