Rock Creek

High pressure equipment has been designed to measure foam mobilities in porous rocks. Simultaneous flow of dense C02 and surfactant solution was established in core samples. The experimental condition of dense CO2 was above critical pressure but below critical temperature. Steady-state CC -foam mobility measurements were carried out with three core samples. Rock Creek sandstone was initially used to measure CO2-foam mobility. Thereafter, extensive further studies have been made with Baker dolomite and Berea sandstone to study the effect of rock permeability. 

Effect of Rock Permeability. The effect of rock permeability has been investigated by comparison of mobility measurements made with Baker dolomite and Berea sandstone. Mobility measurements carried out with Rock Creek sandstone (from the Big Injun formation in Roane County, W.Va) is also reported. Rock Creek sandstone has a permeability of 14.8 md. A direct comparison was made with Berea sandstone and Baker dolomite measured with 0.1% AEGS. As mentioned in an earlier section, the permeability of Baker dolomite (a quarried carbonate rock of rather uniform texture with microscopic vugs distributed throughout) was 6.09 md, and of Berea sandstone was 305 md. The single phase permeabilities were measured with 1% brine solution.

The experience from Rock Creek and Siggins Field suggests that tests may be substantially more informative if maximum use of pressure tests and multiple tracers is made to determine reservoir flow patterns before a site is selected and a test is designed, instead of being used as part of the test after a site has been selected.

Clean Water Services in Portland has developed a significant prc ram to optimize the use of digester gas as an opportunity fuel. They have evaluated IC engines, fuel cells, microtuibines, and gas turbines. Currently they are implementing a microtuibine project at the Durham plant, and system optimization at the Rock Creek plant [27]. 

FIGURE 6 Meteoric waters and creek runoff for White Rock Creek, a small drainage in Dallas County, TX. Note that the creek waters also lie close to meteoric water line and exhibit less variation. Shallow groundwater flow into the creek delivers a smoothed weighted average precipitation composition slightly modified by evaporation. Each local area has its own meteoric water line.

The manhole-cover assembly on the tank struck a rock the resulting rupture of the tank head caused propane to escape. There were woods on one side of the road on the other side a steeply rising embankment and trees and bushes, and then a steep dropoff to a creek.

High sulfidation (HS) deposits appear to be associated with a narrow range of igneous rock composition, dominated by dacite and andesite. Low sulfidation (LS) deposits are largely associated with andesite and rhyolite, but major deposits such as Ladolam, Porgera and Cripple Creek are associated with shoshonitic and alkalic rocks (Hedenquist et al., 1996).

Site 2 is situated on the south shore of Moore s pit (Figs. 1 2b). This site consists of i) a pyritic waste rock pile, covered with a thin veneer of Fe-oxide tailings and ii) a down stream acid drainage affected area that is characterized by a Fe oxide + sulfur-rich hard pan surface layer that overlies a stratified unit comprised of intensely altered (Fe-oxide stained) and unaltered Quaternary glaciolacustrine deposits. A small creek (product of beaver activities) flows along the eastern margin of the site into Moore s pond.

The study area is located within in the eastern tip of the Indian Mountain Deformed Zone, southeastern New Brunswick, Canada.

Abstract Nash creek is the largest Zn-Pb deposit in the Tobique-Chaleurs Zone, and contains indicated and inferred resources of 7.8 Mt grading 2.72% Zn, 0.55% Pb and 18.26 g/t Ag and 1.2 Mt grading 2.66% Zn, 0.52% Pb and 18 g/t Ag, respectively. The deposit is hosted by Early Devonian bimodal volcanic and minor interlayered sedimentary rocks that were deposited in a trans-pressional rift. The host rocks sequence includes the Archibald Settlement Formation (rhyolite flows domes and related rocks), and the Sunnyside Formation (mafic lava flows and interlayered volcaniclastic and sedimentary rocks). 

In the JRS the Dalhousie Group is divided into five formations (Walker and McCutcheon 1995). Only the upper three Archibald Settlement, Sunnyside and Big Hole Brook formations (described below), are exposed in the vicinity of Nash Creek. The Archibald Settlement Formation is the lowermost of these and consists of massive flows and domes of orange to red, aphyric, commonly flow-layered rhyolite. Up section massive flows are interlayered with fine- to coarse-grained volcaniclastic rocks including heterolithic lapilli-tuff and agglomerate, as-well-as volumetrically minor feldspar-phyric rhyodacite. A U/Pb zircon age of 415.6 +/-0.4 Ma has been returned from rhyolite of...
