The Mesozoic Chang 8 Section in the Zhenjing area is a typical low permeability-tight sand reservoir and regarded as most important set of paybeds study area. Guided by principles basic geological theory, diagenetic evolution process hydrocarbon accumulation periods were determined through various techniques. More specifically, core observation, scanning electron microscopy (SEM), X-ray diffrac...

An integrated hydraulic fracturing followed by waterflooding was conducted in a heterogeneous sandstone formation the Northern Shanxi Slop of Ordos Basin Western China. Water breakthrough quickly occurred, and underlying mechanism water has not been well understood. Such needs to be investigated comprehensively from spatial connectivity multilayer sand bodies characterization hydraulic-natural ...

Abstract— In recent days the demand for river sand is increasing due to its lesser availability. Hence the practice of replacing river sand with M-Sand is taking a tremendous growth. It is also inferred from the literature that replacement of normal sand with M-Sand produces no appreciable increase in compressive strength due to the variation in the pore size of concrete at micro level. This pa...

Sediment deprivation from dam installments contributes to beach erosion yet the underlying physical and economic factors linking them together have traditionally been isolated during regional planning. In order to gain a better understanding of the behavior of a managed beach system, a dynamic simulation model was developed incorporating physical and monetary factors influencing the amount of a...

Abstract This study aims at the mineralogical and physicochemical characterization of clay formations Miocene age from Timgad Basin (Massif Aurès, NE Algeria), in order to evaluate their possible valorization, notably for potential use manufacturing bricks ceramic industry. For this purpose, four samples were taken a clay-dominated formation that outcrops 5 km east city. Each sample was collect...

Sandstorm has an effect on the electric field characteristics of outdoor insulator, and may result in flashover. The analysis of the electric field characteristic of insulator under sandstorm condition is very important. The electrostatic field finite element method (FEM) is used to calculate the electric field distribution along long rod insulator under sandstorm condition with FEM software. T...

As a water quality purification measure for areas such as lakes, a sand capping method by sand-upwelling system was developed. This method involves welling up clean sand from below contaminated sludge by using a water jet. The disposal of sludge and the acquirement of pure sand are not necessary like dredging and conventional sand capping works. Besides, the ecosystem will hardly be disturbed b...

Patients with acute myeloblastic leukemia (AML) with monosomy 7 are a group of patients with refractory AML who have a very poor prognosis. Therefore, rationally designed new therapies, including metronomic chemotherapy regimen with histidine deacetylase inhibitors (Valporic acid, ATRA) are being investigated as potential treatments for the population of refractory cases of AML. Herein, we repo...

An isolated, articulated, but crushed ossified lung of a mawsoniid coelacanth is reported from uppermost Cretaceous (upper Maastrichtian) Oued Zem, Morocco. The specimen the last record before their pseudo-extinction at end Mesozoic. also first marine in Mesozoic Morocco and occurrence coelacanths phospahte deposits North Africa. large size suggests fish estimated between 3.65 m 5.52 total body...
