UGR: Drilling a Directionally Deviated Well to Stimulate Gas Production from a Marginal Reservoir in southern West Virginia

A brief discussion of some gas production experiments, done to better plan for future drilling events.

From the paper: "Numerous areas in both the western and eastern United States contain large reserves of gas trapped in very low permeable reservoirs. The Mesa Verde formation in the Piceance, Green River, and Uinta Basins of the Rocky Mountain region for example, contains reserves of trillions of cubic feet of gas. The Brown Shale of Upper Devonian Age in the eastern United States also holds tremendous reserves of natural gas. The Morgantown West Virginia Energy Research Center of the U.S. Energy Research and Development Agency formerly the U.S. Bureau of Mines, as nart of a long term earth fracture systems evaluation program, has concentrated on developing methods for more efficiently producing gas from these marginal reservoirs. As a result of these studies, ERDA and Columbia Gas Transmission Corporation cooperated on a program to drill a series of wells to test the deviated well concept in the economically marginal Upper Devonian gas reservoir."

UGR: Some Practical Considerations in X-Radiography

A paper about how X-Radiography works and how it could apply to 
natural gas extraction - particularly in the Devonian shales.

From the paper: "An X-radiograph is a photographic image of the preferential transmission (or absorption) of X-radiation by a solid object. The technique can supply an enormous amount of information with a minimal investment of time and money. However, obtaining high-quality, high-resolution radiographs requires a basic understanding of the process of radiography, and an optimization of a series of experimental parameters. This paper discusses the basic technique, discusses the experimental parameters and their relative effects, demonstrates the capabilities of X-radiography as an analytical technique, and includes an appendix of radiographs of Devonian shale material."

UGR: Natural Gas from Eastern U.S. Shales

A paper describing natural gas reserves in the eastern United States, how much may be obtainable, and how production would work.

From the paper: "A project has been Initiated by the Energy Research and Development Administration {ERDA) to characterize gas-bearing shale formations and develop improved gas-extraction technology for these lowpenneabl 11 ty "tight" reservol rs. The Eastern Devonian Shales are very prominent In this assessement, since they underlie a large section of the eastern and central portions of the United States. There Is considerable uncertainty In the magnitude of the hydrocarbon resource base since estimates range as high as 460,000 TCF {gas equivalents) In the Appalachian Basin alone; however, a recent estimate places the gas In place at 2,400 TCF. If only 10 percent of this latter figure were recovered, this would be enough natural gas to supply the eastern United States for 30 years at the current rate of consumption. Obviously, the potential payoff from the Eastern Shale is much greater If technology can be developed to increase the rate and amount of natural gas recovery. The primary reason why the natural gas has not been more fully exploited is that the wells that have been completed normally have low productivities, I.e., they produce at an average rate of 50,000 scf per day. By using advanced fracturing and stimulation methods, this rate may be increased two to four times. Fracturing results have been mixed since many new techniques have been tried. Massive Hydraulic Fracturing (MHF), foam, gas, dendrltic, and high yield explosives have already been tested with varying degrees of success or failure."

Solvent-refined-coal (SRC) process. Hydrodynamics and axial mixing in a three-phase bubble column

The hydrodynamics and the mixing properties in a 15.2 cm diameter x 335.3 cm high stainless steel column with three phases (air, water and coal) in cocurrent upflow were studied. The effect of solids particles size, solids concentration, slurry velocity and gas velocity on gas holdup and heat dispersion coefficients were determined. All the experimental data were correlated empirically and the results were compared with other published literature. Theoretical explanations of some results were provided

DEVELOPMENT OF TECHNIQUES FOR OPTIMIZING SELECTION AND COMPLETION OF WESTERN TIGHT GAS SANDS

The Phase I report pointed out the similarity between the fluvial Cretaceous Farrer Formation and the fluvial Cretaceous Cedar Mountain Formation in East Central Utah. The study also shows that a strong correlation exists between the vector sum azimuth, 8, of the small scale paleocurrent indicators and the long ax~s of these low sinuosity channel fill sandstones.
The Phase II report indicated that there was generally a difference in the characteristics of the small scale paleocurrent indicators between the fluvial Farrer beds and the Castlegate marine, the Sego marine marginal and the Wasatch (Green River) lacustrine and marginal lacustrine beds. It further indicated that paleocurrent direction indicators should be detected by high resolution geophysical logs.
The Phase III report presented a correlation of geophysical log, core and outcrop information from the GC-1 area in Grand County, Utah. Unfortunately, the correlation was more qualitative than quantitative and pointed out the need for upgrading the tools .
The Phase IV report extended the continuity studies previously made in the Western Piceance and Eastern Uinta Basins to the Green River and Wind River Basins of Wyoming. The continuity was found to be somewhat higher in the Wyoming basins, and low permeability microlayers much more prevalent as separators of the small scale sedimentary structural features.
The Phase V report summarized a characterization of some of the Cretaceous and Paleozoic fluvial beds in the Green River and Wind River Basins. Stochastic models of the permeability tensors of the characterized beds might be developed if additional data on the permeabilities of the thin low permeability separating layers can be obtained.
The Phase VI report presents the results of a detailed study of the Rifle Gap area in Colorado and makes a prognosis of the reservoir geometric characteristics of the fluvial Mesaverde target section at the U.S. Department of Energy multiwell experiment site. The prognosis is based on an extrapolation of the Rifle Gap study results 12 miles southwest to the multiwell area.

