The lack of a global, consistent and reliable system for well/wellbore identification has been a long-standing issue. Industry professionals believe the heart of the problem is the lack of consistent definitions and best practices.

A major oil company has devised a solution, based on creating unique well identifiers (UWIs), that helps establish internal consistencies and best practices across the company's operating units. The generation of UWIs leverages the company's standardized computing environment for its subsurface data, and extends the computing environment to encompass engineering workflows and, by facilitating ties to back-office systems, enables integration with business processes. The effort to define and devise a comprehensive solution was managed as an upstream business improvement initiative to address the following key issues, and as such, was widely accepted and supported within the company.

  • Business process integration

  • Revision of individual operating unit UWI practices to avoid diluting the benefits of a standardized computing environment

  • Re-evaluation of data vendors to improve inadequate well-data coverage and responsiveness.

  • Avoidance of costly and inefficient data trades by developing a better understanding of the data already owned, before purchasing new data.

This presentation will describe the resulting workflow whereby data from the well engineering database flows to the subsurface corporate well database and from there onwards to project databases once drilling begins. A workflow example explains how geoscientists can receive updates of trajectory data on-demand, thereby eliminating data re-entry and ensuring data correlation between the well engineering database and the project database.
