Why You Can Trust G2's Software Rankings:
G2's software rankings are built on verified user reviews, rigorous moderation, and a consistent research methodology maintained by a team of analysts and data experts. Each product is measured using the same transparent criteria, with no paid placement or vendor influence. While reviews reflect real user experiences, which can be subjective, they offer valuable insight into how software performs in the hands of professionals. Together, these inputs power the G2 Score, a standardized way to compare tools within every category.

The TECHBASE Oil and Gas Package plots down hole data and maps, and stores your data in a TECHBASE database. Composite and locates your data within boundaries, then you can choose between 7 modeling algorithms to interpret your surface and subsurface data
Octopus provides a practical tool that will enhance the engineering capabilities of the office based engineer involved in field development.This application is used to assist in the optimised design of multi-well field development projects.
Terastation II is designed for use by geologists, petrophysicists and other technical earth scientists for the use of stress analysis and project management.
THERMOFLEX is a modular program with a graphical interface that allows you to assemble a model from icons representing over one hundred and seventy-five different components. The program covers both design and off-design simulation, and models all types of power plants, including combined cycles, conventional steam cycles, and repowering. It can also model general thermal power systems and networks.
Time Dynamic Volumetric Balancing (TDVB) models the migration of reservoir fluids (oil, gas, and water) through time.ReservoirGrail's TDVB technology models the reservoir production using the drainage functions and the historical production data.
TomoXPro is a crosshole software package that includes crosshole survey design, model building and modeling, data pre-processing, and more with capabilities you need for performing your project.
Vecon is a 2D/3D VSP and surface seismic design and modeling system that makes completion of a variety of jobs with features to help manage efficiency.
Velosi PSRA® is a specialized Petrol Station Risk Assessment and Inspection Management Software designed to improve safety and compliance across fuel retail environments. Built in accordance with industry guidelines such as NFPA 30A and HS(G) 146, it helps organizations identify fire, explosion, and operational hazards, assess risks, and manage inspection activities. The platform ensures structured safety evaluations, documentation of findings, corrective actions tracking, and continuous risk monitoring for petrol station operations.
Virtual Oil Platform provides health, safety, environment, and training capabilities to help you gain knowledge and skills on how to deal with the challenges that can occur on a rig or platform.
VisualPVT is your indispensable aide enabling accurate modeling of reservoir fluids and operating procedures under the compositional data constrains, when use of relevant empirical dependences (correlations) is required. The software includes about 150 correlations for oil, gas and water. Each correlation is open for on-the-fly modifications via the unique embedded VBA-based editor, thus, no programming skills are required. Add new correlations and exchange them freely with other VisualPVT software users in virtue of the permissive license.
GASMOD is a fully integrated gas reservoir/multi-phase pipeline simulator, capable of modelling large and small gas properties.
Volsung offers an integrated solution to comprehensively model and simulate your geothermal process, from subsurface reservoirs to surface systems. Gain unparalleled clarity, ensure optimal system performance, and confidently make data-driven decisions. Join us in shaping the future of geothermal energy.
The Thermodynamic Model of Waxes (WAXModelR) computer program is capable of simulating the wax phase behavior of reservoir fluids. The WAXModelR can calculate the complete wax deposition envelope (WDE) of a reservoir fluid, including wax quality lines and much more.
Weatherford is a 3D visualization tool to serve as a safety tool for international oil rig personnel to help you manage your training safety material.
WellAna allows treatment of multiple zones with different stimulation properties, reservoir matrix properties and reservoir size. Crossflow between zones and wellbore storage transients are properly handled. Several different hydraulic fracture behavior models can be specified for each zone.
