Data Management Strategic Review

A period of rapid growth by our client had led to an exponential increase in data volumes across a wide range of corporate databases. Venture were invited to undertake a wide-ranging strategic review of their data managements systems upon which a number of information management improvement projects were identified.

Background

Our client had grown rapidly through acquisition, leading to an exponential increase in data volumes, along with a wide range of disparate databases. As a result, a major strategic review of their data managements systems was undertaken, based on which a number of projects were identified for implementation. These included:

  • Data management framework definition (standards, procedures, analysis of data storage architecture)
  • Physical data management rationalisation, with a move to digital document management
  • Digital data clean-up and rationalisation
  • Information delivery systems review and implementation
 

Outcome

Data Management Framework

We worked with IM management and end-users to define key data standards and procedures for data receipt, loading and distribution. This framework formed the foundation for all other work (e.g. digital data rationalisation, physical data clean-up and integration). The procedures defined during this phase formed a basis for an improved data management service, delivered by Venture.

Digital Data Clean-Up

A major project was set up to rationalise the large number of disparate GeoFrame project databases and apply a level of clean-up to the data using the standards developed in the framework project. This resulted in a smaller number of documented databases, containing data of known quality and consistent coverage. The project was later extended to include the transition of GeoFrame databases to the Kingdom application. The earlier clean-up and rationalisation work facilitated this process.

A project was completed to create a detailed seismic database across our client’s core areas of operation. This database includes navigation, metadata, original digital media and supporting documentation (in digital format), linked together by the application of common standards (e.g. survey naming conventions). Further work followed to clean up and integrate other databases (e.g. Terrastation), and to create a ‘corporate’ set of high quality data, accessible to all users.

Physical Archive Index Clean up and Standardisation

Venture led a major project to consolidate and “clean” physical archive indexes for subsurface data. More than 500,000 physical archive index records were consolidated from over 50 separate indexes relating to different data types, different ownerships prior to asset acquisitions, different physical archive stores and different indexing processes.

The scope of clean up work was agreed with the client following Venture’s audit of index data and recommendations for value-adding work, a step necessary to define requirements and agree a “fit for purpose” solution.

Key attributes were standardised following an earlier phase of Venture consultancy to define a set of standards for subsurface data management. The standardisation of well names across all archive indexes to the DTI standard was the most value-adding step in this context.

The clean up and standardisation of physical archive indexes has provided a platform for migrating higher quality index data to their EDMS. The work will also allow analytical work to be undertaken in support of rationalising the physical archive – something that would be much less successful on the non-standardised data (e.g. where data for the same well might appear with multiple well names with different syntaxes).

Rationalisation of Bulk Archive Data

Rationalisation of c. 4,000 “bulk” archive boxes held in offsite storage was undertaken as a priority. A project team was set up quickly to provide the resources required to review boxed data at the store, propose retention or destruction, and ensure that all items in retained boxes were indexed to record level. This work led to the destruction of more than half of the data, and a new index of 30,000+ records that had previously not been effectively searchable at item level.

EDMS Population

Following the clean up and standardisation of physical archive indexes, Venture have led the work required to migrate and load these data to Documentum. The first phase of work was a project to “map” the archive indexes to the newly defined subsurface objects in Documentum. Further refinements to the index data were required to meet EDMS requirements, and document classes have been assigned to all records following Venture’s work to propose a document classification for subsurface data.

In the second phase, Venture resources were used to load the data to Documentum and QC results. This loading work has included populating the system with electronic content for additional data sets as well as the physical archive index data. Assistance has also been provided to support development and implementation of search and order interfaces.
