Following last year’s merger, StatoilHydro has standardized on one common OpenWorks/SeisWorks (OW/SW) platform for G&G data—with Schlumberger’s Petrel used for reservoir modeling. Petrel, as essentially a ‘single user’ tool has proved difficult to integrate into corporate environments. Cathrine Gunnesdal described how StatoilHydro is ‘taking control’ of Petrel, moving it into a multi-user environment and developing a methodology for systematic Petrel project building from its OW/SW master data sets, for capturing model interpretations into a results database and back populating reference data to the corporate store.
The new workflow begins with project loading—using approved reference and horizon lists from the OW/SW database into local Petrel projects. Project building currently takes around 16 days—but this is expected to shorten with experience. Petrel projects have read write/access to a local ‘results’ database. When the modeler is through, a project data manager intervenes to quality control data prior to upload to the reference database and back populate the OW/SW store.
The workflow relies on defined roles and responsibilities—with a dialogue between end users and data managers for data snapshots at significant milestones and ‘decision gates.’ Naming conventions, Petrel file folder structures and access rights are standardized and closely controlled. All Petrel projects are globally stored using the standard disk structure. Petrel coordinate reference systems are inherited from the OW/SW via the OpenSpirit interface. Schlumberger’s ProSource with its GIS viewer is used to browse the Petrel projects on disk.
The technique was successfully piloted on StatoilHydro’s Jeanne D’Arc project—with work shared between Oslo and Calgary. Enterprise level deployment and training is now underway.

Ann-Christin Schill (StatoilHydro) introduced the new ‘E&P Information Management’ (EPIM) organization, an umbrella group tasked with taking control of three of Norway’s prior e-regulatory initiatives—LicenseWeb, AuthorityWeb and EnvironmentWeb. EPIM’s objective is to develop IT solutions that facilitate information flow between authorities and licensees involved in exploration, production and transport on the Norwegian Continental Shelf (NCS). EPIM began operation in January 2008 and has administrative support from the Norwegian OLF trade body. To date 33 operators have joined the association. E-regulation and reporting has benefited from the same Secured Oil Information Link (SOIL) network that has been the backbone of Norway’s DISKOS/Petrobank data sharing initiative for more than a decade. Although cost considerations and new technology mean that alternatives to the dedicated SOIL network are being evaluated. More from www.epim.no.
