: Pipesim 2026.1 includes Multiflash 7.6 by default, enhancing compositional fluid modeling capabilities.
The sink of the model. Pipesim simulation requires a boundary condition here, typically fixed pressure (e.g., 150 psi separator pressure).
PIPESIM 2024.1 introduced support for 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 isolated zones that cannot flow simultaneously into a single tubing string. This feature continues to be refined in 2025.1, providing more flexible well architecture modeling.
A common industry question involves the relationship between Pipesim and OLGA. These are complementary rather than competing products. Pipesim is optimized for — evaluating system behavior under stable conditions, ideal for front-end design and production optimization. OLGA specializes in dynamic simulation — analyzing transient events such as startups, shutdowns, slugging behavior, and hydrate kinetics.
Predicts heat loss along insulated buried lines. Key Features and Simulation Capabilities Multiphase Flow Engines
For subsea engineers, PIPESIM is vital for sizing pipelines. It helps calculate pressure drops across miles of seabed terrain. It ensures that the pipe diameter is large enough to handle flow without excessive friction, but not so large that the fluid velocity is too low (which causes sand settling and water accumulation).
Determining the optimal tubing size to maximize production without exceeding flow capacity.
PIPESIM's value comes from a vast library of physical models and simulation workflows built into a single, integrated platform. Its key capabilities include:
When reservoir pressure is insufficient to lift fluids to the surface, artificial lift becomes necessary. Pipesim provides comprehensive workflows for designing and selecting optimal electric submersible pumps (ESPs) or gas lift systems, with the ability to model sucker-rod pumps and progressing cavity pumps (PCPs).
Flow assurance is arguably the most critical use case for PIPESIM. As wells mature, they often produce water along with oil and gas. This mixture creates chemical and physical challenges. PIPESIM allows engineers to predict and mitigate:
: The PythonToolkit (PTK) has been upgraded with support for spot report results, user-defined metocean data, and an upgraded Python 3.13 environment, enabling powerful automation and integration workflows.
This article delves deep into the fundamentals, applications, and best practices of using Pipesim simulation, providing a roadmap for turning raw data into actionable insights.
VLP curves represent the pressure required to lift the fluid from the reservoir to the surface. The simulator includes a wide library of multiphase flow correlations (e.g., Beggs & Brill, Ansari, and OLGA) to calculate pressure drops and liquid holdup accurately.
