Solar enhanced oil recovery An in-country value assessment for Oman January 2014 Executive summary In 2012 the Sultanate of Oman (Oman) produced 920,000 barrels per day (bbl/d) of crude oil, ranking 21st in global oil production by country . It also produced 2.8 billion cubic feet (bcf) of natural gas, making it the 5th largest gas producer in the Middle East and the 26th largest in the world . 1 Solar EOR is likely to play an important role in the mix of EOR technologies. Instead of burning natural gas to produce steam, solar EOR involves the use of concentrating solar power (CSP) technology to produce steam. 2 Over the last ten years, due to the maturity of its has increasingly relied on enhanced oil recovery (EOR) technologies. Several techniques have been deployed, although thermal EOR, the focus of this report, dominates. The main thermal EOR technique entails burning natural gas to produce steam, which is injected into the reservoir to heat heavy oil and reduce its viscosity. The process increases both the rate of production and the amount of oil that can ultimately be recovered. concentrate sunlight onto receivers that collect solar energy and then convert it to heat. The heat is then used to produce steam from water. in 2012 that EOR would grow from 3% of current oil production to 25% of total liquids production by 2020. Solar EOR can generate the same quality and temperature of steam as natural gas . Therefore, the use of solar EOR could reduce demand for natural gas required for EOR, which can be re-directed to other economic activities such as power generation, water desalination and as feedstock and energy for industrial processes . 1 3 in EOR.

Ibid. Solar enhanced oil recovery An in-country value assessment for Oman Executive summary Deploying solar EOR could provide a hedge that reduces steam generated using solar energy is independent of the cost and availability of natural gas. Moreover, it also secures the long-term cost of steam once the system is installed since solar steam generators can produce at low operations cost5. with limited availability of natural gas, thereby providing a way to create and inject steam for EOR with no capital investment in gas infrastructure and allowing the development of many of Oman’s ‘stranded assets’. Moreover, owing to minimal operating expenses, use of solar EOR could enable producers to steam wells for a longer period of time compared to using gasof a reservoir. PDO began investigating solar steam generation in 2005 because of a recognition that EOR’s strategic importance to Oman was going to create a long-term We have also assumed that solar EOR accounts for varying proportions of this growth in thermal EOR production. The “Steady growth” scenario assumes solar EOR accounts for only 22% of the total thermal EOR by the end of the deployment period. The “Leadership” scenario assumes solar EOR accounts for half of total thermal EOR. In this scenario we assume that the Sultanate of Oman accelerates the deployment of solar EOR and targets industry leadership with potential export opportunities to other Gulf Cooperation Council (GCC) countries. The “Full-scale deployment” scenario assumes deployment that stretches the solar EOR technology to its technical limit, i.e., 80% of all thermal EOR coming from solar by the end of the deployment period. of solar EOR in Oman. tender process. This resulted in an award to GlassPoint Solar in August 2011 for the construction of a 7MWth The pilot has delivered its targets so far and large-scale deployment is contemplated. Oman currently uses 22% of its natural gas resources for EOR6. The continuous increase in domestic demand for natural gas makes the deployment of solar EOR technology an attractive economic proposition for the Sultanate of Oman. We have assessed the uptake of solar EOR under three alternative scenarios for 2014–23, analyzing the direct and indirect impact on jobs and economic value added. These scenarios assume that by 2020, approximately 35% of the total oil production in Oman, or 370,000 bbl/d will result from the deployment of thermal EOR technologies. This is in line with EOR production estimates from PDO, Occidental Petroleum Corporation (Oxy) and other industry stakeholders. 5 6 The installation of the solar EOR systems will have a direct effect on economic activity and job creation in the Omani manufacturing and services sectors. The amount of natural gas displaced due to the substitution by solar EOR technology could be re-injected into the economy. This can be done either by enabling alternative industrial projects or feeding other thermal EOR projects, thereby enabling the extraction of more oil. Alternatively, it could simply improve Oman’s balance of payments and enhance the Sultanate’s security of energy supply.

Other countries such as the United Arab Emirates (UAE) have taken this path with power station, a 100MW parabolic trough CSP plant. Saudi Arabia is also targeting a capacity of 25GW of CSP by 203212. By comparing gas savings per dollar of capital expenditure from the use of solar energy in power saves up to six times as much gas per unit of capital expenditure as saved by a CSP plant. Omani content, which will serve as a platform for the development of skills and innovation in the Sultanate. A large sustained deployment will expose local engineers to solar technology and its supply chain, enabling them to bridge skills from the existing oil and gas base in Oman and to widen their expertise to skills applicable across a variety of sectors. Experience in solar technology would also transfer to other uses, e.g., power generation, desalination and process steam, creating a technologically cross-skilled local workforce. Deployment of solar technology also provides scope for global leadership partnerships and through funding of research into different areas such as subsurface effects and behaviour of solar power-generated steam at rock model, lab and simulator levels; and understanding of the local environmental conditions and solar energy; as well as primary research on materials, durability of equipment and construction methods. Technical and commercial leadership in solar EOR could also allow Oman to tap regional and global export opportunities likely to open up in the next decade. Although the volume of EOR production in the Gulf Cooperation Council (GCC) countries outside of Oman is currently minuscule, EOR potential is estimated at 475 billion barrels of oil13 this opportunity will be thermal EOR, for which solar EOR is likely to compete. The most likely immediate 12 13 6 steam injection project led by Chevron that is under injection is expected to begin in 2017 and to produce up to 80,000 bbl/d with subsequent phases boosting production to more than 500,000 bbl/d. The expected thermal EOR production in this project alone is almost comparable to Oman’s current EOR production and may provide an immediate export opportunity. Substitution of natural gas by solar EOR will contribute to reduction in emissions of CO2 and other polluting agents. Considering the volume of natural gas saved and the average emissions from burning natural gas, we estimate emission abatement of 8.1 million tons of CO2 on an annual basis in the leadership deployment scenario when the systems are fully deployed. In addition, the technology currently deployed in the pilot project by GlassPoint and PDO does not have the environmental costs normally associated with large CSP systems such as consumption of large quantities of water. Moreover, the ecological and visual impacts due to large land footprint typically caused by CSP is also limited due to the relative compactness of the technology (three times less acreage compared to standard parabolic systems) but also because At a macro level, solar EOR will improve both shortterm and long-term energy security for Oman. It will reduce long-term risk of scarcity of gas, if deployed Natural Gas (LNG) cargoes which are subject to sudden short-term changes in availability and costs. Given Oman’s growing dependence on natural gas and its USD 60 billion LNG deal with Iran for the next 25 years, both its long-term and short-term security of energy supply require consideration. Use of solar EOR carries obvious advantages in terms of security of energy supply for Oman as it limits exposure to imports and frees up natural gas for other uses in Oman’s industrial sectors, thereby reducing the risk inherent in reliance on Iran KA-CARE, Saudi Arabia’s Renewable Energy Strategy and Solar Energy Deployment.
