The Next Generation Work Station Ready Well-Logs (WSR) December 2018 Karl Brand, BHP Vaibav Kumar, Infosys Vilas Torgal, Infosys Well-logs represent a critical data asset in the Petroleum Geoscience community, since they ultimately are used to define the reserve asset base. BHP has collected hundreds of thousands of digital well-logs through acquisition, contractors, vendor purchases, free downloads, and agreements with oil and gas companies in projects over the past several decades. Searching for the right data in multiple locations and then manual conversion of raw logs into Work Station Ready (WSR) data took hours to generate. BHP needed to automate the process of generating the standard WSR log-sets, and then automatically deliver the WSR log-set to the appropriate interpretation application. In order to achieve this objective, it was important to have all the well-log data in a centralized repository, define well log standards, processes, curve quality, and log classification taxonomy to ensure right curves are picked up for generating WSR log-set. BHP’s BHDM (Borehole Data Management System) solution created a corporate, single source of truth for all the well log data for the Petroleum business units. The BHDM is the definitive repository for all borehole data, which all other systems will reference. When the BHDM solution was implemented, it focused on the Shale assets. Over the course of the ensuing years, BHP rolled-out the solution to multiple petroleum assets in both Shale and Conventional. BHDM web-based service allows users to locate wells on a map with several culture/shape layers and query required data types. All BHDM wells are associated with existing well data in the Well Master Database. With all the data loaded into the centralized repository, the next step was to build the WSR process, which would create the WSR log-set, and then automatically deliver it to interpretation applications. The development of the current WSR process entailed three maturity stages: 1. Development of the Process (Generation One) 2. Implementation of Business Unit Refinements (Generation Two) 3. Improve Curve Selection Process and Improve Standards (The Next Generation) During the first half of 2018, BHP executed a project to create the Next Generation WSR to advance the automated process. The Next Generation WSR solution went live during third quarter of 2018. This sustainable process assures WSR data quality, integrity, and provides consistent and standard WSR log set to the geoscience and subsurface teams. The WSR process has reduced project cycle times, reduced well-planning risks, enhanced cross-discipline collaboration, and more informed decisions
