Volcanic Episodes Near Yucca Mountain As Determined by Paleomagnetic Studies at Lathrop Wells, Crater Flat, and Sleeping Butte, Nevada
It has been suggested that mafic volcanism in the vicinity of Yucca Mountain, Nev., is both recent (20 ka) and a product of complex 'polycyclic' eruptions. This...
Instability in Granular Chute Flows
Numerical simulations showed that granular flows in a vertical chute can flow as a steady, uniform stream or as an intermittent slug flow. In numerical experiments slugs or grouping of...
Induced Subsidence: Environmental and Legal Implications
Subsidence of coastal areas can be induced by withdrawal of fluids from shallow, unconsolidated horizons beneath the shore zone. In southern California, Huntington Beach, Torrance/Redondo...
How Has the Joint Review Process Evolved?
The Joint Review Panel (JRP) process in California was established for offshore oil and gas-related coastal development projects to avoid duplication of effort among various permitting...
Oil-Spill Contingency Planning for OCS Operations
Oil-spill preparedness and response have been an important part of the Minerals Management Service (MMS) regulatory program since the Santa Barbara spill in 1969. The focus of the spill...
The Pacific Northwest OCS Task Force?Evolution and Status
The Pacific Northwest Outer Continental Shelf (OCS) Task Force was established in January of 1989 to provide advice to the Secretary of the Department of the Interior (DOI) on issues related...
Mitigation for Offshore Development/Fishing Conflicts
Three case studies, WestGold gold dredging offshore Nome, Alaska, Endicott Causeway off Alaska's North Slope, and Platform Irene offshore California, show that project related...
Onsite Compliance Programs for Major Oil and Gas Projects
Major oil and gas projects developed in Santa Barbara County are monitored for compliance with conditions of approval through various enforcement and compliance programs. the Resource...
Effective Mitigation of Air Emissions from OCS Sources
Unmitigated, platforms and associated facilities in the OCS typically emit large quantities of air pollution from power generation, drilling, transportation and other activities related...
Monitoring and Mitigating the Socioeconomic Impacts of Coastal Oil and Gas Development
Santa Barbara County has required that all companies engaged in major offshore oil and gas projects participate in a Socioeconomic Monitoring and Mitigation Program (SEMP). Yearly impact...
Chemical Composition, Physical Properties and Off-Site Migration of Municipal Landfill Gas
A sampling program of headspace gas from four monitoring wells and of off-site migration at three property line sites was conducted as part of a remedial design of a municipal landfill....
A New Power Invention
Hydropower is the most natural form of energy generated in the World. It allows us to make use of our natural resources without pollution. It harnesses the basic fundamentals of nature...
Slug Test: Double-Porosity, Linear Boundary, and Variable Storage Effects
The intention of this paper is to focus on three aspects of the slug test that are not as familiar as the main analysis techniques: the effects of double-porosity formations, the effects...
Prematurely Terminated Slug Tests?A Field Application
Slug tests suffer problems of non-uniqueness to a greater extent than other well tests. Alternatively, a prematurely terminated slug test (PTST) or a systematized drillstem test is proposed,...
Type Curves for a Slug Test in an Infinitely or Semi-infinitely Thick Aquifer
Type curves are provided for a slug test in an infinitely or semi-infinitely thick aquifer, the latter with the single confining layer immediately above or immediately below the well....
Well and Formation Losses
For design projects in the groundwater area, a step-drawdown test is commonly used to investigate the properties of the well-aquifer systems. Higher well and formation losses are usually...
Aquifer Measurements at Different Scales
Multilevel slug test data from five wells in a confined, sandy aquifer were analyzed to obtain an estimate of the vertical variation of the horizontal hydraulic conductivity, K(z). Hydraulic...
Agricultural Chemicals in Illinois' Rural Private Wells
A statewide sampling program was undertaken to define the extent of agricultural chemicals in rural, private drinking water wells in Illinois. A stratified random approach was taken for...
Nitrate in Rural Water Supplies in North Carolina
Over 9000 rural water supplies in North Carolina were analyzed for nitrate, chloride, electrical conductivity and pH. Data were collected on well characteristics and potential sources...
Automation of a Truck-Mounted Drill Rig
Truck-mounted drill rigs used for soils properties investigation, foundation evaluation, ore exploration, and producing monitor and water wells typically require, because of their weight,...
