EPIM Reports User Forum - Drilling

Collaborating to create Standards for Drilling Data on the Norwegian Continental Shelf (NCS)

The EPIM Reports User Forum (RUF) is the responsible body for maintaining and enabling enhancements to the common reports to authorities and licence partners on the Norwegian Continental Shelf. The standard XML schemas and corresponding reference data resulting from collaborative projects are under continuous development by the stakeholders in the Oil & Gas industry.

The open standards' approach invites all stakeholders to propose improvements by submitting a ticket. You can follow the development of the production standard in the: Collaboration Room. Here you can find all version of the XML schemas and the proposed changes.

For more information see EPIM's website.

History and Background

The XML schema and corresponding reference data (semantics) were first developed in 2005 - 2007 with financing from OLF and the IIP project. The initial objective was to make the daily drilling reporting more efficient and consistent. This was done by developing a standard XML schema for the exchange of daily drilling reports. Elements in the XML schema are linked to concepts in the POSC Caesar Reference Data Library (RDL). The information scope of the first version covers the requirements from the authorities Petroleum Safety Authorities and Norwegian Petroleum Directorate

The first project is documented in a project report. The report can be downloaded from OLF.
