Weyburn II CO2 Storage Project

Project Type

CO2 Geological Storage Demonstration Project

Project Category

CO2-EOR

Project Status

Operational Large Scale Project

Project Overview

A commercial-scale project that will utilize CO2 for enhanced oil recovery at a Canadian oil field.

Project Aim(s)

To assess the technical and economic feasibility of geological storage of CO2 in oil reservoirs and develop implementation guidelines for such projects and identify the risks associated with this method of CO2 storage, especially long-term risks of leakage.

Overall Project Costs

$20.5 million cash and $20.5 million in-kind (CDN funds) (Phase I only)

Project Timescale

Started in 2005 and is expected to finish by 2011. (This first phase lasted from 2000 to 2004. This final phase of the Weburn-Midale CO2 Project (see Project Summary, below) follows on from the initial phase).

Expected Key Deliverables

Completion of a design and operating manual aimed at site assessment, project design, and field implementation of commercial CO2 geological storage projects.

Project Summary

The Weyburn II CO2 Storage Project is also known as the final phase (phase II) of the Weyburn-Midale CO2 Project. This is the world’s first CO2 measuring, monitoring and verification initiative, and is a US $80 million project which was launched in 2000. This is a commercial-scale project that will utilize CO2 for enhanced oil recovery at a Canadian oil field. The first phase began in 2000 and is scheduled to conclude in June 2004. Phase II will involve transport of 95 million cubic feet per day of 95% pure CO2 from a North Dakota coal gasification facility through a 320-kilometer pipeline to an oil field in southern Saskatchewan, where it will be injected into the field for enhanced oil recovery.

Phase I of the Weyburn-Midale CO2 Project (see Weyburn CO2 Monitoring Project ) lasted from 2000 to 2004. This final phase started in 2005 and is expected to last until 2011. It involves building a comprehensive understanding of CO2 storage by monitoring CO2 being stored at EnCana’s Weyburn Field and Apache’s Midale Field.

The Weyburn Unit has a field size of 70 square miles, and yields medium sour crude oil. The amount of original oil in place (OOIP) is 1.4 billion barrels, and the projected amount of enhanced oil recovery (using CO2) is thought to be 155 million barrels. The projected amount of CO2 storage is estimated at over 30 million tonnes (gross), and over 26 million tonnes (net).

The Midale Field also yields medium sour crude oil. However, this is a smaller field, at 40 square miles, and its OOIP is approximately 515 million barrels. The projected amount of oil produced using CO2-EOR techniques is 67 million barrels, and the projected amount of CO2 storage is thought to be over 10 million tonnes (gross), and over 8.5 million tonnes (net).

The end deliverable of the Weyburn II CO2 Storage Project/final phase of the Weyburn-Midale CO2 Project will be a Best Practices Manual. This will include technical components (including site characterisation, monitoring and verification, wellbore integrity and performance assessment), and policy components (including regulatory issues, public communication and outreach, and business environment).

CSLF Endorsed Project.
The Carbon Sequestration Leadership Forum (CSLF) is an international climate change initiative that is focused on development of improved cost-effective technologies for the separation and capture of carbon dioxide for its transport and long-term safe storage.
The CSLF has endorsed 30 international CO2 Capture and Storage (CCS) projects as of October 2009.
