Updated October 3, 2024

Many of the decisions made by oil and gas companies rely on simulations of deposits, wells, infrastructure, and operations. Companies use oil and gas simulation and modeling software to create realistic representations of reservoirs, equipment use, and resistivity, as well as environmental effects. This type of software helps oil and gas companies predict exploration or production results, and assess risks that may impact safety and profitability.

Oil and gas simulation and modeling software uses data from systems such as [geology and seismic](https://www.g2.com/categories/geology-and-seismic), [exploration](https://www.g2.com/categories/exploration), and production in order to create accurate models and simulations.

To qualify for inclusion in the Oil and Gas Simulation and Modeling category, a product must:

- Provide customizable pre-defined models for activities like explorations and drilling
- Create and compare simulation scenarios with different parameters
- Capture and manage characteristics of hydrocarbons such as fluidity, pressure, or temperature
- Predict and evaluate risks that can impact safety or productivity
- Simulate processes based on standard procedures and best practices
- Support decision making by providing reporting and analytics on simulations
