Good morning Gentlemen it gives me great honor and pleasure to present to you Saudi Arabia’s effort in carbon management... Click .
Saudi Arabia has a strong history in Env protection and awareness: I will mention here three activities that we are doing to address the climate change 1…., 2…., 3…. The Association of Energy Engineers (AEE) presented Saudi Aramco with its Corporate Energy Management Award on Oct. 30 during AEE's 35th World Energy Engineering Congress in Atlanta, Georgia. The company received the award for its energy management program that in 2011 achieved an energy savings of about 10,000 barrels of oil equivalent per day, which represents 3.5 percent of the company's total energy consumption for the year. The program involved the implementation of 59 energy-saving initiatives.
Saudi Aramco has made great strides in CM… Formed a multidisciplinary team to address the issue of climate change Developed a CM Technology Roadmap We have been raising regional and industry awareness by Enhancing collaboration among National Oil Companies We organized the first regional symposium on carbon management (May 2006) We have had a strong external and internal engagement, and We have been active in conducting R&D studies to address CM issues. Some more material… Saudi Aramco has established a carbon management team for effectively managing challenges and opportunities of CO2 emissions. The team has established a road map with a clear strategy. This strategy targets creating a forward looking, broad base R&D programs that provide economically sound carbon management technological solutions, including the sequestration of CO2 and its potential use in enhancing recovery. It also aims to ensure that liquid petroleum products are environmentally friendly.
This is Saudi Arabia Carbon Management Technology Roadmap There are five focus area in this road map: ……………………….. I will go over these focus areas one by one.
05/30/13 The first focus area is CO2 Capture from Fixed Sources All the activities under this focus area will culminated in a pilot in one of our fixed sources, may be one of the gas plants.
05/30/13 The second focus area is CO2 Capture from Mobile Sources The transportation sector is a major source for CO2 and as part of the CO2 mitigation we would like to develop technologies that will capture the emitted CO2 from cars, marines and trains
The prototype vehicle shown here is the first-of-a-kind demonstration of onboard CO2 capture system designed by the R&D Center mobile carbon capture team. The prototype vehicle shown here was on display here in Dhahran earlier this year. At the heart of the CO2 capture system lies a novel sorbent formulation developed by R&DC in working with another research institution. Considering the extreme and dynamic mobile operating conditions, this sorbent material had to be devised to cope with the high-temperature/low-pressure exhaust conditions and have fast kinetics. The novel sorbent used in this prototype has the loading capacity of 20wt% at 325 o C and atmospheric pressure. The CO2 capture system consists of two sorbent beds one operating in adsorption mode and the other in the regeneration mode. The sorbent regeneration is performed using the heat from the exhaust gas and the CO2 released is compressed to about 100 bars and stored in a pressurized tank. Conceptually, the captured CO2 can be unloaded during refueling, and converted on-site to useful products or transported to central locations for conversion, sequestration or other uses such as EOR.

05/30/13 The third focus area is CO2 Industrial Application Utilize captured CO2 or carbon to maximize value of capture from combustion of fuels As you are aware before most of the car parts was made of steel and now most of its parts are from plastic and carbon fiber. Carbon fiber will make the body of the car or the airplane lighter and stronger. Now, several component of the giant Airbus plane use carbon fiber. As part of our activities to have win-win solution is to see and research how that CO2 will be converted to such materials
05/30/13 The fourth focus area is CO2 Storage In this focus area we want to develop technologies that will help us to monitor CO2 movement in aquifers and also to study the impact on long term storage of CO2 CO2 Storage: Established a new research initiative for CO2 storage to develop required technologies that will help to store CO2 in deep Saline aquifers. Conducting research on fundamental principles of CO2 geological storage. Drafted criteria for the selection of deep saline aquifers for sequestration. Screening Saudi Arabian potential dry structures for sequestration CO2. Sponsoring a CO2 storage research consortium: Gulf Coast Carbon Centre (GCCC), in the Bureau of Economic Geology, the University of Texas at Austin, USA.
