models the water flooding of an oil reservoir [6]. Water flooding involves the injection of water, which is immiscible with oil, into certain wells of the reservoir to force oil out at others. In this case, s = s(x, t) is the saturation of water (i.e., the volume fraction of water in the total fluid, 0 < s d 1 ), and g= g(s) is the particle velocity of the water. Consequently, since the total v...
Seven crude oil samples recovered from wells of El Hamd and Bakr oil Fields locates in Egyptian central Gulf of Suez were subjected for Description, bulk composition of Maltene Fraction and hydrocarbons distribution. The Comparison of collected crude oils was achieved using Bulk parameters and Specific parameters, the first ones refer to properties of the whole sample such as API gravity, sulfu...
Many observational datasets of emissions, including emissions from the oil and gas sector, follow heavy-tailed distributions, for which a small fraction of the measured emitters are much larger than more typical emitters, and account for a large fraction of the total measured emission. Such distributions are problematic, because they are expected to exhibit large, negatively biased sampling err...
At present no company develops oil and gas fields without constructing geologic and hydrodynamic models. This is due in particular to the fact that recently the emphasis in design, planning and monitoring has shifted to overdissected and low-permeability reservoirs. To assess economic efficiency and optimal placement of wells and to predict hydrocarbon production levels, it is important to have...
Detecting the disappearance of active leks is the most efficient way to determine large declines in greater sage-grouse (Centrocercus urophasianus) populations; thus, understanding factors that influence lek abandonment is critical. We evaluated factors that may have influenced the probability of sage-grouse lek abandonment in the Bighorn Basin (BHB) of north-central Wyoming from 1980 to 2009. ...
Over the past ten years, unconventional gas and oil drilling (UGOD) has markedly expanded in the United States. Despite substantial increases in well drilling, the health consequences of UGOD toxicant exposure remain unclear. This study examines an association between wells and healthcare use by zip code from 2007 to 2011 in Pennsylvania. Inpatient discharge databases from the Pennsylvania Heal...
