# BestDay views
The BestDay application consists of three views where you can view and work with production performances indicators on different detail levels. When you open BestDay, you are directed to the KPI dashboard, where you'll find key performance indicators across system levels, as well as aggregated production, deferment, and deviation data. In the Well Summary view, you can search, analyze, and prioritize between wells to further explore through the Deep dive view, where you will be able to analyze the individual systems or wells more in-depth, and resolve identified production deviations.

# KPI dashboard
This view dispays cards with key performance indicators and different panels where you can investigate the details.
These are the KPI cards:
Gross production shows the production of all liquids, including water and impurities.
Hydrocarbon shows the sum of all hydrocarbon production.
Deferments show deferment volume per day.
Deviations show deviation volume per day and number of deviations. You can choose between seeing total sums or the daily averages for a set time range.
The Breakdown by product panel shows values for actual production, the BestDay capacity estimation and other capacity references, deferments, and deviations. Showing all products is the default setting, but you can select products with the checkboxes at the top of the panel.
Next is the Production bar chart, which visualizes actual production. You can compare the production capacity to the BestDay data-driven capacity and other capacity references, such as IPSC. You can also select to see the deviations between the actual and estimated production. This is illustrated with a grey shaded area on the chart. Show or hide a box with daily details with Show values on hover.
Scroll further to see the Deviations and Deferments volume lined up side by side. A gap between the two indicates a reason for investigating the optimization potential. Click Split by status count to display the amount of detected and ignored deviations and planned and unplanned deferments. Notice that both the Deviation and Deferments side panels are available on the right side of the page to give you easy access to more details, such as event distributions.
The last panel displays Production efficiency per product. The efficiency calculation is (Actual production/Capacity)x100%. By default, the BestDay data-driven capacity is used. You can change this with the dropdown list per product located at the top of the panel.
# Well summary view
Prioritize between wells on the Well summary page with an aggregated view of the entire field/branch/country, per system and subsystem. Then filter the Production efficiency column to find the area with the highest optimization potential. You can use options under the Production deviations column for further filtering; for instance, only show ongoing detected deviations with a volume above 10%.
# Deep dive view
Use the Deep dive page to analyze individual systems or wells, and resolve identified production deviations. When you want to dive into the nitty-gritty details, use the link to Cognite Charts (opens new window), where you can further explore, trend, troubleshoot, and perform root cause analysis of data and deviations and share the findings with your co-workers.
# General settings
# Search and filter
Find and explore wells, subsystems, or systems from anywhere with the Search field in the System selector pane located to the left in a BestDay view. You can use both letters and numbers in the search, and the results are filtered according to asset.
# Collect favorite wells
Group your favorite wells into a Collection for easy access.
Click Collections in the System selector to open the Add new collection window.
Give a unique and descriptive name of the collection.
Add the wells you want to have as favorites.
Click Create new collection.
You can also add wells to an existing collection from the Well Summary page by clicking the Watch icon on each row.
# Set preferred units
Set your preferred measurement and time units for all hydrocarbon liquid and hydrocarbon gas values throughout BestDay on the Profile page. BestDay uses two decimal digits as standard but if you need even more accuracy, hover over a field where the tooltip displays four decimal digits.
# Export data
Sort all data displayed and produced in BestDay with the Export button available from all views into a sorted spreadsheet. Set the date range (recommended max. 1 year) and select the data you want to export, such as production data, deferments, deviations, and BestDay predictions. The exported .cvs files are sorted by date and show each data point with all decimals per product. The standard layout conforms to other tools' typical input format and makes it easy to analyze further the data in other tools, such as MS Excel and PowerBI.