05/30/13 The last but not least focus area is CO2-EOR As part of our activities is to develop a win-win approach and we want to develop technologies to address climate change and promote CCS technologies and in the same time increase our oil recovery factor. Saudi Arabia does not EOR at production scale for decades to come we are doing this to shoulder the efforts to mitigate CO2
The project will include CO2 capture, compression and dehydration facilities that will be installed at an existing gas plant. A high pressure pipeline will transport the captured CO2 to the injection manifold at the field. The source of CO2 is from the waste gas streams located at a gas plant. We plan to inject 40 million standard cubic feet of CO2 per day starting 2013. The CO2-EOR demonstration project will be assessed for three years to define the amount of CO2 sequestered.
The main project objectives are to sequester CO2 and address primary risks and uncertainties. An important aspect is to determine the migration of CO2 and measure sweep, both areally and vertically. We will be measuring the amount of Co2 injected and the amount of CO2 produced. From a material balance we can determine the amount of CO2 sequestered or stored. An added benefit also is to book additional reserves. These uncertainties will be monitored through a well developed Monitoring and Surveillance program.
In conclusion: … we are actively engaged internally and externally on climate change mitigation … our approach focuses on developing win-win technologies … we have developed a comprehensive technology roadmap on CO2 capture, sequestration and utilization … Our research program combines in-kingdom development and regional/international collaboration … the planned CO2-EOR demonstration project to be implemented in Saudi Arabia by 2013 … .to sequester CO2 into depleted reservoirs…
Good morning Gentlemen it gives me great honor and pleasure to present to you Saudi Arabia’s effort in carbon management... Click .
Very briefly I will give you a general background on the project … The CO 2 will be obtained from Hawiyah NGL plant, processed and piped to ‘Uthmaniyah where the actual project is located. Here is a zoom in into the project location ... So far we have drilled four producers, four injectors and one observation well. The second observation well was designed and will be drilled 1Q this year. The first observation well is open hole and the second will be with nonmetallic completions to allow for diffusion logs. The producers are now flowing to the GOSP. The injectors are tied-in. BTW we had this project peer-reviewed in Houston last year with the CO 2 -EOR experts and we have received positive feedback and some recommendations, which we incorporated in our plans.
We conducted hundreds of simulations to design this project but I will only show you the selected and the final one for the pilot. We will be injecting 40 MMscfd of CO 2 . There will be a row of injectors and a row of producers. CO 2 will be injected in a WAG mode or water-alternating-gas with 3 months CO 2 and 3 months of water injection. The well spacing is about 2,000 ft. The CO 2 will be injected into the first row of injectors and oil produced from the first row of producers. When these wells gas out, the producers could be converted into injectors and a set of three new producers can be drilled. This could continue in a progressive manner.
The main objective of the M&S program is to provide a clear assessment of CO 2 potential on both front: sequestration and EOR. The secondary objective is to capitalize on this opportunity to test new M&S technologies.
So we have divided our M&S activities into three parts: The first is field activities, which includes the drilling of the wells and baseline production testing to determine the IOR potential. The second is routine logging, coring, tracer tests and sampling. The third is emerging methods for CO 2 plume tracking … seismic, EM and gravity … and new CO 2 saturation and IWCTT tests.
This table lists M&S tools and technologies and compares how they fair in the parameters we are trying to evaluate. The parameters being: reservoir characterization, plume tracking, saturation monitoring, CO 2 leakage, and well integrity. The main points of this exercise are: Routine logs and cores work well near wellbore when they are applicable. Emerging technologies such as seismic, EM, and gravity will give more data deeper in the reservoir for characterization, plume tracking and saturation monitoring; however, there are challenges to be addressed when they are applied for CO 2 operations. And that’s the research components we are working on to stretch the envelop and make them applicable for CO 2 .
