ComboCurve: Custom Streams Workflow

ComboCurve: Custom Streams Workflow

Overview

This article presents a comprehensive workflow that encompasses the creation and utilization of custom streams. Specifically, it outlines the process of importing production data, running forecasts, and conducting economic analyses using these custom streams. For this case study, we have obtained monthly production data for oil, gas, water, and NGL from four wells in Midland. This method is applicable to various scenarios where custom streams are beneficial. The procedures detailed here are consistent across different use cases.

Workflow

Custom Stream Creation

Custom streams are categorized into two types: Company Custom Stream (CCS) and Project Custom Stream (PCS). For further differentiation, you may refer to the linked article. In this instance, we will establish a CCS named 'NGL'. Assuming appropriate permissions, you should navigate to the company-level page, select "Production Streams" under the "Custom Columns" tab, and then edit the name, units, and stream color as needed. After modifications, ensure to save the changes.


Data Import

With the custom stream activated, the next step involves importing production data for our wells. This can be done by navigating to the project where these wells are located, or by creating a new project for new wells. Data import is accessible via the side menu, where you should select 'Regular Import (.csv)'. It is crucial to ensure that the source scope and chosen ID match those of the existing wells if updating. During the mapping stage, you can link the NGL production data from your CSV to the NGL CCS. After completing the import, the NGL production volumes will be updated in the system.


Forecasting

Forecasting begins by creating a new forecast or using an existing one. Typically, only oil, gas, and water are visible by default. To include your custom streams, navigate to 'Forecast Options', select 'Stream Management', and add your streams for visualization and forecasting. Ensure that the stream is activated on the charts through the "Streams" dropdown. Now, the NGL production data should be visible on the chart. If it is not, verify the well assignments and data imports. Forecasts can be executed using the Auto Forecast engine, with settings adjusted according to best engineering practices.




Economics

After forecasting, proceed to economic analysis by setting up scenarios with the forecasted wells. This article focuses on economic models that necessitate additional steps for custom streams, such as Pricing Differentials and Expenses. In the Advanced View, add the NGL CCS line by clicking on "+ Key" and selecting the custom stream. Similar steps apply for adding differentials. Variable expenses can be linked to your custom stream accordingly.



Upon configuring the models in the scenario table, you can initiate the economic run. Prior to execution, you can configure the output settings to include values associated with your custom stream. Post-completion, results can be exported via predefined or custom CSV and PDF reports.
