In this study, anesthetic effects of five different concentrations of 2-phenoxyethanol (0.2, 0.3, 0.4, 0.5 and 0.6 ml/L) and clove oil (0.50, 0.75, 1.00, 1.25 and 1.50 ml/L) on rainbow trout (Oncorhynchus mykiss) were studied at temperatures 7, 13 and 18ºC. For this purpose, 900 fish (39.08 ± 1.13 g and 15.48 ± 0.21 cm) were used in the experiment. Induction time of 2-phenoxyethanol and clove o...

Fluorosurfactants are effective in a variety of Enhanced Oil Recovery (EOR) techniques including (i) improving subterranean wetting, (ii) increasing foam stability, and (iii) modifying the surface properties of the reservoir formation. While fluorosurfactants have been used in gas and oil exploration for four decades, the increased demand for petroleum and the greater understanding of the benef...

Reservoir wettability is determined by complex interface boundary conditions acting within the pore space of sedimentary rocks. These conditions have a dominant effect on interface movement and associated oil displacement. Wettability is a significant issue in multiphase flow problems ranging from oil migration from source rocks to such enhanced recovery processes as alkaline flooding or altern...

45 Oil spills from offshore drilling and coastal refineries often cause degradation of coastal wetlands that can 46 take a long time to recover. Early oil detection may prevent losses and speed up recovery if monitoring of 47 the initial oil extent, oil impact, and recovery are in place. Satellite imagery data can provide a cost48 effective alternative to expensive airborne imagery or labor int...

Steam injection is the most suitable of Enhanced Oil Recovery (EOR) methods to recover high viscosity oil. This is due to the capabilities of steam to reduce oil viscosity and increase the sweep capability of oil from the injection well toward the production well. Oil operating conditions in production should be match well with the operating condition target at the bottom of the production well...

Spontaneous imbibition is of special importance to oil recovery from fractured reservoirs. Laboratory measurements of volume of liquid imbibed versus time are often used in the prediction of oil recovery. Imbibition measurements also provide a useful approach to the complex problem of characterizing the wetting properties of porous media. Correlation of a large body of data for imbibition of br...

Fractional flow analysis confirms the advantages of surfactant alternative gas injection (SAG) in enhanced oil recovery, but an adsorption phenomenon that has been affected by several factors, weakens the effectiveness of SAG injection. In this study, the effects of sacrificial agent, gas phase, and surfactant concentration on adsorption density on silica mineral were investigated by static and...

April 20, 2010 marked the start of the British Petroleum Deepwater Horizon oil spill, the largest marine oil spill in US history, which contaminated coastal wetland ecosystems across the northern Gulf of Mexico. We used hyperspectral data from 2010 and 2011 to compare the impact of oil contamination and recovery of coastal wetland vegetation across three ecologically diverse sites: Barataria Ba...
