State of the Art in Information Sharing
Algan, Ugur1, R.V.L Sridhar2 (1)
Since the early nineties, the upstream industry has tried various technical approaches to the problem of sharing and re-using information in different contexts and in support of various E&P workflows. In this paper, we analyse the information sharing requirements in various workflow context scenarios in order to gain insight into what possible future approaches can be adopted to solving the information sharing problems. We then provide some ideas on how the solutions to this problem domain will evolve over the next few years, particularly as the information sharing requirements become more challenging when new technologies such as real time field operations (smart fields) enjoy wider adoption. The key scenarios are:
1) Third party applications linking to industry standard application data stores 2) Offline data conversion from one data store to another 3) Selective access to individual items in multiple data stores in order to collect and harmonize the data required for comparison purposes, or to run an application 4) Applications that use third party business objects to manage access to industry data stores 5) Data access and aggregation portals 6) Standard published views (web services) for industry standard data stores 7) Use of generic enterprise integration middleware platforms (already in use in other industries) 8) Collection, reporting, summarising, and distribution of “real-time” field information
The main issues in dealing with any of the problem classes listed above are a clear definition of the workflow context, the data requirements for the specific workflows, and steps taken to minimize data losses related to inadequate semantic correspondence of real life objects (example, one company came up with 27 different definitions of a fault!).
We also discuss how the workflow definition standardisation may have a positive impact on the manner in which our industry approaches the information sharing problems.
