As revealed in last month’s Oil IT Journal (Vol. 10 N° 12), CDA has awarded the next tranche of its Well DataStore contract to Schlumberger Information Solutions. The new, five-year contract is valued at $9 million. In our haste to go to press last month, we got one aspect of the story wrong—the technology stack that Schlumberger is to deploy in its new solution.
Seabed
Schlumberger is to deploy a three tier, web services-based architecture for CDA. The foundation datastore is a brand new database developed from the Seabed configurable data model (Oil ITJ Vol. 9 N° 10). Seabed will offer a data catalogue, and ‘enabling capabilities with regard to entitlements.’ Data access will be via the Schlumberger Integration Engine (SIE) and the presentation layer will be a version of Decision Point customized to CDA’s workflows.
WSRP
The CDA tender required a ‘forward-looking’ web-based infrastructure and Schlumberger has responded by extending its mainstream technologies with embedded Web Services for Remote Portlets (WSRP) from the OASIS organization, a protocol for aggregating content and interactive web applications from remote sources. Schlumberger is already in the process of migrating the legacy CDA data from TIF files.
ESC
The new services will be served from Schlumberger’s European Service Center (ESC) in Aberdeen, a redundant multiclient center with ‘resilient’ data storage and high-availability. Data will be accessed across the Internet or Schlumberger’s own DexaNet. Switch-over to the new system is planned for June 2006 with a phased delivery of all components of the technology stack over the following year.
