Intro

We feel the need, the need for speed – 6X is the fastest simulator on the market with an efficient robust solver.

One price gives access to all your simulation needs, delivering speed, accuracy, and flexibility for modern reservoir engineering.

Black Oil or Compositional or Hybrid Simulation

Use efficient black-oil or detailed compositional fluid models, including mid-simulation switching and hybrid workflows when it improves speed or fidelity.

Water Flooding

Optimize pattern design, voidage replacement, and sweep for waterfloods with rates, tracers, and full-field material-balance insight.

Gas Flooding

Model immiscible and near-miscible gas injection, recycling, and voidage management to improve recovery and time gas breakthrough realistically.

WAG

Simulate water-alternating-gas cycles with slug tracking, relative permeability hysteresis, and rate schedules tuned to conformance and economics.

CO2 Injection

Forecast CO2 flood performance in conventional reservoirs, including swelling, viscosity reduction, and conformance from pilots through full-field development.

Networks

Couple the reservoir model with surface networks and facilities for integrated field and gathering-system studies.

Uncertainty Analysis

Quantify subsurface uncertainty with experimental design, Monte Carlo sampling, and parameter sensitivities for decision-ready insight.

Powerful Scripting

Automate workflows and extend physics with scripting for custom models, QC, and advanced post-processing.

Calibrate models to production history, pressure data, and well tests using assisted history matching. Generate multiple valid models, quantify uncertainty, and validate against independent data for confident forecasting.

EOR Feasibility Studies

EOR Screening

Screen EOR processes for mature fields including chemical, gas, and thermal methods. Model pilot programs, predict incremental recovery and costs, and optimize injection strategies for maximum project value.

Well Placement Optimization

Drilling Optimization

Optimize well locations and trajectories across thousands of scenarios to maximize reservoir contact. Design horizontal wells, multilaterals, and infill programs considering geology, costs, and interference effects.

Production Strategy Optimization

Operating Strategy

Optimize field-wide production and injection strategies balancing well productivity, facility constraints, and pressure maintenance. Maximize NPV through rate allocation, artificial lift design, and smart well strategies.

Economic Evaluation and Risk Assessment

Multi-Well Projects

Calculate NPV, IRR, and risk-weighted economics for development and EOR projects. Generate probabilistic forecasts incorporating technical and commercial uncertainties to support investment decisions.

Reservoir Management and Optimization

Re-Frac + EOR

Optimize ongoing field operations with regularly updated models. Monitor sweep efficiency, diagnose problems, prioritize workovers, and support operational decisions with rapid scenario analysis.

Mature Field Optimization

Mature Field Management

Extend field life and maximize remaining reserves through infill drilling, pattern optimization, and EOR screening. Re-evaluate remaining oil, optimize infrastructure use, and delay abandonment economically.

New Field Development

Greenfield Development

Design greenfield developments from appraisal through startup. Optimize appraisal programs, evaluate facility concepts, establish reserves, and create development plans supporting project sanction and FID.
