According to the grading curve and Water content allocation of hydrate reservoir, particle size distribution water condition formation sand are simulated, gas drive pressure difference is set. Under gravel packing control, one-dimensional unidirectional flow high argillaceous fine under analyzed, parameters such as displacement difference, rate, proportion permeability measured. The three phase...

Sand dripping in 1 dimensional Sand Pile Model is rst studied. Patterns and signals appear. Their behaviors and interactions are explained and asymptotic approximations are made. The total collapsing time of a single stack of sand is linear in function of the number of grains.

The Fuyu oil layer in a certain block is an ultra-low permeability layer. development scale of sand bodies the narrow, with rapid changes facies on plane, strong reservoir heterogeneity, and complex gas accumulation water distribution. Understanding flow mechanism can help improve effect this

bacground: the aim of this study was to determine the status of the cutaneous leishmaniasis in some nonendemic quarters in the city of isfahan, isfahan province, central iran. methods: a total of 16380 primary school students aged 6-17 years old and a total population of 2892 persons in 700 households in four nonendemic quarters were questioned and examined for the presence of ulcer or scar. sa...

The Klingnau reservoir, situated in north Switzerland, suffers from sedimentation in its left enlargement. The dam is placed in the Aare River about 1 km upstream of its confluence with the Rhine. Due to natural conservation and flood protection reasons, it has been sought for decades to slowdown the sedimentation process in the reservoir. For this purpose, 20’000 m3 of deposited material will ...

Sandstone intrusions are found in all sedimentary environments but have been reported most commonly from deep-water settings. They also appear to be more frequently developed in tectonically active settings where applied tectonic stresses facilitate development of high fluid pressures within the sediments. A variety of mechanisms have been cited as triggers for clastic intrusions. These include...

Leishmania (Leishmania) mexicana causes cutaneous leishmaniasis, an endemic zoonosis affecting a growing number of patients in the southeastern states of Mexico. Some foci are found in shade-grown cocoa and coffee plantations, or near perennial forests that provide rich breeding grounds for the sand fly vectors, but also harbor a variety of bat species that live off the abundant fruits provided...

Abstract This study aims to evaluate Kharita gas reservoir enhance the production. The increase in water-cut ratio reduces left hydrocarbons’ amount behind pipe. Accurate determination of pore throats, pores connectivity and fluid distribution are central elements improved description. integration core logging data responses is often used draw inferences about lithology, depositional sequences,...
