Sensor Reservoir Simulator Industry Benchmarks

Industry Benchmarks

Spe1 through spe10 are problems from the SPE Comparative Solution Projects^37-43*. The formulation options shown are those found to run best in Sensor.

Machine 1 is a 2004 vintage Dell Precision 470 workstation with 2.8 GHz Intel Xeon processors (Nocona, 1MB L2, 800 MHz FSB) running Sensor Free (32-bit) and Windows XP Professional with 2 GB RAM.

Machine 2 is a late model (mid 2007) Dell Precision 690 workstation with 3.0 GHz Intel Xeon processors (Woodcrest 5160, 4 MB L2, 1333 MHz FSB) running Sensor64 and Windows XP Professional x64 with 16 GB RAM.

The Sensor data and (Machine 1) output files are available in Downloads. Our Sensor6k evaluation version will run all these cases to completion. All CPU times are in seconds.

The following case is from Reference 1 of our Miscible page:
spe79692x3	Impes, nc=7, CFL	1000	4.06	989	984	1.9	13.8	5.3

CFL - Impes stable step logic used. NF - Nested Factorization solver option (default is RBILU(0)). D4 - Direct solver option.

Sensor's performance advantage of course varies by problem, but is not in general a function of problem size or reservoir complexity. Also compare using your cases or their examples. Run time comparisons of different models should be made on the same machine.
