Oil and Gas Ontology

PCA has, through ISO TC 184/SC4, developed a methodology for data integration across disciplines and phases and this work has been documented in ISO 15926 “Integration of lifecycle data for process plants including oil and gas production facilities”. The methodology is really a language consisting of a syntax part (ISO 15926 Part 2) and a semantic part. The syntax (or grammar) part together with domain terminology is used to develop ontologies for the different functional domains. These ontologies constitute the bases for consistent data integration within and across domains.The methodology of ISO 15926 has been used in several research projects funded by Norwegian Research Council (PETROMAKS) and important stakeholders in the Norwegian offshore industry for developing an Oil & Gas Ontology. The Integrated Information Platform (IIP) and Intelligent Data Sets (IDS) projects - both managed by DNV - has made significant contributions to this ontology in drilling, development, production and operation. However, this ontology has to be maintained, enhanced and extended to cover all the domains in the E&P value chain. In addition, Web services (domain specific software) have been developed based on this ontology.

The Oil & Gas Ontology might be express in several technologies like EXPRESS (ISO), SQL, XML, RDF and OWL. This makes it readily available for to days and future IT solutions.

Why an Oil & Gas Ontology?

The offshore industry has huge economic investments in data acquisitions, analysis, visualization, documentation and archiving. Some of the data are in use for decades and for most businesses it is the one of the main assets. Organizational units and IT systems last rarely more than few years. The most stable element in this environment is the terminologies used in the business domains along the value chain.

  • Using the methodology of ISO 15926 it is possible to create ontologies from the terminologies in use in the offshore industry to:
  • Do data integration within and across business domains
  • Create an architecture for web services
  • Include reasoning as a part of the ontology for creation of autonomous solutions
  • Include uncertainty as a part of the ontology to cope with risks
  • Be able to store data over time
  • To use the ontology as a reference ontology (meta data set) to be used in-house and between companies
  • To use the ontology in engineering
