the southeastern part of turkey is quite rich, fertile and mature in terms of hydrocarbonseepages. while the use of the related sources meet the energy demand, it damages the environment and humanhealth. in this study, several geochemical methods were applied to analyze the hydrocarbon sepage samplesobtained from seven towns in the province of adiyaman where is very close to the oil production ...

a meshless method namely, discrete least square method (dlsm), is presented in the paper for the solution of free surface seepage problem. in this method computational domain is discredited by some nodes and then the set of simultaneous equations are built using moving least square (mls) shape functions and least square technique. the proposed method does not need any background mesh therefore ...

Underground gas storage is the best choice for natural resource reserve and peak value. Storage capacity of underground single well injection production are key indicators shaving capacity. This paper focuses on research expansion stimulation a basin in Western China. Firstly, based study two-phase seepage law water, numerical simulation model coupling high velocity non-Darcy effect gas-water t...

for non-darcy flow in submerged porous media a one- dimensional mathematical model has been developed. rockfill detention dams are one of these porous media that comprised of relatively homogenous coarse rockfill which can be used to reduce flood discharge and hydrograph peak. in this research the focus was on the rockfill detention dams in submerged condition. the existence of overtopping rock...

In order to solve the engineering problem of increase in closure time or even failure frozen wall high-velocity permeable stratum, maldevelopment mechanism walls induced by high-flow-rate groundwater was studied a similar physical model test. The results show that flowing reduced heat transfer efficiency freezing pipes and changed spatial distribution area. non-uniformity coefficient thickness ...

Despite a number of studies in areas of focused methane seepage, the extent of transitional sediments of more diffuse methane seepage, and their influence upon biological communities is poorly understood. We investigated an area of reducing sediments with elevated levels of methane on the South Georgia margin around 250 m depth and report data from a series of geochemical and biological analyse...

Seepage meters were initially introduced as a viable field measurement tool for estimating fluid discharge from canal sediments by Israelson and Reeve (1944). Lee (1977) improved this device and demonstrated its utility in lakes and coastal marine systems. Since 1977, seepage meters have been used in marshes, lagoons, bays, rivers, and lakes with varying degrees of success (e.g., Shaw and Prepa...

Covered self-expanding metallic stents (cSEMSs) have emerged as effective treatment option for esophageal perforations. However, the large lower esophageal perforations where the cSEMS is placed across gastroesophageal junction have lower healing rates because refluxed gastric contents constantly irritate perforation and also there is increased risk of stent migration. Moreover, gastric mucosa ...

Synthetic Aperture Radar (SAR) technology has the ability to image surface oil seeps that originate by slow leakage from oiland gas-filled traps. Multi-temporal satellite data over such seeps delineate prospective areas and provide the locations for follow-up surface sampling from which key geochemical information of the reservoir oil can be obtained. Satellite radar can offer the oil industry ...
