For StandardRESQML v2.0.1

The usage of properties has continued to evolve from their implementation in RESQML v1.1. The most important change is that properties are now independent data objects—not contained within other data objects. In addition, array data must now be stored in HDF5 (see HDF5 Files and EPC External Part Reference ).

Properties may be continuous, discrete, categorical, comments, or points. Property lookup tables are now supported so that tables of production data or relative permeability tables or any other tabulated information may now be transferred.

As in v1, properties may be grouped, for example, to simplify the transfer of reservoir simulation data, which may involve grouping multiple properties at a single time or a single property across multiple times. The grouping mechanism has been extended to support multiple realizations and more complex time relations. For example, time relations now allow field surveillance data to be grouped with “near-by” times from a simulation model for comparison.

Property types, units of measure, and their management are not specific to RESQML. As Energistics develops its common technical architecture—a foundation to be share across Energistics standards—many elements initially developed by RESQML are being moved into the shared architecture. One significant generalization for RESQML is that while v1 mandated the use of SI units, a richer set of units of measure are now supported.
