Olga dynamic multiphase flow simulator
The industry-standard tool for dynamic multiphase flow simulation
Overview
Over 30 years of research and development
Customer-supported innovation and research has been at the core of the Olga simulator’s development for more than 30 years. Validation of the Olga code with large-scale lab research and the largest database of actual production data from leading E&P companies are key factors in its ongoing development.
Major oil and engineering companies participate in the Olga Verification and Improvement Project (OVIP), which has collected the world’s largest database of lab and field data. This data has been used to validate and adapt the multiphase flow models. Results are continuously implemented in the Olga simulator, improving the core technology to better match the realities of operations.
Additionally, the Horizon project is cosponsored by seven major oil companies, which addresses problems related to the cost-effective development and safe operation of long-distance gas-condensate transport and long-distance transport of oil well streams.
OLGA Dynamic Multiphase Flow Simulator
Announcement
Equinor awards SLB contract for Leak Detection System for Johan Sverdrup Phase-II development
Equinor has, through a technical qualification study, selected SLB for delivering a novel Leak Detection and Virtual Flow Metering solution for the multiphase production network in Johan Sverdrup Phase II. The solution is based on the Olga Online* technology.
Olga simulator single phase
In Olga 2024.1 we are introducing first stage release of our Olga single phase solution. This will be a lighter and faster version of the Olga simulator for handling single phase only. The improved version of the Olga simulator will minimize set of calculations required for pure single-phase flow to maximize simulation speed. This way we can considerably improve efficiency and usability for the Olga simulator when applied to single phase systems such as hydrogen simulations.
Compositional tracking with Symmetry
Olga 2024.1 is released with the possibility of using the Symmetry process simulation software fluids engine as an option for compositional tracking. Symmetry software can be selected as the compositional engine under COMPOPTION in the Olga simulator. The Symmetry software fluids engine is a powerful and accurate thermodynamics engine part of the SLB software offering, bringing consistent thermodynamics from pore to product.
Network segments freeze
Olga 2024.1 is released with the possibility of freezing the transient calculations for a branch. This is done by adding “SIMULATIOINOPTIONS” for a flow path and setting the “TRANSIENT” key to “FREEZE” or “NOFLOW”. If “FREEZE” is selected no calculations are done for the flow path. If “NOFLOW” is selected only temperature calculations are conducted, where only thermal capacity of the fluid is considered.
VKH and IKH calculations
Olga 2024.1 is released with Inviscid Kelvin–Helmholtz (IKH) and Viscous Kelvin–Helmholtz (VKH) stability indicators as output. VKH instability combined with stratified flow may indicate large wave flow in the system. The user can then investigate wave formation and propagation using a fine grid dynamic Olga simulator model and the 2nd order mass equation scheme in the Olga simulator.
Multiflash 7.4
The Multiflash library has been updated from the previous release from 7.3 to 7.4. Version 7.4 has the following important updates:
• Improved accuracy for CO2 modelling.
• Improved CO2 hydrates model.
• Improved PH flash stability.
• Improved GERG-2008/EOS-CG.
• AGA-8 density support.
• Improved data regression.
• Polymers modelling and perturbed chain statistical associating fluid theory (PC-SAFT).
Windows 11 compatibility
Olga 2024.1 has been tested with Windows 11 and found compatible.
