ComboCurve: Unique Models

Overview

ComboCurve supports two types of economic models: Project Level Models and Unique Models. Understanding the difference between these two types is key to managing your assumptions effectively across scenarios and projects.



Unique Models vs Project Level Models

Project level models are created at the project level and can be assigned to any scenario within that same project. Unique models are assumption models that exist only for a specific well within a specific scenario. They are not shared across other wells in the scenario or across other scenarios.

Creating Unique Models

Unique models cannot be created from the general model menu. To create one:
  • Click the three-dot icon next to the specific well you want to assign the model to.
  • Select the assumption type (e.g., Ownership & Reversion).
  • In the model menu, toggle between Current Project Models and Unique Models using the bottom-left toggle.
  • Configure your model settings.
  • Click Save Unique (instead of Save As) to save the model as a unique model for that well and scenario only.

    • Note: The model menu will always display whichever model is currently assigned to the well at the top, regardless of whether it is a project or unique model.

    Creating Unique Models via CSV Import

    You can also create unique models in bulk through CSV import/export. Export first: Run a CSV export on the relevant assumption column. The export will include a Model Type column (project or unique) and a Model Name column, along with all corresponding model settings.

     Then to create unique models on import click the three dots again on the assumption and select CSV/Excel Import. 
    1. Option A – Generate All Unique Assumptions (checkbox)
      1. Check Generate All Unique Assumptions during import. ComboCurve will automatically create a new unique model for every well in the file, regardless of what is currently assigned. This will not remove or alter existing project level models or other unique models — it only adds new unique models.
    1. Option B – Manually specify unique models
      1. Leave the checkbox unchecked and manually change the Model Type column to unique for each well you want to assign a unique model to. Once a row is set to unique, you can freely edit the model settings for that well in the file.

    Note: Do not change the model name for any rows that will remain as project level models. If a project model name does not match an existing model in your project, you will receive an error on import.

    The New Qualifier Option - 
    1. Checked - Imports the changes into a brand new qualifier, leaving the existing qualifier intact.
    2. Unchecked - Overwrites the existing qualifier with the imported changes.

    Deleting Models

    As your project grows, you may accumulate a large number of unique or project level models. ComboCurve provides a bulk delete tool to help you clean up.
    Navigate to Project Settings and click the Delete Models icon.




    Select the assumption types and models type you want to delete:
    1. Assigned Unique – Unique models currently assigned to a well.
    2. Unassigned Unique – Unique models that exist in the project but are not currently assigned.
    3. Assigned Project – Project level models currently assigned to a well.
    4. Unassigned Project – Project level models that exist but are not currently assigned.

    Note: Deleting a model removes it from your project entirely. It will no longer be visible in any scenario. P-Series, Forecasts, Scheduling, Escalation, and Depreciation models are excluded from this delete tool.
    Recommended Use: If you want to clean up unique models without affecting your project level models, only check the unique model columns for the relevant assumption types.


    Video Walkthrough

    In this video, we look at unique models. Upon creation, unique models will only exist for one particular well in a single scenario. We also show how to import project-level models as unique and vice-versa. Below the video are some important reminders when importing economic models.




    NOTE:
    When importing economic models into a scenario, the headers that must be included in the file are: INPT ID, Incremental Index, Model Type, Model Name, and any of the model headers that are unique to a particular model (i.e. "WI %" in an Ownership and Reversion model, "Criteria" in a CAPEX model, etc.).
