Carbon Capture and Storage
Carbon dioxide (CO2) generated from coal or gas-fired electricity power plants and other sources can be captured, transported and then stored underground in depleted oil and gas fields, saline aquifers, or unminable coal seams. Thus, it is not released to the atmosphere as a greenhouse gas. This process is known as carbon capture and storage (CCS).
Our commitment to CCS
There are multiple proof-of-concept carbon capture and sequestration projects ongoing and proposed around the world. Geological storage of CO2 will be required on a large scale to support CCS to reduce greenhouse gas emissions.
Our Reservoir Development Services group has global experience in evaluating and characterizing reservoirs for their suitability to store CO2. We also offer modeling and characterization services for enhanced oil recovery (EOR) using CO2. We have performed numerous basin-wide studies to identify potential CO2 sequestration sites. This reservoir expertise combines with Baker Hughes' formation evaluation and well construction expertise. Together, it’s a comprehensive resource for clients seeking dependable below ground storage solutions.
For many years, Baker Hughes has offered chemical products and services that enhance the capture process. We have pipeline management services for the safe transport of CO2 from the capture point to the injection site. Chemical treatments are used to control corrosion, scale, and other problems associated with CO2. Additionally, we supply CO2 injection pumps.
For EOR, injected CO2 maintains reservoir pressure and chemically frees up otherwise unmovable oil to enhance total production from pressure-depleted fields. A percentage of CO2 remains underground, but most is produced and recycled. Artificial lift offers state-of-the-art multiphase pumps for CO2 injection on EOR projects worldwide. Baker Hughes downhole tools have long been associated with the provision of corrosion-resistant completion systems in the CO2 arena.
This combined Baker Hughes CO2 experience will be invaluable to the industry as more pure storage projects are undertaken.
Rock Springs Uplift, Wyoming, US
One example of Baker Hughes CO2 involvement is happening in Wyoming. Working with the University of Wyoming, we have designed and are now drilling a deep characterization well. We’re gathering detailed geological data to determine CO2 storage capability in the Rock Springs Uplift, a deep, saline aquifer. Preliminary numerical simulation demonstrates that the trapping mechanisms of the aquifer could safely store 26 billion tons of CO2. This would accommodate Wyoming's CO2 emissions for 485 years at current output levels (54 million tons per year). Sequestration could, for example, offset emissions from the adjacent Jim Bridger Power Plant. The plant generates approximately 18 million tons of CO2 per year. Advanced Baker Hughes formation evaluation technologies and services will be used to fully assess the aquifer. It’s further envisioned that the saline water displaced by the CO2 could be treated to produce a valuable resource. This could be put to beneficial use. If this project proves suitable for CO2 storage, it’s expected to generate research and industry jobs, supporting the local economy.
