ECHELON's accuracy and speed play a critical role in the characterization of the Permian Basin unconventional reservoir.
ECHELON software is a massively parallel, fully-implicit, extended black-oil reservoir simulator built from the ground-up for exceptional speed. GPU hardware, modern solver algorithms and careful implementation are combined in ECHELON software to allow the simulation of hundreds to thousands of realizations of large complex models in vastly less time than legacy solutions while using fewer hardware resources.
Four realizations of the 16 million cell model were simultaneously run on a single Cray CS-Storm 2U node consisting of 8 NVIDIA Tesla K80 GPUs (Fig. 2). The run time for all 100 realizations for both the dual-porosity and dual-permeability descriptions with 20 years of production are shown below.
|Model(16M cells)||Wall time for 100 runs on 2U node with 8 Tesla K80s||Avg. time per job (in mins.)||Speed upper job over standard simulator|
|Dual Porosity||5.0 hrs.||12||28|
|Dual Permeability||5.7 hrs.||13.8||48|
