RIO BLANCO OIL SHALE PROJECT--REVISED DETAILED DEVELOPMENT PLAN, TRACT C-A (V. 2, SECTIONS 2-5)

"In 1969, the U. S. Department of the Interior initiated planning for a prototype oil shale leasing program that eventually resulted in Gulf Oil Corporation and Standard Oil Company (Indiana) acquiring an oil shale lease for Tract C-a in the Perchance Creek basin of northwest Colorado. Gulf and Standard submitted the high bonus bid for Tract C-a ($210,305,600) at a lease sale in Denver on January 8, 1974. Rio Blanco Oil Shale Project (RBOSP), an organization directed and staffed by representatives of Gulf and Standard, was formed later that year for the purpose of developing the tract. RBOSP has conducted extensive geotechnical and environmental data  collection programs to establish baseline conditions on and around Tract C-a and to provide input for the selection of mining and processing plans. This revised Detailed Development Plan (DDP) describes RBOSP's proposed development and operation of a commercial-scale oil shale  complex and support facilities on and around Tract C-a. The development plan, environmental protection plans and environmental monitoring programs are based on the best technology presently available. Specific details of the engineering and environmental projections will change  because of continually improving technology in these areas. RBOSP will be flexible and responsive to changes in information and technology and will incorporate new information into the project plans wherever warranted.  Before RBOSP can proceed with development of Tract C-a, several approvals and permits must be obtained from County, State and Federal governments. Among these are approval of the DDP, and acquisition or necessary  rights-of-way and all permits for construction and operations, which presupposes the emissions and effluents from the from the operation will be  acceptable under State and Federal regulations."

RIO BLANCO OIL SHALE PROJECT--PROGRESS REPORT 9 (SUMMARY) ON TRACT C-A OIL SHALE DEVELOPMENT  (9/1/76-11/31/76)

The Geotechnical Data Gathering Project initiated by RBOSP on Tract C-a in the spring and summer of 1974 provides data required for engineering studies as well as data necessary to establish baseline conditions. The data gathering consists of specific tasks conducted under the geologic program and the hydraulic program. Previous RBOSP progress reports were organized to allow reporting of the ongoing activities of each task. Presently most of the major tasks under both the geologic and the hydrologic programs have been completed and consequently, the organization of the geotechnical data gathering portion of the Progress Reports has been restructured to include only those tasks in which activity was reported during the quarterly reporting period.

UNITED STATES OIL SHALE RESOURCES - AN ASSESSMENT OF ESTIMATE

The U.S. has large areas containing huge volumes of rocks witch fall under the definition of oil shale. These total in-place oil resources in oil shale have been estimated in a range of from 2.0 to 8.0 trillion barrels. Oil shale underlies about 20% of the U.S. land surface. Figure 1 shows the oil shale deposits in the U.S. including the major western tertiary Green River and the eastern black Devonian Formations and the other minor kerogen-bearing strata. Although oil shales are found as deep as 20,000 feet, the vast majority is located at much shallower depths of less than 5,000 feet. This oil resource is greater than all of the natural liquid oil that will ever be produced in the world. This paper will concentrate principally on potential oil shale resources as equivalent oil in-place on a gallons-per-ton (gpt) basis as determined by standard Fischer assay methods. Some authors have presented figures on recoverable resources based on a wide variety of production and economic factors. Such values are presented where available but their discussion is minimal. Most of the reports by the USGS on western and eastern oil shales describe the geology, geochemistry and types of resource but do not present estimates of the resource. On the other hand, a number of publications by the DOE, Laramie Energy Technology Center and its predecessor organizations, some private companies and some state agencies evaluate the resources with in-place oil resource figures.

MODELLING OF OIL SHALE PYROLYSIS IN A FLUID-BED RETORT

Pyrolysis of large oil shale particles in an isothermal fluid bed retort is theoretically studied in this paper. The governing equations describing diffusion and chemical reaction inside shale particles are solved analytically by using a finite Sturm-Liouville integral transform technique. The analysis gives not only the final distribution of products but also the dynamic response of these species from the onset of operation. Based on the information of the final product distribution (yield) and the dynamic response, the model solutions give guidance in choosing a proper temperature to operate the fluid bed retort for a given size of oil shale particle.

RIO BLANCO OIL SHALE PROJECT--DETAILED DEVELOPMENT PLAN, TRACT C-A (V. 2, SECTION 3, BASELINE CONDITIONS, BOOK 2 OF 2, CHAPTERS 7/14)

"In 1969, the U. S. Department of the Interior resulted in Gulf Oil Corporation and Standard Oil Company (Indiana) acquiring an oil shale lease for Tract C-a in the Piceance Creek basin of northwest Colorado. Gulf and Standard submitted the high bonus bid for Tract C-a ($210,305,600) at a lease sale in Denver on January 8, 1974. Rio Blanco Oil Shale Project (RBOSP) an organization directed an staffed by representatives of Gulf and Standard, was formed later that year for the purpose of developing Tract C-a. In the past two years, RBOSP has conducted extensive geotechnical and environmental  data collection programs designed to establish baseline conditions on and around Tract C-a and to provide input to engineering studies leading to the selection of mining and processing plans for Tract C-a development. This  4-vo1ume detailed development plan (DDP) describes the baseline conditions and RBOSP's proposed construction and operation of a commercial-scale oil shale complex and support facilities on and around Tract C-a. Three major requirements must be met before development operations on tract C-a can begin :  • The Area Oil Shale Supervisor, U.S. Geological Survey, must approve the development plan.  • Key Federal and State actions must be fulfilled and permits issued.  -The proposed development described in this plan must be commercially feasible at the time investments are committed."

