The wells ...

Optimal groundwater contamination monitoring using pumping wells

by IWA Publishing  (Aug. 1, 2010)

This study presents a new method for selecting monitoring wells for optimal evaluation of groundwater quality. The basic approach of this work is motivated by difficulties in interpolating groundwater quality from information collected for only few sampled wells. The well selection relies on other existing data relevant to contaminant distribution ...

Falling Oil Price Forces Operators to Find Cost Savings in Water Management

by Biolargo, Inc.  (Nov. 20, 2015)

When oil prices were 80 to 100 dollars per barrel, water management costs were high, but they were tolerable when money was flowing profitably. However, as today’s falling price nears 40 dollars, water related costs are still high and only exacerbate widespread industry losses. The 150 US-based companies tracked by Oil & Gas Journal ...

In the following sections, we provide discussion and information to supplement the Feature Article. This material could not be included in the article itself due to space limitations of the printed ...

Multifunctional Well Implemented for In Situ Remediation of Hydrocarbon Contaminations in Soil and Groundwater

Abstract A recently developed Multifunctional Well has been implemented for the remediation of subsurface contamination caused by hydrocarbon spills. Four different remediation processes can be operated within the same well. At optimal efficiency of each remediation process, successive treatment of the capillary fringes, the vadose zone, and the ...
