- Reservoir Performance workflow: this release includes new left hand navigation and asset selection at the top of the page. In addition to the navigation changes there are reservoir engineer focused metrics to which compare wells on a card (or multi-wells on a single plot) basis. Parameters utilized in WPA:
- PI
- BHP
- Average Reservoir Pressure
- DDV
- IRR
- Daily Production
- Time is normalized (1 month, 3 month, 1 year, 5 years) and the dynamic average of the wells is calculated and displayed for context on each of the cards. The sorting is worst to best. This can be resorted on-demand, and the cards can be dragged and dropped to support flexible analysis. The normalized time changed to regular datetime (for example if a certain date is known with issues in the field this can be linked to anomalies seen in the normalized time domain).
- Well Performance workflow: this release includes a high level dashboard for production tracking.
- Current artificial lift setpoints are displayed along with primary production fluid deviations from PI based forecasting day-over-day.
- A target sparkline shows how production trends for the last month vs target and the expected target for the future month.
- Upon clicking a well a production ribbon expands allowing the production engineer to assess their daily production along with calculated bottomhole pressures over time. Expansion of the opportunities ribbon will show the rod lift anomaly for sucker rod pumps and the calculated pressure traverses for wells. At the time of this release opportunities are limited to sucker rod pumps but will be expanded to other lift types in the near future.
- The Issues tab expands calculated anomalies over time to give the production engineer an assessment of the well over time. This is limited at this time to decreases in PI/production, high water cut, and high gor for flowing anomalies – in the near future this will be expanded to the other artificial lift type anomalies.
- Clicking on the well or the details button allows for level 2 view on production tracking along with productivity index over time. Additionally there is a level 2 view “Bottomhom Pressure” where multiple pressure traverses can be plotted over time.
- Data Integrity: high level metrics on what wells and production data that has been loaded into the data platform can be analyzed. All of the unique identifiers and the wells that have and are missing data can be exported to rectify data quality issues in customer source systems
