Landmark R5000 Migration

Venture were engaged by one of the major oil companies to assist them in migrating to Landmark's new software release - R5000 and migrate their seismic interpretation software - Landmark to Paradigm's EPOS interpretation system. Landmark's R5000 OpenWorks database became our client's master database.


The project was part of a global programme to rollout R5000 and migrate to Paradigm's EPOS platform. Our clients Aberdeen site was chosen as the pilot for the global programme.

Venture's project team consisted of a technical project manager, well data manager and seismic data manager with the project lasting about a year. All R5000 project activities were undertaken by Venture staff, but additional resources were provided by the client to assist in the migration of mainly seismic data from Landmark to Paradigm.

The objectives of the R5000 phase of the project were as follows:

  • Clean the seismic and well data according to those errors identified by Landmark's pre-R5000 tools
  • Archive defunct, obsolete and non-active projects prior to the migration
  • Consolidate OpenWorks databases within asset (business unit) teams
  • Clean and verify master well data into a single OpenWorks database per asset
  • Migrate to R5000.

Extensive use was made of Venture's in-house tool kit - V-DAT, to complement Landmarks pre-R5000 tool set, to build a picture of data volumes and data quality across different data sources. This proved vital in communicating the scale of the project to the business and to define the scope and cost of improvement activities to bring data to the standard required by the business.

In addition, the tools were used during the clean-up process to identify which data failed quality and business rules. By comparing data across different sources and applying data quality rules, a "gold" master dataset was created more efficiently than using more traditional and manual methods.


The project delivered on-time and to budget with business users now using Paradigm for interpretation and with a R5000 OpenWorks database containing master well data in the background.
