Big Data Transfers are Getting Easier Thanks to RESQML
Moving massive data sets into multiple applications has always been time consuming and difficult.  Today with the use of Energistics’ RESQML open format standard, this task is becoming easier.  Click here to view video 
This demonstration features:
  • Francis Morandini from Total
  • Alice Chanvin-Laaouissi and Laurent Deny from Paradigm
  • Jana Schey and Jay Hollingsworth from Energistics 


NOTE: v2.0.1 is the stable version of RESQML, recommended for implementation in production. 


V2.0.1 adds the new data objects and capabilities listed below to RESQML v2.0 (published in September 2014). Note, the v2.0 model is exactly as published previously; the new data objects have simply been added. As such, the new objects are contained in their own packages of the RESQML UML data model (EAP file) and documented in appendices of existing RESQML documents.


New objects include:

  • Activity Model. Its purpose is to capture:
    • Tasks or actions that occurred to create and edit a subsurface model
    • How the activities relate to the data being exchanged.
  • Property Series. Makes it possible to capture the evolution of property values through time or for multiple realizations generated during stochastic processes.
  • Streamlines. In a reservoir engineering context, streamlines are a way to visualize and represent fluid flow. They have many applications; for example, they have been used as a basis for fluid flow simulation, sweep management, well rate optimization, and infill well placement.

resqml editor/validator for v2.0.1

The RESQML Editor/Validator application was created to assist adoption of RESQML. This tool enables users to explore, edit and validate RESQML v2.0.1 data objects and EPC files (the "container" file used to gather related RESQML data objects and other files for exchange among software packages).


Also available is a Command Line Validator, which may be integrated with RESQML-enabled software, to run automatically when RESQML data is imported.


The following may be downloaded from Download Standards (link above).

  • Examples and related files (explained in User Guide)

RESQML V2.0 includes use of a standard binary file format called HDF5 for transmission of large amounts of data. This standard is developed and maintained by HDF Group.


HDF5 libraries compatible with the RESQML standard may be downloaded from HDF Group.


It is important to use version 1.8.18* or higher within the 1.8.x series. Java, .NET and Python users should check wrapper for an appropriate version. It is recommended not to migrate to the 1.10.x series at this time but if it is determined that 1.10.x is needed, please send a note to Energistics explaining the rationale for further research.


* NOTE: Security issues have been identified for versions before 1.8.18. More information from HDF Group.


Use of HDF5 for RESQML is authorized by HDF Group under their license agreement.
