Geothermal energy has been harnessed and used for domestic heating in Iceland. In wells that are typically drilled to a depth of 1,500 to 2,000 m, the temperature of the source water is 50 to 130 degrees C. The bottoms of the boreholes can therefore be regarded as subterranean hot springs and provide a unique opportunity to study the subterranean biosphere. Large volumes of geothermal fluid fro...

Arsenic concentrations were measured in 992 drinking water samples collected from New Hampshire households using online hydride generation ICP-MS. These randomly selected household water samples contain much less arsenic than those voluntarily submitted for analysis to the New Hampshire Department of Environmental Services (NHDES). Extrapolation of the voluntarily submitted sample set to all Ne...

Water-scarce areas can be identified from geology, meteorology, water installations, and drought conditions in the area. All of these aspects found Kulon Progo Regency. The aim this research is to identify scarcity Regency determine priorities for building up some deep wells. There are four parts method that used study, there geological aspect interpreted based on geological, hydrogeological, g...

Soil vapor extraction (SVE) systems are intended to cause substantial volumes of air to flow through the subsurface with the purpose of removing volatile contaminants. The effectiveness of SVE can be influenced by any effect that changes the specific gas capacity (discharge as a function of vacuum) of a well. Skins of low permeability material enveloping a well bore are widely recognized to aff...

About 15% of the U.S. population get their drinking and household water from a largely unmonitored source: private residential wells. About 400,000 new wells are drilled every year. A new USGS study suggests that the water in a small percentage of domestic wells could contain unsafe levels of volatile organic compounds (VOCs) [EHP 115:1539–1546; Rowe et al.]. VOCs come from a wide variety of so...

Abstract Few wells targeting high temperature, pressure intervals in most tertiary sedimentary basins have achieved their objective terms of technicalities and cost. Since shallow targets been drilled, exploration focus is drifting into deeper plays both onshore deep offshore areas. To ensure safe economic drilling campaigns, pore prediction methodologies used the region needs to be improved. T...

Abstract Affected by the surrounding injection and production wells, formation near infill adjustment well is in an abnormal pressure state, drilling completion operations are prone to complex situations accidents such as leakage overflow. The conventional shut-in method close all water wells around ensure safety of operation, but at same time reduce oil field production. This paper proposes a ...

Abstract In this work, the petrophysical properties of Abu Madi reservoir in El-Qara Field at northern Nile Delta Basin (NDB) were evaluated depending on well logging data two wells: El-Qara-2 and El-Qara-3. This evaluation revealed that well, promising gas zone is detected between depths 3315 3358 m, while El-Qara-3 best interval 3371 m. addition to production test parameters (gas rate, conden...

This research was sponsored by a grant from the Center for Rural Pennsylvania, a legislative agency of the Pennsylvania General Assembly. The Center for Rural Pennsylvania is a bipartisan, bicameral legislative agency that serves as a resource for rural policy within the Pennsylvania General Assembly. It was created in 1987 under Act 16, the Rural Revitalization Act, to promote and sustain the ...
