The well performance dashboard is used by production engineers and field operators to look at all of the wells at scale to rapidly identify issues that are impacting production and gives recommendations to reach production targets.
The workflow allows for quick filtering of wells to groups of interest to production and field engineers to identify wells that are below their production potential.
The default ordering on the dashboard is by production below PI-based forecasting target for the wells, with the wells the most below target at the top of the page. To the right of the Prod delta target is a sparkline to indicate if the deviation from production target has been consistently trending one way or another over the past month. The slope of the dashed lines shows the next months production forecast slope to give an indication on the transient nature of the wells.
To the left of the prod delta column is the latest allocated setpoint on the well. For naturally flowing wells it will show choke position, for gas lift the injection rate, for rod lift the SPM, and for ESP the Hz of the pump. To the right of the sparkline is the high level issues summary of the wells, this allows production engineers to know if the deviation from target is caused by downtime or other issues on the well or if the production is just generally trending below target without any downtime associated to it.
The opportunity tab will show the latest date production traverse and the performance curve for the artificial lift type, below is an example of a gas lift well:
An example for an ESP well is as follows:
For Rod Lift anomalies the only current diagnostic is for flow load with the ambition for subsurface dynacards later:
The issues tab shows multiple issues currently grouped into categories for high, medium, and low:
Low issues are high water cut and gor, uncontrolled.
Medium issues are anything related to artificial lift.
High issues are downtime and critical issues that would bring the well down. The goal of this chart is to show number of issues on the well decreasing over time as more eyes are on the controllable issues associated with the well.
The time selection for the charts can be selected on the upper right hand side of the charts, as in the figure below.
For a deeper dive into the well, the user can select the view details button for level 2 pages.
The production drop down currently shows current production and PI/drawdown. Upon next release the artificial lift setpoints and smoothing of trends will be enabled to give a look at trends without noisy allocated volumes.
The Bottomhole pressure dropdown allows the users to select the pressure traverses. Later releases will include all of the calculated traverses including temperature, flow regimes, viscosity, critical rates, etc.
There are five types of anomalies flagged in the dashboard today:
- Downtime - Any well with more than 1 hour of downtime is flagged.
- High Water Cut - Increasing watercut that goes above a 80% threshold over a 7 day window.
- High GOR - Increasing GOR that goes above a 25% threshold over a 7 day window.
- Productivity Index Decline - Utilizing a 14 day average smoothed fit on the Productivity Index (outliers removed due to allocation fluctuations), if the Productivity Index declines more than 10% it will flag PI decline.
- Rod Lift Fluid Load Anomaly - Moving window of Fluid Load and SPM over a week, if the strokes per minute are constant and the fluid load increases or decreases over three consecutive days it is a flagged as a fluid load anomaly