Low Interfacial Tension and Miscibility Studies for Surfactant Tertiary Oil Recovery Processes, Annual Report, December 1977-November 1978

The polarizing microscope was used to study the structure of aqueous solutions of petroleum sulfonates in the composition range planned for injection. All the surfactants studied showed a basic pattern of transformation between one structure and another over a relatively narrow range of salinities. As the salinity where this transformation occurs increases, so does the optimum salinity with a given oil, the condition of lowest interfacial tension. A polarized light box is being: developed to permit rapid determination of solution structure without the microscope since information on structure may be useful in the early stages -0f surfactant selection. Solutions containing a well-characterized surfactant, sodium dodecyl sulfate, were found to have the same basic structure pattern as the sulfonates. Hence, further experiments with this simple material should provide information relevant to the more complex petroleum sulfonates. The microscope was used to observe the dynamic contacting process between a surfactant solution and oil. Equilibration proceeds more rapidly at high salinities, mainly because of the spontaneous emulsification which occurs under these conditions. The ultracentrifuge was used to study microemulsions containing a conventional petroleum sulfonate. Results were similar to previous results for synthetic sulfonates except in a region where interfacial tension and solubilization results for the conventional sulfonate were anomalous. Progress was made in development of a theory to predict drop size in microemulsions, an important property influencing both phase behavior and interfacial tension.

Experimental evaluation of reservoir pretreatment in chemical flooding: final report

The purpose of this study has been twofold. First, by employing radial disks, the effect of flow geometry found in a field application has been incorporated into the experimental study. At the same time, the ultimate measure of preflush effectiveness, the incremental oil produced as a result of the pretreatment, has been chosen as the yardstick for comparison. Second, by combining the scope of several previously reported studies covering a few inorganic and organic preflush chemicals into one study with a single source of rock, the effect of substrate variability could be isolated from the analysis. This work in Berea is considered a foundation for similar studies to be compJeted in reservoir rock, where the effect of different clay compositions and rock heterogeneities can be compared to the standardized case with Berea sandstone.

Data requirements for EOR surfactant-polymer process simulation and analysis of El Dorado pilot-project simulation, Butler County, Kansas. Volume II. Appendices

The results of computer simulation of the El Dorado surfactant-polymer EOR pilot project, Butler County, Kansas indicated that conventional data from the project and other data in the public domain were not adequate for geologic, reservoir and process characterizations in a complex numerical simulation. As used by GURC in geologic characterization, and by INTERCOMP in process characterization and input into the CFTE simulator, the collective body of field and chemical data and related assumptions necessary for simulator input was not sufficient to predict how the chemical flood would behave in the Admire 650-foot sandstone reservoir. Based upon this study, a comprehensive body of data requirements for EOR simulation is defined in detail. Geologic characterization includes descriptors for rock, interwell and intrasystem correlations; reservoir characterization includes descriptors for fluid/rock, production, and flow rate properties; process characterization includes descriptors for chemical properties, interactions and functions. Reservoir heterogeneity is a principal problem in EOR simulation. It can be overcome within reasonable economic limits by successive orders of descriptors from: microscale (rock), achieved through borehole and core analyses; to macroscale (interwell), achieved through multiple borehole correlations; to megascale (intrasystem), achieved through extrapolation of rock and correlative well data into a generic depositional model that more »

Oil and Gas Exploration and Production in the State of Illinois

From the site: "A cells polygon feature class was created by the U. S. Geological Survey (USGS) to illustrate the degree of exploration, type of production, and distribution of production in the State of Illinois. Each cell represents a quarter-mile square of the land surface, and the cells are coded to represent whether the wells included within the cell are predominantly oil-producing, gas-producing, both oil and gas-producing, or the type of production of the wells located within the cell is unknown or dry. Data were retrieved from the Illinois State Geological Survey (ISGS) oil and gas wells database. Cells were developed as a graphic solution to overcome the problem of displaying proprietary well data. No proprietary data are displayed or included in the cell maps. The data are current as of 2006."

KY Coal Thickness Database

 This database contains data collected by KGS during field projects or compiled from reports prepared by other companies or agencies. The data in eastern Kentucky were primarily collected from roadcuts, natural outcrops, and coal mines and consist of single-point measurements of coal thickness. Some data in eastern Kentucky have been summarized from borehole records. The data in western Kentucky were primarily obtained from borehole records due to the lack of surface exposures. Therefore, duplicate information exists for western Kentucky data in the thickness database and the borehole database.    Thickness records are downloadable and include county, quadrangle, coal bed name, total coal thickness (coal only, inches), total parting thickness (if measured, inches), elevation (feet--relative to sea level), coal modifier (if available), exposure type, and location in coordinates (in UTM, State Plane, and Latitude/Longitude). Coal elevations reference the base of the seam and most were determined by altimeter. Coal bed names were assigned by field personnel during mapping; however, the user should use independent means to verify these results.    While the staff of the KGS has made every effort to ensure that the data reflects information on file, the Kentucky Geological Survey makes no warranty, expressed or implied, concerning the accuracy or validity of these data. The user assumes all liability for any losses or damages that may be incurred through any use or application of these data. Users are requested to notify KGS upon discovery of any errors in the data supplied.
