# Forecast Scenarios
Forecast Scenarios are used to organize the process of production forecasting, decline curve analysis, and reserves reporting. A forecast scenario takes a well group as an input and applies user defined decline settings to build decline models for each fluid stream of the input wells. The overview page provides a starting point to dive into more detailed analysis. After building the forecast scenario, a user can view and edit each individual model in a single well view.
# Forecasting Approvals Workflow
Approvers | List of users with forecasting approval privileges. These users can approve or reject well forecasts but can not edit well forecasts.
Assignees | List of users with forecasting privileges. These users can create well forecasts but can not approve those forecasts.
|Approved||A submitted model that has completed the approval process. This model can no longer be edited.|
|Rejected||A submitted model that has been rejected by the approver. The assignees can edit this forecast and resubmit.|
|In Review||A submitted decline model that has yet to be approved or rejected by the approver. The assignee can no longer edit the model.|
|Working||A model that has been created and modified by the user.|
|Auto||A model that was auto-generated and has not been edited.|
|Initial||A model in the process of being generated.|
