|Clean and Secure Energy from Domestic Oil Shale and Oil Sands Resources||Last Reviewed 6/5/2013|
The Institute for Clean and Secure Energy (ICSE) is pursuing research to improve industry?s ability to utilize the vast energy stored in domestic oil shale and oil sands resources in a manner that will minimize environmental impact and effectively capture the combustion CO2 from production, upgrading, and refining of the produced liquid fuel. The objective of this research is to create models and simulation tools that can be applied to all in situ thermal processes. Practitioners can then use these tools to evaluate various recovery strategies and optimize their processes for energy and environmental efficiency.

In today?s environment, oil shale/oil sands development faces numerous technical, environmental, and legal challenges. Research to address these complex issues is necessary for the promotion of a viable commercial industry for liquid fuel production from oil shale/sands. The ICSE technical research program is organized around the theme of validation and uncertainty quantification through tightly coupled simulation and experimental design integrated with the legal, environmental, economic, and policy assessments required to achieve the dual goals of clean and secure energy from domestic oil sands and oil shale resources.
The research targets include:
This research will support and may accelerate the cost-effective and environmentally safe development of the nation?s domestic oil sands/oil shale industry for production of secure liquid fuels.
This validation research brings together multi-scale experimental measurements?from molecular scale through pore scale and, ultimately, reservoir or basin scale computer simulations?to enhance our understanding of the geology and in situ processing parameters controlling efficient production of oil shale and oil sands resources. Knowledge gained from this research will apply to most, if not all, industry processes and, in particular, those processes that utilize in situ methods for resource recovery. In situ recovery techniques are the primary focus of this research because of their potential for reducing the environmental footprint of oil shale/sands development.
Research focused on processing oil shale and oil sands will be integrated with research addressing the legal, policy, and environmental framework surrounding development of oil shale and oil sands in the western basins and, in particular, those resources within the Uinta Basin in Utah.
Phase II research accomplishments:
Research and analyses on three different sections of the Skyline 16 core [Uintah County, Utah, T11S, R25E, Sec. 9, UTM E 661444, UTM N 4415107 (NAD83)] obtained in May 2010 have been the focus of several project tasks. Thermogravimetric analysis (TGA) experiments on several small cored subsamples and powdered samples of the Skyline 16 core have been completed and core samples have been examined using 3-D multi-scale x-ray tomography to understand pore-scale transport processes of oil shale pyrolysis. Pressurized and atmospheric thermogravimetric analysis experiments on pulverized core samples have been completed and analyzed to determine product bulk properties and composition. Condensable pyrolysis products have been collected and analyzed in a gas chromatograph/mass spectrometer (GC/MS) for identification of the major components. Additionally, an N-S cross section of the Green River Formation using data acquired from the Skyline 16 core has been completed. This cross section complements the E-W section map completed during Phase I, and together they represent the first-ever complete cross-section description of the Uinta Basin.
The ICSE used the commercial software Star-CCM+ to develop a high performance computing computational fluid dynamics (CFD)-based simulation tool to study thermal heating of oil shale inside the ECOSHALE capsule developed by Red Leaf Resources. ICSE researchers have completed first generation simulations of the American Shale Oil (AMSO) rubblized bed. This effort included development of the computational domain of a characteristic section of the heater using discrete element methods, CFD, and thermal analysis. Computed heat distribution inside the test section was compared to experimental results and the findings were presented at the 32nd Oil Shale Symposium in Golden, CO in October 2012.
Topical reports and manuscripts completed during Phase II include:
Phase I research accomplishments:
Current Status (June 2013)
Current research is focused on combining university research with industry processing requirements, thereby scaling up the research for direct benefit to commercial development of oil shale/sands resources. Toward this end, the University of Utah is collaborating with AMSO, who in early 2012 announced they would begin testing their proprietary in situ oil shale production process. Current research is focused on improving the geometric representation of the process by incorporating depth and temperature-varying properties that closely describe the shale formation at the AMSO site. Recently, ICSE researchers increased the range of thermal conductivities for the study and continue to run simulations based on the January 2012 heater experiment test conducted by AMSO near Rifle, CO. These simulations are designed to help researchers better understand the effect of changing properties on the thermal history of the shale formation and on the thermal response recorded by the tomography wells. In addition, researchers have included modified properties for the specific heat variations based not as a function of temperature but, rather, of the oil shale grade. Team members have implemented these changes into their models and are provided weekly feedback from AMSO on their simulation results. .As a result, these simulations are expected to provide a very close representation of the actual AMSO experiment and will help AMSO scientists evaluate and better understand their experimental process.
ICSE researchers and staff are also nearing completion of the Oil Shale and Oil Sands Market Assessment. This document will provide a review of the current legal and regulatory framework to which oil shale/sands development efforts in Utah must adhere in order to be viable as well as assess the economics of four development scenarios: in situ and ex situ for both oil shale and oil sands. This comprehensive report as well as a companion report summarizing the Canadian oil sands experience are currently under review and expected to be available in June 2013.
