Carbon dioxide injection to boost Adma-Opco oil fields
If the Abu Dhabi Emirate is rich of oil reserves, it has always been short of gas.
This lack of gas is partly compensated by the Dolphin pipeline carrying natural gas from Qatar to Abu Dhabi then to export.
In addition, Adnoc is planning to boost oil production to 3.5 million b/d by 2017, from actual 2.8 million b/d.
In this context, Adnoc is for years looking for solutions to reduce the oil industry consumption of 5 billion cf/d of natural gas to compensate the depletion of the maturing oil fields.
This solution may come from injecting carbon dioxide instead of natural gas into its offshore fields for enhance oil recovery (EOR).
Abu Dhabi Co. for Onshore Oil Operations (ADCO), the ADNOC‘s subsidiary for onshore operations has completed a pilot project onshore to inject 1.2 million cf/d carbone dioxide into the Rumaitha field.
First results are very encouraging to the point that ADCO is now planning a further four to five pilot onshore projects for 2013 and 2014.
This expansion on the Rumaitha field would require 20 or 30 times more CO² and would increase the oil recovery by10 percent.
At ADCO level the use of the CO2 injection to all the onshore fields would add 7 billion b/d, twice more than the actual crude oil production.
This overall expansion of CO² injection to all ADCO oil fields would require the production of 400 million to 500 million cf/d carbon dioxide.
At that point, in 2020 the question comes to find sustainable source of CO² to support such an EOR program.
From financial perspective, the current production costs are about:
– $5 a barrel for the carbon capture
– $20 a barrel all costs included with the CO2 injection.
Compared with oil barrel price staying steadily around $100, the pilot projects are proving that the carbon capture and injection is wealthy enough onshore to be tested offshore.
Masdar to provide ADNOC Carbon Capture expertise
Masdar Carbon, one of the five integrated units of Masdar, and ADNOC have decided to extend their agreement for closer co-operation in carbon capture usage and storage (CCUS).
One plan under consideration is to build a plant next to Emirates Steel Industries PJSC (Emirates Steel) to capture 800,000 t/y of CO².
From the significant progress made on the EOR pilot projects after two years in operation, ADNOC and Masdar have decided to move to the next step in drafting Head of Terms (HoT) to govern future detailed delivery agreements.
A CO2 injection pilot project on enhanced oil recovery (EOR) at an onshore field completed two years last November and the wealth of data collected over the period has encouraged the two partners to go ahead with the Emirates Steel project.
Masdar intends to capture nearly 800,000 t/y carbon dioxide-rich stream, prior to emission from the Emirates Steel Phase 1 and Phase 2 lines.
The CO2 feedstock from the Emirates Steel plant, containing 90% CO2, will be transferred to a common compression and dehydration facility at the project site in Mussafah.
The CO2 feedstock will be compressed into dense phase; delivering a CO2 feedstock of over 98% purity, through 50km of the pipeline network, to be injected in ADCO onshore oil field.
On the side of Emirates Steel, the partnership with Masdar would contribute to produce steel with lower carbon footprint through capturing carbon dioxide on a mass scale.
Successful carbon capture projects are anticipated to have a positive long-term economic impact on Abu Dhabi including economic growth, job creation and the development and export of CCS-related technology know-how.
Masdar in brief
Masdar is a wholly owned subsidiary of the Abu Dhabi Government-owned Mubadala Development Company, a catalyst for the economic diversification of the Emirate.
Established in 2006, Masdar is a commercially driven enterprise that operates to reach the broad boundaries of the renewable energy and sustainable technologies industry – there by giving it the necessary scope to meet these challenges.
Masdar Carbon provides technical assistance, project management, carbon trading expertise in oil and gas and power sectors in Middle East, Africa and Asia.
Masdar leads global advanced technologies, value chain applications and deployment strategies for clean energy and CCS.
Through this carbon capture and injection for enhanced oil recovery, ADNOC, Masdar and Emirates Steel are building up their respective Market Leadership and are proving how technology in the oil or steel industry can also cope with environmental benefits.