ELECTRON PARAMAGNETIC RESONANCE AND THERMOGRAVIMETRIC INVESTIGATIONS OF THE PYROLYSIS OF EASTERN SHALES

The organic matter in oil shale is composed mostly of kerogen (insoluble in common organic solvents) with a few percent soluble bitumen. When Green River oil shale is heated to 573K, natural bitumen can be removed thermally from oil shale. The chromatogram of thermally separated bitumen is identical to that of the solvent-extracted bitumen (1). At temperatures above 573K, the kerogen decomposes to bitumen and subsequently bitumen to oil and gas (2,3). While considerable work has been done using Electron Paramagnetic Resonance (EPR) on coal (4,5) and western oil shale (6,7), relatively little is known about eastern shales. EPR measurements yield direct, in situ information on the kinetics of the organic-free radicals present in heated shale and natural bitumen. The present work was undertaken as a correlated EPR and TGA investigation of eastern shales to elucidate the pyrolysis mechanisms of these shales.

RIO BLANCO OIL SHALE COMPANY--SCOPE OF WORK, MODULAR DEVELOPMENT PHASE, ENVIRONMENTAL MONITORING PROGRAM, TRACT C-A OIL SHALE LEASE (REVISION)

"This scope of work describes the tasks that are being conducted to fulfills RBOSC's obligations to monitor selected environmental parameters during development of oil shale resources on Tract C-a in northwestern Colorado. The work scope described herein specifically covers a three year period as follows: Year 3 - Jan. - Dec. 1979 (12 months) Year 4 - Jan. - Dec. 1980 (12 months)  Year 5 - Jan. - Dec. 1981 (12 months)  This period represents the remainder of the Modular Development Phase (MDP) period. Although specific monitoring activities are described only for the MDP period, provisions for altering the program as development  proceeds are discussed throughout the scope-of work. Both short-term and long-range objectives are described along with contingency sampling and plans for long range trend analyses. The monitoring program described herein basically addresses the period during which RBOSC will be constructing MOP retorts and associated support facilities, through the ignition and burn of five in-situ (MDP)  retorts. The program is phased to allow certain aspects of the monitoring program to come on line as development progress dictates. The overall objectives of the RBOSC MDP Environmental Monitoring Program are to meet lease stipulations to conduct a monitoring program before and during development operations to provide a record of changes from conditions existing prior to development operations, a continuing check on compliance with lease provisions and a1l applicable Federal, State, and local environmental protection and pollution control  requirements; timely recognition and notice of detrimental effects, if any; and a factual basis for revision or amendment of the lease stipulations. The specific objectives within each discipline area are designed to contribute to the achievement of these overall objectives by providing data which will meet the lease stipulations and will satisfy the specific requirements communicated to RBOSC through the Area Oil Shale Office."

BX IN SITU OIL SHALE PROJECT, QUARTERLY TECHNICAL PROGRESS REPORT, JUNE 1, 1982 - SEPTEMBER, 1982

The Objective of this Project is to demonstrate the technical feasibility of using superheated steam as a heat-carrying medium to retort in situ the oil shale in the Green River Formation "leached zone" and provide a mechanism for the recovery of this shale oil with a minimum impact on the environment. Utilizing primarily the natural porosity in the "leached zone", approximately 450 billion BTU's of heat have been injected into a site over a 2-year period to heat to retorting temperatures a shale zone approximately 540 feet thick and covering about one acre. The Field Project is located at Equity's BX In Situ site in Rio Blanco County in Northwestern Colorado. The current activities at the Project are focused on maximizing the recovery of shale oil believed to be liberated by the steam injection process.

OUTLINE IDENTIFICATION OF OIL SHALE PARAMETERS FOR IN-SITU OIL SHALE GASIFICATION CONTROL PURPOSES

We report below the initial three months work on-line identification of oil shale parameters for the purpose of improved control of in-situ gasification of oil shale. Two approaches are described which may be complementary or alternative. The first approach employs special interrogation inputs for identification whereas the second approach uses the normal operational input to the gasification process. Both approaches yield sets of parameters which are subsequently employed in an oil shale properties classification algorithm to provide information for gasification control regarding the state of the gasification system, such as rubble size distribution, grade distribution, burn-front location and several electromagnetic properties of the zone considered.

RETORTING OIL SHALE AT HIGH TEMPERATURES, 2. SINGLE-VESSEL FLUIDIZED RETORT

The purpose of this project was to obtain information on the high-temperature retorting of oil shale in a single-vessel fluidized bed under conditions that would give maximum production of benzene. In order to obtain the necessary retorting temperatures of 1500supO to 18oosupO/F. with a two-vessel fluidized retort, a large recycle ratio of hot, burnt shale to raw shale feed would be needed. With a single vessel, there seemed to be the possibility that the coke on the spent shale could be burned in the lower part of the fluidized bed, thus supplying the heat needed to obtain the desired high retorting temperatures. At these temperatures, the rate of heating and retorting of pulverized shale is in the order of a second. This is a short enough time, supposedly, for the shale to be retorted in the upper part of the fluidized bed by contact with hot, burnt shale, before being carried by thermal solids circulation, into contact with oxygen in the entering fluidizing gas.
