PRODML v2.0

PRODML is an upstream oil and gas industry data-transfer standard for production management data. This domain covers the flow of fluids from the point where they enter the wellbore to the point of custody transfer, together with the results of field services and engineering analyses required in production operation workflows.

PRODML v2.0 uses these components of the Energistics Common Technical Architecture:

common v2.1
Unit of Measure (UOM) standard:
- Energistics Unit of Measure Usage Guide.pdf
- Energistics Unit Symbol Grammar.pdf
Energy Industry Profile (EIP) of ISO 19115-1:2014 v1.1.pdf
Energistics Identifier Specification

The following PRODML file resources are included in the PRODML download and are also now available from Energistics Online:

Amendment History
Std Version	Doc Version	Date	Summary of Changes
2.0	1.1	04/16/2018	Documentation update for version 2.0 of DAS content. For Energistics Online, we added the animated gif directly here (instead of referencing it). Deleted the static image and edited text accordingly. (18.1.2.1 Example: Intensity-Based, Single-Pulse DAS system) For Energistics Online, we added the animated gif directly here (instead of referencing it). Deleted the static image and edited text accordingly. (18.1.3 Measurements: Pulse Rate and Sample Locations) Improved documentation about EPC files and their role in DAS. (19.1.1.4 EPC) Clarifications to text and updated figure and caption to point out how multiple frequency bands share the same FbeDataTime array. (19.5.1 High-Level Conceptual Model) Clarified use of HDF5 and text describing examples. Updated figure. (19.5.2 Overview of the HDF5 File) Clarified use of HDF5 and text describing examples and updated the figures to include different file configuration scenarios. (19.5.3 HDF5 File Array Configuration Options) Improved language to better explain HDF5 structure and naming conventions required for DAS. Table update: changed Group to Group Path and added column for Multiplicity. Added instructions for reading/writing HDF5 groups and datasets. (19.5.4 HDF5 Structure and Naming Conventions (Required for DAS)) Changed title to current and updated content (adding more details and new info). (19.5.5 Attributes in HDF5) Updated the first UML diagram (changed cardinality on Calibration class from 0..1 to 0..*). Moved the second figure, UML diagram of HDF5 DAS arrays, to this topic. (19.6 Overview of the DAS Acquisition UML Model ) Added the new paragraph about DAS Acquisition object being derived from AbstractObject. (19.7 DAS Acquisition Object Details) Added reference to the Energistics Identifier Specification. (19.7.1 DAS Instrument Box) Added reference to the Energistics Identifier Specification. (19.7.2 Fiber Optic Path) Added a reference to HDF5 naming conventions. (19.7.4 DAS Raw) Added clarification that optional DasCustom should not be required for reading and interpreting data arrays. (19.7.5 DAS Custom) Change "should" to "must" about naming of groups in the HDF5 file. Added reference to the figure. (19.7.6 DAS Processed) Moved the figure to the topic "Overview of the DAS Acquisition UML Model" (and simply reference it in this topic). Miscellaneous text cleanup and clarified first bullet under Times arrays section. (19.8 DAS Array) Clarified details and text about timestamps and start and end times. (19.8.4 DAS Time Array) Clarified points about using DasExternalDatasetPart. (19.8.5 DAS External Dataset Part) Corrected PathInExternalFile in example data and corrected the formatting to show proper organization/hierarchy of the example data file. Added the EndTime for Part 2.h5, RawDataTime (though optional). (19.8.5.1 Example) The first version of this topic referenced DTS only. Added a local image and more information about DAS requirements. (20.3 Optical Path) Clarifications to text. Updated all figures. Changed the caption on the last figure. Moved this topic to the end of the DAS Worked Example section. (20.5 Relationships Between XML Metadata and Arrays) Updated figure. (20.6.1 DAS Acquisition) Removed time zone (which is not part of this schema). (20.6.1.1 Acquisition Timing) The example was updated, data in the table changed to reflect the update, additional text added to explain some concepts (e.g., tap test and last locus to end of fiber) and the image of the example optical path is repeated here for easy reference. (20.6.2 DAS Calibration) Incorporated the topic "DAS Raw Times" at the end of this topic. Updated both figures. Changed the name "RawTracesTimes" array to "RawDataTime" array. (20.6.3 DAS Raw data) Changed FbeData [1] to [0]. Updated both images. (20.6.4 DAS FBE data) Changed FbeTracesTime to FbeDataTime. Updated second figure. (20.6.4.1 DAS FBE ‘trace’ Times) Updated figures and corrected text to describe. Changed Spectra [1] to [0]. (20.6.5 DAS Spectra data) Updated figure and changed "SpectraTimes" array to "SpectraDataTime" array. (20.6.5.1 DAS Spectra ‘trace’ times) Added description of Use Case 6. (21 Code Examples: Use Cases) Updated definition of "gauge length" to be consistent with other parts of the documentation. (22.1 DAS Terminology)
