This report covers the electrical resistance tomography (ERT) work performed at the Hanford Reservation, 200 East Area Vadose test (Sisson and Lu) site during the period March 23 through May 5, 2001. The purposes of the ERT work were to: (1) compare and contrast the development of the highly concentrated sodium thio-sulfate plume (FY01 work) with the fresh river water plume observed during FY00; (2) use the resistance images to infer the dynamics of the plume during two or three of the sodium thiosulfate releases and during the water ''chaser'' release; (3) determine the influence of the site's steel casings on the capability to construct reliable ERT images; (4) determine if the steel casings at the site can be used as long electrodes to provide useful images of at least one release; and (5) develop quantitative estimates of the noise in the data and its effect on reconstructed images.

In 1998, Dallas Area Rapid Transit, a public transit agency in Dallas, Texas, began operating a large fleet of heavy-duty buses powered by liquefied natural gas. As part of a $16 million commitment to alternative fuels, DART operates 139 LNG buses serviced by two new LNG fueling stations.

The Blinebry (Permian) formation of eastern Lea County, NM has a long history of exploitation for petroleum and continues even today to be a strong target horizon for new drilling in the Permian Basin. Because of this long-standing interest it should be classified of strategic interest to domestic oil production; however, the formation has gained a reputation as a primary production target with limited to no flooding potential. In late May of 1999, a project to examine the feasibility of waterflooding the Blinebry formation was proposed to the U.S. Department of Energy's National Petroleum Technology Office (Tulsa, OK). A new well was proposed in one region (the South House area) to examine the reputation by acquiring core and borehole logging data for the collection of formation property data in order to conduct the waterflood evaluation. Notice of the DOE award was received on August 19, 1999 and the preparations for drilling, coring and logging were immediately made for a drilling start on 9/9/99. The Blinebry formation at 6000 feet, foot depth was reached on 9/16/99 and the coring of two 60 foot intervals of the Blinebry was completed on 9/19/99 with more than 98% core recovery. The well was drilled …

The unsaturated zone (UZ) in Miocene-age welded tuffs at Yucca Mountain, Nevada, is under consideration as a potential site for the construction of a high-level radioactive waste repository. Secondary calcite and silica minerals deposited on fractures and in cavities in the UZ tuffs are texturally, isotopically, and geochemically consistent with UZ deposition from meteoric water infiltrating at the surface and percolating through the UZ along fractures. Nonetheless, two-phase fluid inclusions with small and consistent vapor to liquid (V:L) ratios that yield consistent temperatures within samples and which range from about 35 to about 80 C between samples have led some to attribute these deposits to formation from upwelling hydrothermal waters. Geochronologic studies have shown that calcite and silica minerals began forming at least 10 Ma and continued to form into the Holocene. If their deposition were really from upwelling water flooding the UZ, it would draw into question the suitability of the site as a waste repository.

Yucca Mountain is under study as a potential site for underground storage of high-level radioactive waste, with the principle goal being the safe isolation of the waste from the accessible environment. This paper addresses the hydrogeologic characteristics of the fault zones at Yucca Mountain, focusing primarily on the central part of the mountain where the potential repository block is located.

The Jacksonburg-Stringtown oil field contained an estimated 88,500,000 barrels of oil in place, of which approximately 20,000,000 barrels were produced during primary recovery operations. A gas injection project, initiated in 1934, and a pilot waterflood, begun in 1981, yielded additional production from limited portions of the field. The pilot was successful enough to warrant development of a full-scale waterflood in 1990, involving approximately 8,900 acres in three units, with a target of 1,500 barrels of oil per acre recovery. Historical patterns of drilling and development within the field suggests that the Gordon reservoir is heterogeneous, and that detailed reservoir characterization is necessary for understanding well performance and addressing problems observed by the operators. The purpose of this work is to establish relationships among permeability, geophysical and other data by integrating geologic, geophysical and engineering data into an interdisciplinary quantification of reservoir heterogeneity as it relates to production. Conventional stratigraphic correlation and core description shows that the Gordon sandstone is composed of three parasequences, formed along the Late Devonian shoreline of the Appalachian Basin. The parasequences comprise five lithofacies, of which one includes reservoir sandstones. Pay sandstones were found to have permeabilities in core ranging from 10 to 200 mD, whereas …
