Core Capabilities for Reservoir Engineering Workflows

PVTsim Nova offers a suite of functionalities tailored for comprehensive fluid characterization and EoS model development, supporting complex phase equilibria relevant to various upstream and midstream challenges.

Automated EoS Model Development: “Auto EoS”

One of PVTsim Nova’s key features is its Auto EoS capability. This function automates the process of building a fluid model rapidly, often within minutes, directly from imported PVT data. It is designed to quickly generate accurate EoS models, reducing the manual effort and time typically associated with fluid characterization.

Extensive Simulator Integration

A critical aspect of PVTsim Nova is its broad compatibility. The software includes interfaces to more than 30 different reservoir, flow-assurance, and process simulators. This extensive list includes widely used platforms such as Eclipse, INTERSECT, tNavigator, IMEX, Nexus, OLGA, and LedaFlow, ensuring that developed fluid models can be seamlessly exported and utilized across various simulation environments.

Advanced Polar Models for Complex Systems

PVTsim Nova supports advanced polar models, which are crucial for accurately describing complex phase equilibria. These models are particularly relevant when dealing with systems involving water, hydrate inhibitors, and CO2, where standard EoS models may fall short. The reliability of these models is supported by validation reports, ensuring confidence in predictions for challenging fluid compositions.

Input Data Quality Control (QC)

To ensure the integrity of the EoS modeling process, PVTsim Nova incorporates a Quality-Check (QC) module. This module verifies the quality of input fluid-composition data before any EoS modeling commences. By identifying and addressing potential data issues early, the QC module helps prevent errors and ensures the robustness of the resulting fluid models.

What Sets PVTsim Nova Apart

Unlike some integrated solutions, PVTsim Nova distinguishes itself as an independent and simulator-agnostic PVT package. Its primary design philosophy is to provide robust fluid modeling capabilities that are explicitly built to export into a broad range of third-party reservoir, flow-assurance, and process simulators. This approach offers flexibility, allowing engineers to develop precise fluid models independent of a single vendor’s simulator family, contrasting with tools like Schlumberger Fluidmodeler, which is often tied to a specific simulator ecosystem.

Training and Expertise

The foundation of PVTsim Nova is built upon over 30 years of experience in PVT and phase-behavior training. This pedigree underscores a deep understanding of the underlying science and practical application required for accurate fluid characterization. Dedicated training courses on PVT and phase behavior are available, catering to various specialists including reservoir engineers, process engineers, flow-assurance/multiphase-metering engineers, and laboratory staff, reinforcing the software’s comprehensive support for users across disciplines.

Competing and Related Software in PVT and Phase Behavior
