The Reservoir Performance screen allows users to analyze one or more wells in a customizable. Fundamentally, the data available in Reservoir Performance includes all input daily production values along with all daily computed values and diagnostics from ProdX. This page is customizable to plot any x- or y-axis values (cross plots, absolute-time-based plots, relative time plots, etc.). Reservoir performance also supports grouping/aggregation by formation, vintage, or group2/group3 from the Well table to build type curves. Once a user builds a layout, it can be saved to a template to use in the future. Most General Navigation including well selection and charting functionality applies on Reservoir Performance.

The panels of Reservoir Performance can be adjusted based on your view preferences. The well list can be collapsed by clicking on the "Wells" icon. The chart panel and map panel can be expanded or collapsed, as needed.

Wells can be selected using the well list on the left side of the screen or by selecting wells on the map. Wells can be selected from the map by clicking on a well's marker or by using the lasso tool.

Basic charting functionality including click and drag zooming, click and drag Y-axis scaling, full screen, and export are supported - more details can be found here: General Navigation.

The X and Y Axes can be adjusted by clicking on the "arrow" icon next to the unit of measure label.

The x- and y-axes can be customized by clicking the "gear" icon next to the selection arrow. Here, users can change the color (only when "View By" above the charts is "By Well"), the series type (line or scatter), the scale (log or linear), and the min/max range. When a min or max range field is left empty, it will default to autoscaling to the available data.

To save changes, click the "checkmark" icon or click the "reverse" arrow to return settings to default.

The toolbar above the charts provides various options for saving user templates, selecting time ranges, changing view options, and grouping/aggregation.

The first time Reservoir Performance is used, the default template will be loaded. Once a user configures the chart(s) and view options, they can save a template by clicking on the "Templates" dropdown, naming it, and clicking "save".

Once your template has been saved, it will immediately become active. If you make further changes to the charts or view options, a blue circle icon will appear indicating the layout no longer matches the template. Users can re-save the changes to the same template or save as a new template by entering a new name and clicking "save".

Templates can be deleted by clicking the "delete" icon.

Users can save as many templates as they would like, and they will only be visible on your account. They will persist between sessions. If there is a template you would like to be made available to everyone in your company, please contact a Xecta Customer Success Team member to assist in adding it as a global template.

The time range dropdown allows users to select between common relative time ranges. Below the time range selection is a switch to toggle between the "first" range or "last" range. For example, if you select first 3 months, all data shown will be in the first 3 months relative to each selected well. When selecting "All" for a large well count, data may take a significant amount of time to load.

Important note: Using the "first" option is extremely useful when the x-axis is set to a relative time value (like Time On Liquid, Time On Gas), but when the x-axis is set to Date Time, using the first option can be confusing.

"View By" allows users to select how data is split on charts.

Each chart displays a single well from the user's selection. To add additional series, users can click the "+" button on any of the left or right Y-axes. In "By Well", series colors can be adjusted by clicking the gear icon beside the "X" icon on each Y-Axis label.

Each chart displays a single series. Additional series can be added by clicking the large "+ Series" button to add a new chart. In by series, colors are not adjustable, but rather automatically colored by well. The x-axis can be applied to all charts or customized chart-by-chart to create a montage view of various plots.

Each chart displays a single group, but otherwise works identically to "By Series" except that x-axis options are limited. This option is only available when "Group By" (to the right of "View By") is active. Details on "Group By" can be found below.

"Group By" enables dynamic aggregation by a grouping category to establish type curves or analyze well-level performance versus a group's aggregate performance.

Important Note: "Group By" is only available when in "By Series" mode, with a limited selection of time-based X-Axis options, and all X-Axes set to the same value. Grouping is most useful for time on fields. Available X-Axis options include:

The first step of enabling grouping is selecting a category.

One a category is selected, an aggregate must be chosen. Available aggregates are:

When grouping is active and the user is in "By Series" view, an additional option called "Filter By" appears allowing the user to show wells only, groups only, or both.

Note that when in this scenario, groups are shown in the legend with a circular "group" icon beside the name to distinguish them from wells.

In this tutorial, a worked example of building initial PI decline type curves across vintages will be be shown.

Step 1: Build base charts. In this example, PI Liquid (log scale) vs. Time On Liquid for the first year of production is configured in "By Series" view.

Step 2: Select Group By -> Vintage -> Median

Step 3: Select Filter By -> Select Group Only

At this point, users will see the first year of median PI Liquid for each vintage of well in the well selection. Users can optionally save this as a template to quickly get back to this view in the future.

Optional Step 4: If users would like to see a separate chart for each group, you can switch the "View By" to "By Group"
