The Pipesim 2024.3 steady-state multiphase flow simulator is SLB's flagship well and network modeling software for steady-state multiphase flow simulation. Together with the Olga* dynamic multiphase flow simulator, SLB provides a complete software solution for design and optimization of production systems.

Pipesim 2024 Features

Dual-string tubing configuration

In Pipesim 2024.1, the advanced well functionality is extended to support wells with a dual string configuration, in which a pair of two parallel tubing strings are installed in the same wellbore, to enable production from or injecting to isolated zones that cannot flow simultaneously into a single tubing string.

Upgrade of the Olga S flow model to the version from Olga 2023.1

The list of available flow correlations in the Pipesim simulator is updated to include the version of the Olga S flow model from Olga 2023.1, with support for the high-definition (HD) model. The HD model represents a step-change in the fidelity of multiphase flow modeling and is a result of over 15 years of industry-sponsored research.

Gas lift design report

In Pipesim 2024.1, you have an option to generate a PDF report with all gas lift design input parameters and output results, including the comprehensive gas lift design plot. The report header includes user-defined data such as company, field, well, etc.

Upgrade of the simulation results' file format

To reduce the size of simulation result files that are stored in the pipr folder, Pipesim 2024.1 uses a new file format. This means that if you open a previously saved model using 2024.1, you will notice that the results in the new version are not displayed by default. A quick re-run is needed to visualize the results again

Enhancements in Pipesim 2024.3

• New tubing configuration for the advanced well type: Concentric tubing

• Gas lift improvement

• Python Toolkit enhancements

• Elevation data sources deprecation

New tubing configuration for the advanced well type: Concentric tubing

The advanced well type was introduced in version 2023.1 to support complex well configurations. In 2024.1, the dual string configuration was introduced to support two parallel and independent tubing strings in the same wellbore. In this release, the advanced well functionality supports concentric tubing configuration, -in-pipe" setup is installed in the wellbore to enable various scenarios, such as:

• Coiled tubing lifting, in which lift fluid is injected through the inner tubing and collected back, along with the produced completion fluid though the outer (main) tubing string.

• Gas lift systems with velocity string, in which the inner tubing is plugged, and the gas lift gas is injected through the annulus.

• Two separate fluid injections through the inner and outer tubing strings.

• Different fluid circulation scenarios for SAGD operations.

• Flow control valve on the long tubing (can be inner or outer tubing), which is used to support certain scenarios for SAGD operations.

Gas lift improvement

A new tuning factor is available for advanced well scenarios and has been added to each valve under the gas lift injection valve system. The multiplier is applied to the calculated gas flowrate through the valve. This factor may be used to match individual valve performance.

Python Toolkit enhancements

The following enhancements are available in the Python Toolkit:

• The Conda environment is upgraded to Python 3.12.3.

• To align with other IPR parameters, the new IPRFetkovitch class is available.
