DEFINITIONS

Following are brief descriptions of these specifications.

Data schema: XML schemas for production-oriented data objects.

  • The productFlowModel data-object can be used to capture a directed graph of flow connections in a network.
  • The productVolume data-object can capture time-varying properties within the context of a flow network. Detailed knowledge of the network is not required.
  • The productionOperation data-object can capture the activities related to production operations for a stated period (day, month, arbitrary, …).
  • The timeSeriesData data-object can capture a historian view of how data varies with time.
  • The timeSeriesStatistic data-object can capture derived statistics about timeSeriesData within a time interval.
  • The fluidSample, fluidAnalysis and fluidAnalysisResult data-objects can capture information about a fluid sample and its related lab tests.
  • The dtsInstalledSystem and dtsMeasurement data-objects can capture information related to a distributed temperature survey (DTS) in a wellbore.
  • The wellTest data-object can capture the results of a well test.
  • The wftRun data-object can capture information from one run of a wireline formation test (WFT).

Generic Data Access (DGA) service interface: A web service interface specification for accessing a persistent data store. It supports get, put and delete.

Generic Data Processor (GDP) service interface: A web service interface specification for passing data to a server in order to apply a server-specific function to that same data. The data returned from the server will represent some variation of the data initially passed by the client to the server.

PRODML Identifier: A specification for how to create a PRODML-formatted string that incorporates a hierarchy of facility identifiers. This format is specified to be used in some of the service interfaces and data-schemas.

CHANGES FROM PREVIOUS VERSIONS

Changes in PRODML v2.1 Services

  • Added new PRODML_Business_Overview.pdf file.
  • Split previous PRODML API document into individual documents for each service interface/WSDL.
    • PRODML_GDA_Service_Specification_V2.1.pdf
      § DeleteData operation added. § Replaced pseudo-code descriptions with UML diagrams. § Revamped error handling to specify the use of SOAP faults instead of return codes. § Enhanced descriptions of parameters.
    • PRODML_GDP_Service_Specification_V2.1.pdf
      § Replaced pseudo-code descriptions with UML diagrams.
      § Revamped error handling to specify the use of SOAP faults instead of return codes.
      § Enhanced descriptions of parameters.
      § Enhanced capabilities object.

    • PRODML_Identifiers_V2.1.pdf § Centralized the documentation of PRODML IDs for use in GDA, GDP, SAM and productVolume data-schema. § Clarified the format. § Changed the format to allow the type to be specified without an ID (e.g., well known points such as bottomhole do not need an ID). § Added support for a Relative PRODML ID.
    • The SAM specification was also split out but is not included in this release.

Changes in PRODML v1.2.1 data-schemas (all backward compatible).

  • Added wftRun data-schema for “Wireline Formation Tests”.
  • Added elements for “Productivity Index”.
  • Added support for internal facility parameters using a “Relative PRODML Identifier”.
