Mercury species in natural gas condensate
… of ultra-trace levels of mercury in industrial gas and condensate streams is a cause of both environmental and production concern. The toxic nature of the element, in all forms, together with its ability to shut-down large processing plants dictates a need for its accurate and precise …

Gas-condensate flow modelling for shale gas reservoirs.
… and reshaping the landscape of the oil and gas global market. Gas-condensate reservoirs represent an important part of these resources. The key feature of these reservoirs is the condensate banking which reduces significantly the well deliverability when the condensate forms in the reservoir …

Management strategy of landfill leachate and landfill gas condensate
… treatability study was conducted for landfill gas (LFG) condensate. In a laboratory study, leachate samples were fractionated into humic acids (HA), fulvic acids (FA) and Hydrophilic (Hpi) fractions, the specific UV254 absorbance (SUVA254) of the three fractions follows: HA > FA > Hpi. However, …

Characterization of the exhaust gas condensate pH values of gasoline engines
Exhaust Gas Recirculation has been used in gasoline engines to reduce NOx formation and part-load throttle loss for many years. More recently, there is a trend towards down-sizing and turbocharging engines as the strategy helps to improve fuel economy. Cooled low pressure EGR complements …

A semi-empirical approach to modelling well deliverability in gas condensate reservoirs.
A critical issue in the development of gas condensate reservoirs is accurate prediction of well deliverability. In this investigation a procedure has been developed for accurate prediction of well production rates using semi-empirical approach. The use of state of the art fine grid numerical …

Effect of surfactants and brine salinity and composition on spreading, wettability and flow behavior in gas-condensate reservoirs
The well-known condensate blockage problem causes severe impairment of gas productivity as the flowing bottom-hole pressure falls below the dew point in gas-condensate reservoirs. Hence, this study attempts to investigate the concept of modifying the spreading coefficient and wettability using …

Continued optimization of a microelectrolysis treatment process for removal of arsenic from landfill gas condensate, characterization of materials, and evaluation of Fe as a predictor of treatment monitoring
Landfill gas condensate is formed during landfill gas (LFG) purification that must be carried out to produce pipeline-quality renewable natural gas. LFG condensates (LGC) are known to contain high levels of arsenic whose presence may result in exceeding applicable discharge limits. Arsenic …

Simulation of Multi-Component Gas Flow and Condensation in Marcellus Shale Reservoir
… 463 trillion cubic feet (Tcf) of recoverable gas in Pennsylvania and West Virginia, will play a critical role in providing clean energy, environmental sustainability, and increased security for our nation. However, due to recent low gas prices, most of the operating companies have slowed down …

Phase Equilibria in Systems Containing Hydrocarbon, Water and Methanol
… also stimulates production from retrograde gas condensate wells that show extensive productivity reduction because of near wellbore condensate buildup. The phase behavior of systems containing hydrocarbon, water and methanol was reviewed based on past experimental work. The main objective of …

Experimental Studies on Solvent Screening and Performance Analysis for Bitumen Recovery Using ES-SAGD
… candidates — Dimethyl Ether (DME), Natural Gas Condensate, Urea, and Pyrrolidine —to identify optimal concentrations that maximize recovery, minimize SOR, and reduce energy consumption. A series of ES-SAGD experiments was conducted using a fast-screening apparatus under controlled reservoir …

USING LANDSAT IMAGERY TO EVALUATE LANDSCAPE-LEVEL IMPACTS OF NATURAL GAS FIELD DEVELOPMENT: TAZOVSKY PENNINSULA, RUSSIA, 1984-2007
The Yamburg gas condensate field in northwestern Siberia sits atop the largest natural gas and petroleum basin in the world. Infrastructure related to the extraction and transport of natural gas is both geographically widespread, and has been shown to affect a much larger area than the immediate …

Atmospheric Mercury and Methane in the South-Central U.S.
… were analyzed. We found similar median levels of gaseous elemental mercury (GEM) as well as its seasonality at 11 sites. Seasonal and diurnal variations were also observed for gaseous oxidized mercury (GOM) and particulate bound mercury (PBM). This study also reports continuous measurements of …
