The rise in important initiatives such as asset modelling & well integrity assessment in ADCO has clearly identified the need for effectively managing the down-hole completion data across drilling and assets. The down-hole completion data has become more strategic to ADCO. The completion schematic standards, data visualization, phase-out legacy systems for preparation of down-hole schematic, data ownership & data integration amongst other challenges which were addressed as part of this automation project.

The previous/old workflow utilizes third-party visualization software to display downhole completions equipment. However, well schematics being generated by these workflows displayed are standardized images and are not data-driven. The engineer will essentially build up the image separately and then enter the data into well-schematic as primarily text-based data entry. This leads to creation and maintenance of multiple reports, spreadsheets and other sources of data to inform the engineer as to the current status of downhole equipment in the wellbore. Well integrity assessment (such as MAASP calculations…etc) and well performance modelling (Inflow performance calculation) has clearly impacted due to unavailability of completion data at right time. The new prescribed workflow acts as a bridge between the drilling and assets. This automated workflow enhanced the data quality by using standard data entry template and visualization solution using standard completion templates (single, dual, smart completion…etc) and completion symbols which involves managing the time required from the drilling engineers, completion engineers and drilling supervisors. There are guidelines for data quality checking through the use of data validation rules and verification using visualization has been established in this automated workflow. The workflow has identified the business and data interfaces required to be considered for automation. The petroleum engineers are notified in their real time optimization solution when a new well completion has been added and whenever there is a change in existing well configuration & completion design and prompt them to create or update the well performance models. The data is also retrieved for well integrity purposes as well with notifications.

The Engineers are required to understand mechanism and workflows governing the usage of this automated workflow, so that they generate reliable and sustainable well-schematics templates in a self-sufficient process, certain tasks may be performed in advance to increase efficiency of the workflow and reduce overall time spent in data preparation and generating a complete well-schematic for the hand-over. The templates that satisfy business and technical criteria, an engineer can make huge time gains while generating well-schematics.

This workflow automation further facilitated as common access point for all required completion data with clear data ownership, governance, standard visualizations & schematics & ensures the availability of the data at the right time
