RockWare PetraSim: A Technical Review for Subsurface Simulation Specialists

For Reservoir Engineers and Simulation Specialists focused on specific subsurface processes beyond conventional oil and gas recovery, selecting the appropriate simulation software is critical. RockWare PetraSim serves as a dedicated graphical user interface (GUI) for the established TOUGH2 family of numerical simulators.

This overview details its core functionalities and applications, helping professionals determine its fit for projects involving geothermal reservoirs, CO2 sequestration, and multi-phase contaminant transport. It offers a structured approach to model setup and results visualization for these complex scenarios.

Overview of RockWare PetraSim Capabilities

RockWare PetraSim provides an interactive 3D environment designed to simplify the setup and visualization of complex subsurface simulations. The software acts as a pre- and post-processor, streamlining the workflow for engineers utilizing the TOUGH2 suite of codes developed at Lawrence Berkeley National Laboratory.

Integrated TOUGH2 Family Simulators

A key feature of RockWare PetraSim is its direct integration with a range of TOUGH2 family executables. This bundling allows users to run simulations directly from the PetraSim interface, leveraging the robust calculation engines of these specialized simulators.

• TOUGH2: The foundational simulator for coupled fluid and heat flow in porous and fractured media.
• T2VOC: Extends TOUGH2 capabilities to include transport of volatile organic compounds.
• TMVOC: Designed for simulating multiphase, multicomponent flow of hydrocarbons.
• TOUGHREACT: Couples reactive transport with fluid flow and heat transport.

Beyond these bundled options, PetraSim also facilitates the creation of input files compatible with the TOUGH3 simulator and is capable of visualizing its CSV output, ensuring flexibility for evolving project needs.

Interactive 3D Model Creation and Property Assignment

The software offers tools for building detailed 3D models of subsurface environments. This includes the ability to import existing 3D layer data to define complex geological geometries. Once the geometry is established, engineers can assign material properties to each layer, which is essential for accurately representing heterogeneous reservoir characteristics within the simulation. This visual approach aims to enhance model conceptualization and reduce setup time.

Specialized Applications in Subsurface Modeling

Unlike conventional black-oil or compositional simulators primarily focused on hydrocarbon recovery, RockWare PetraSim’s design and integrated simulators are tailored for specific, challenging subsurface applications. Its core relevance lies in areas requiring detailed understanding of multi-phase flow, heat transfer, and chemical reactions.

Geothermal Reservoir Engineering

For geothermal projects, PetraSim provides the necessary framework to model heat and fluid flow within geothermal reservoirs. Its ability to handle high-temperature, high-pressure, and multi-phase conditions makes it suitable for optimizing well placement, predicting resource longevity, and assessing energy extraction strategies. Applications of the TOUGH2 family, such as those at Indonesia’s Dieng field, highlight the relevance of this tool.

CO2 Sequestration and Carbon Storage

In the context of carbon capture, utilization, and storage (CCUS), PetraSim supports the simulation of CO2 injection, migration, and long-term storage within saline aquifers or depleted reservoirs. The software’s capabilities for modeling multi-phase flow and geochemical interactions are critical for assessing storage integrity, predicting plume movement, and evaluating potential leakage risks.

Multi-Phase Contaminant Transport

Environmental engineering applications often require understanding how contaminants move through geological formations. PetraSim, particularly with simulators like T2VOC and TMVOC, enables the modeling of multi-phase contaminant transport. This is vital for site characterization, risk assessment, and designing remediation strategies for contaminated groundwater and soil, as seen in problems like Yucca Mountain groundwater flow.

RockWare PetraSim: A Differentiated Approach to Simulation

It is important for Reservoir Engineers and Simulation Specialists to recognize the distinct positioning of RockWare PetraSim within the broader simulation software landscape. PetraSim is not designed as a direct competitor to general-purpose black-oil or compositional reservoir simulators used for primary or secondary oil and gas recovery. Instead, it serves as a specialized front-end for the TOUGH2 family, whose strengths are in non-isothermal, multi-phase, multi-component flow and reactive transport problems. This focus ensures that professionals engaged in geothermal energy, CO2 storage, or complex environmental remediation have a tool specifically engineered for their unique challenges.
