Geoscience/engineering characterization of the interwell environment in carbonate reservoirs based on outcrop analogs, Permian Basin, West Texas and New Mexico-stratigraphic hierarchy and cycle stacking facies distribution, and interwell-scale heterogeneity: Grayburg Formation, New Mexico. Final report

Description: The Grayburg Formation (middle Guadalupian) is a major producing interval in the Permian Basin and has yielded more than 2.5 billion barrels of oil in West Texas. Grayburg reservoirs have produced, on average, less than 30 percent of their original oil in place and are undergoing secondary and tertiary recovery. Efficient design of such enhanced recovery programs dictates improved geological models to better understand and predict reservoir heterogeneity imposed by depositional and diagenetic c… more

Increased Oil Production and Reserves Utilizing Secondary/Tertiary Recovery Techniques on Small Reservoirs in the Paradox Basin, Utah, Annual Report: 1996-1997

Description: The Paradox basin of Utah, Colorado, and Arizona contains nearly 100 small oil fields producing from carbonate buildups or mounds within the Pennsylvanian (Desmoinesian) Paradox Formation. These fields typically have one to four wells with primary production ranging from 700,000 to 2,000,000 barrels of oil per field at a 15 to 20% recovery rate. At least 200 million barrels of oil is at risk of being unrecovered in these small fields because of inefficient recovery practices and undrained heter… more

Establishment of an oil and gas database for increased recovery and characterization of oil and gas carbonate reservoir heterogeneity

Description: The objectives of this project are to augment the National Reservoir Database (TORIS database) and to increase our understanding of geologic heterogeneities that affect the recoveries of oil and gas from carbonate reservoirs in the State of Alabama and to identify those resources that are producible at moderate cost. These objectives will be achieved through detailed geological, engineering, and geostatistical characterization of typical Jurassic Smackover Formation hydrocarbon reservoirs in se… more

Reservoir characterization of the Smackover Formation in southwest Alabama

Description: The Upper Jurassic Smackover Formation is found in an arcuate belt in the subsurface from south Texas to panhandle Florida. The Smackover is the most prolific hydrocarbon-producing formation in Alabama and is an important hydrocarbon reservoir from Florida to Texas. In this report Smackover hydrocarbon reservoirs in southwest Alabama are described. Also, the nine enhanced- and improved-recovery projects that have been undertaken in the Smackover of Alabama are evaluated. The report concludes wi… more

Validation testing of the EERC pilot-scale circulating fluidized-bed combustor using Salt Creek coal

Description: The overall goal of the project was to provide a technical basis for assessing the economic and environmental feasibility of circulating fluidized-bed combustion (CFBC) technology, focusing on the effect of system configuration and coal properties on performance. Other underlying goals of the program were to (1) design and construct a CFBC test facility, thereby providing a test facility at an independent laboratory; (2) demonstrate that the test unit is capable of meeting the original design o… more

The kinetics of sulfation of calcium oxide

Description: The rate of sulfation of a CaO surface is rapid at first, limited by the intrinsic kinetics, but slows down with increasing conversion as a consequence of the increased resistance to diffusion through the product layer. The objectives of this study are to determine the intrinsic kinetics and the product layer diffusion pate by minimizing the resistances to gas-phase pore diffusion, and eliminating complications due to pore filling. This is achieved by the use of nonporous CaO. A wide range of p… more

Two-dimensional computer simulation of hypervelocity impact cratering: some preliminary results for Meteor Crater, Arizona

Description: A computational approach used for subsurface explosion cratering has been extended to hypervelocity impact cratering. Meteor (Barringer) Crater, Arizona, was selected for our first computer simulation because it was the most thoroughly studied. It is also an excellent example of a simple, bowl-shaped crater and is one of the youngest terrestrial impact craters. Shoemaker estimates that the impact occurred about 20,000 to 30,000 years ago (Roddy (1977)). Initial conditions for this calculation i… more

Predictive models of circulating fluidized bed combustors: SO[sub 2] sorption in the CFB loop

Description: The overall objective of this investigation is to develop experimentally verified models for circulating fluidized bed (CFB) combustors. Sorption of S0[sub 2] with calcined limestone was studied in a PYROFLOW type CFB loop at conditions approximating those found in a CFB combustor. Initially the CFB loop contained 150 micron CaO particles of a density of 3.3 g/cm[sup 3] and air at 1143[degrees]K and 3.25 atm. Atzero time, air containing 600 ppm SO[sub 2], was introduced into the riser bottom at… more

Valveless ash removal from pressurized fluidized-bed combustion systems by gravel bucket

Description: The objective of this project is to apply the gravel bucket pressure letdown concept to a stream of hot, gas-borne ash, under conditions similar to those found in a pressurized fluidized-bed combustor, where the system pressure is dissipated across a packed or partially fluidized bed of coarsely crushed rock. A second objective is to use the data collected during testing to develop a mathematical model which can be used to predict pressure drop in a gravel bucket device. The final objective of … more

Black shale studies in Kentucky. Quarterly report, October--December 1977

Description: During this quarter, most efforts were devoted to completing collection of field data from black-shale sections in order to meet a scheduled milestone at the end of December. Fourteen sections were described and measured, 12 from the outcrop belt on the eastern flank of the Cincinnati and two from the Pine Mountain outcrop belt. Five of Linda Provo's seven radioactive units were traced along the outcrop belts where possible. At the southern end of each outcrop belt, the units became increasingl… more

TOF (time-of-flight) measurements of pulsed neutrons for texture analysis of low symmetry materials

Description: The single crystal diffractometer at LANSCE, SCD, provides and ideal capability for the study of preferred orientation in geological samples by time-of flight (TOF) measurement of pulsed neutrons. The 2-d position sensitive neutron detector with the large wave length range allows one to measure the complete distribution of intensities for several poles very quickly. Each histogram covers about {pi}{sup 2}/16 radians of reciprocal space and contains information from all possible poles visible wi… more
