System for Efficient Numerical Simulation of Oil Recovery

The Real Advantage in Simulation

  • A True Step-Change in compositional and black oil reservoir simulator performance and reliability - a synergistic result of superior method, formulation and convergence, linear solvers, and implementation

  • Common 10x speedup for compositional

  • 64-bit systems make Sensor 64 the simplest, most accurate, and most efficient reservoir simulator for cases up to 320 million cells Impes, 80 million cells Implicit (on Windows 8)

  • Obliterates parallel model run rate -  Sensor 64 and simultaneous serial computing within your forecasting, history matching and optimization workflows maximize system efficiency and output

  • Run unlimited numbers of simultaneous Sensor jobs on a single node-locked license - the only limit on the numbers of simultaneous users and runs is machine memory - Sensor is two orders of magnitude more cost-effective than any other reservoir simulator, serial or parallel

  • Sensor "senses" and informs of extreme and non-physical specifications, and detects and deals with difficult numerical situations, to avoid potentially large errors and inefficiencies

  • Unprecedented reliability and stability, far fewer tuning controls, and minimal tuning requirements allow you to spend your time studying the reservoir instead of fighting the model

  • Assisted History Matching and Predictive Optimization Solutions using Lynx (Nitec), Mepo, and Enable

    and using Pipe-it workflow integration and optimization software (Tieto):

    • SensorMatch - automated workflow for deterministic or probabilistic upscaling and history matching

    • SensorCast   - automated workflow for deterministic predictive optimization and forecasting

    • SensorPCast - automated  workflow for probabilistic predictive optimization and forecasting

    • SensorPOpt - automated  workflow for probabilistic discrete alternative optimization

    • SensorPx / Makespx / Makeoptdat / Sensor Uncertain Inputs - basic and efficient tools and features enabling the probabilistic automatic optimization solutions

  • Uniquely substantiated by reproducible Benchmarks and examples
