Oil & Gas

ENERXICO aims to have an impact on the exploration, production, transport and refining areas of the oil and gas industry. 

ENERXICO enables the development and application of state-of-the-art computational and experimental tools for efficient industrial-scale hydrocarbon exploitation. HPC seismic modeling and inversion codes, highly consistent with real wave physics, are enhanced and evaluated within the project. Their main application is to assist on field assessment and imaging of complex Earth models, as demanded by modern oil and gas (O&G) exploration. Multiphase flows are precisely modeled during hydrocarbon production in naturally fractured reservoirs and during pipeline transportation, by means of novel and massively parallel fluid simulators with high physical fidelity. This project also aims at suitably exploiting in-silico models of new catalysts for crude oil refinement in order to reduce the dependence on traditional time-consuming laboratory experiments. Four industrial and academic partners in Europe (REPSOL, BSC, TUM, UGA) and seven similar institutions in Mexico (PEMEX, ININ, UAM-A, UNAM-FC, UNAM-IINGEN , CINVESTAV, IMP, IPN-ESIA) are jointly working in ENERXICO to improve the O&G efficiency cycle by providing and tuning these sophisticated exploitation tools.

Mitigation of uncertainties in reservoir simulation by improving the multi-physics modules of large-scale massively parallel multiphase modeling codes, to automatically combine the effects of interrelated physical and chemical phenomena. These improvements would enable accurate simulations of the in-situ recovery processes, accounting for data provided by the industrial partners. 

ENERXICO´s objectives in O&G energies:

  • Explore data processing of fine meshes to capture geological features.
  • Forecast hydrocarbon production at reservoir scale.
  • Simulate experiments that can substitute expensive real laboratory exploration for new catalysts.

Exascale outlook

Exascale target (capability/capacity)

Exploiting exascale computing for seismic wave modeling in 3D real-scale complex geologies in the presence of hydrocarbon bodies, as those found in Mexican oil and gas prospects

Main benefits expected from large increase in compute resources
  • Computationally achievable numerical modeling, being more consistent to wave physics in coupled fluid-solid, anisotropic and poro elastic materials
  • Processing and inversion of large seismic datasets as those acquired by industrial-scale marine surveys

Main challenges in harnessing large compute resources
Portability of our physically general and CPU-based codes may be challenging to small- or moderate-sized HPC systems
Specific actions towards exascale at present time Optimization of the core propagator for accelerated architectures such as GPUs and FPGAs is an ongoing work
