TAR SAND EXTRACTION BY STEAM STIMULATION AND STEAM DRIVE: MEASUREMENT OF PHYSICAL PROPERTIES (FINAL REPORT, 6/1/81-10/31/82)

"Measurements of thermophysical properties of Utah tar sands have been performed at the University of Wyoming, with support from the Department of Energy under Contract DE-AS20-81LC10534. Emphasis has been placed on measurements of relative permeability, specific heat, thermal conductivity and thermal diffusivity.  The present report discusses results of measurements of specific heat (sand matrix and bitumen), thermal conductivity and thermal diffusivity of N.W. Asphalt Ridge, Utah tar sand. Thermal diffusivity is found to decrease with temperature almost linearly, with a sample-to-sample variation of plus or minus 10%. Over the same range, thermal conductivity remains a constant to plus or minus 5%, but is sample-specific, with variations of between 1.2 to 1.8 w/m degrees K.  An apparatus designed to examine the details of two phase flow in porous media has been designed, built and tested. A description of the apparatus and some preliminary results are also discussed in this report."

DESIGN OF A FIELD EXPERIMENT FOR AIR-STEAM CO-INJECTION FOR OIL RECOVERY IN A UTAH TAR SAND

This paper presents the design of the US-DOE Laramie Energy Technology Center’s projects TS-4 which involve both in-situ reverse combustion and steam flooding, using a numerical simulator. The simulator showed that the combustion could be limited and contained in a middle 10-foot interval with a correlatable high permeability streak within the 65-foot pay zone of the upper Rimrock tar sand formation in Northwest Asphalt Ridge, Ulntah County, Utah. A high transmissibility path was assumed to obtain adequate injectivity and sustain a stable reverse combustion. Combustion ‘echoes’ developed and the front changed into a forward mode as the formation pressure increased and at very low air-injection rates. Oil recovery was accelerated by pre-heating the formation with the combustion before steam flooding the entire sand.

STUDY OF SPONTANEOUS IGNITION OF (UTAH) TAR SANDS

The time required for spontaneous ignition of oil in a formation during air injection can be calculated. Two important considerations are necessary for this calculation; the rate of oxidation and the initial reservoir temperature. The rate of oxidation as a function of temperature can be measured in the laboratory. Measurements of this type were made in our laboratory in 1973. This report gives the results of these measurements, treatment of the data, and results of calculations of ignition times.

COMBUSTION PROCESSES IN IN SITU COAL GASIFICATION:  PHENOMENA, CONCEPTUAL MODELS AND RESEARCH STATUS:  PART II--ALTERNATIVES TO CONTINUUM WAVE DESCRIPTIONS & MODELING OF EXPLOITED REGION DEVELOPMENT

The status of modeling reverse combustion along coal fissures is reviewed in some depth. There is evidence that such propagation is highly sensitive to irregularities in the structural state of the coal. Under some circumstances radiative heat transfer can control the process. Exploited region development is classified into processes at non-permeative and permeative fire faces. At permeative fire faces forward combustion along fissures can enhance burnout and rubbelization. The paper is directed mainly at shrinking coals but problems with swelling coals are briefly discussed.

SIMULATION OF GROUNDWATER FLOW REGIMES IN A COAL SEAM WITH UCG CAVITIES USING A FINITE ELEMENT MODEL

This paper deals with the simulation of groundwater flow in a coal seam with several cavities created in it by successive UCG burns. This activity in the coal seam alters the natural groundwater flow regime and simulation of the changes can determine the extent of the alteration and how long it would take to return to pre-burn conditions.

UNDERGROUND COAL GASIFICATION AT HANNA, WYOMING

This paper presents the results from the first phase of the Hanna II experiment in which coal seam permeability was evaluated, pneumatic linking and linking via reverse combustion were studied, and in which a sustained gasification process was maintained between the two linked vertical wells. Air injection alone did not increase permeability to levels which would allow sustained gasification. Reverse combustion linking was determined to be a local, relatively low temperature process which advanced at a rate of 5 ft/day and produced a high permeability carbonized path.

WATER-INFLUX MODEL FOR UCG WITH SPALLING-ENHANCED DRYING

The development of a better understanding and a predictive model for water influx is pivotal in scaling up the linked vertical well UCG process, since water influx strongly affects gas quality. A water-influx model is developed here which incorporates radial permeation of water through the coal seam, and steam generation by spalling enhanced drying of the coal and overburden. This random spalling process which enhances drying by exposing fresh wet surface is described by a surface renewal model. A cavity-growth model

INTERPRETATION OF CHEMICAL AND PHYSICAL MEASUREMENTS FROM AN IN SITU COAL GASIFICATION EXPERIMENT

A second underground coal gasification experiment is being conducted at the Laramie Energy Research Center's field site near Hanna, Wyoming. This paper presents the results from the first phase of this Hanna II experiment in which coal seam permeability was evaluated, pneumatic linking and linking via reverse combustion were studied, and a sustained gasification process was maintained between the two linked vertical wells. Extensive in situ and surface process instrumentation have provided considerable information on the chemical and physical mechanisms involved in underground coal gasification. Air injection alone did not increase permeability to levels which would allow sustained gasification. Reverse combustion linking was determined  to be a local, relatively low temperature process which advanced at a 5 ft/day rate and produced a high permeability carbonized path.

SEDIMENTOLOGY OF THE LOWER WASATCH DEPOSITS AT THE HOE CREEK (UCG) SITE, POWDER RIVER BASIN, WYOMING

Overburden sediments at the Hoe Creek UCG site are part of the lower Wasatch Formation. These sediments were characterized in terms of lithology, geometry, mineralogy, and environments of deposition. Sandstones in the overburden were further characterized in terms of texture, diagenesis, and source areas. These characterizations are based on information obtained from post burn cores, gamma ray logs, measured sections, SEM analyses, x-ray diffraction analyses, thin section studies, coal analysis, and from isopach and sandstone isolith maps. This information was also used to determine parameters responsible for surface subsidence at the Hoe Creek III UCG site.

THE PERMEATION THEORY OF UNDERGROUND COAL GASIFICATION

The decline in production and the increase in price of natural gas has spurred new interest in alternate energy supplies. There are a number of viable choices both in terms of near terms and long term planning. Resources such as coal, oil shale, tar sands, nuclear energy, and solar energy immediately come to mind. Nuclear energy is already supplying a significant portion of electrical energy in some parts of the US but further research and development of the breeder reactor will have to be done for this resource to be utilized to its full potential. Most alternate energy sources, other than the direct combustion of coal, are still in their infancies of development.
