Low-permeability glutenite reservoir pattern deployment and optimization are important for its efficient development. In this paper, taking the in Sha 4 member of Yong1 as an example, numerical simulation method percolation theory used to study influence sediment source in-situ stress direction on well deployment. Then, low-permeability was optimized, finally optimized parameters designed. It i...

CASE A 53-year-old male sustained a high-pressure water injection injury to his foot while working in a river. He was taken to the operating room for emergent irrigation and debridement of copious riverbed sediment. Cultures taken from the operating room were positive for multiple anaerobes, fungus and mold and he was treated with appropriate antibiotics. To date, his only residual deficit is a...

Sediment samples from the coastal area of Asaluyeh harbor were collected during autumn and spring 2015. The acid-volatile sulfide (AVS) and simultaneously extracted metals (SEMs) were measured to assess the sediment quality and potential ecological risks. The average concentrations (and relative standard deviation (RSD)) of AVS in the industrial sediments were 12.32 μmol/g (36.91) and 6.34 μmol...

Studies about sediment erosion were mainly concentrated on the river channel sediment, the terrestrial sediment, and the underground sediment. The transport process of underground sediment is studied in the paper. The concept of the flush potential sediment is founded. The transport equation with stable saturated seepage is set up, and the relations between the flush potential sediment and wate...

Recent studies in our laboratory and others have demonstrated conclusively that polycyclic aromatic hydrocarbons (PAHs) and other unsubstituted aromatics are biodegradable under anaerobic conditions. This important result suggests that PAH contamination in anaerobic environments (such as sediments) may be more amenable to biological treatment than once thought. In previous work, we postulated t...

Abstract The forest road is most important sediment sours in the forest regions. the forest roads with remove vegetation cover and disorder hydraulic behavior regions, causes sediment product and problems due of sediment. This study has been done to surveying sediment factors roll in the sediment producing in the northern forest road. For this goal were selected purpose road sections by using h...

Sediment traps were used to evaluate the frequency, cause, and relative intensity of sediment mobility/resuspension along the fringing coral reef off southern Molokai (February 2000-May 2002). Two storms with high rainfall, floods, and exceptionally high waves resulted in sediment collection rates>1000 times higher than during non-storm periods, primarily because of sediment resuspension by wav...

Introduction: Cassiduloids play a prominent role in echinoid evolutionary history because they probably are the ancestral group of clypeasteroids. Some extant species brooding and rare environment. Consequently, there no studies on their maintenance laboratory. Objective: Establish an efficient aquarium system for C. mitis, endemic to Brazil, ontogenetic studies. Methods: Four systems were buil...

To inform cost-effective monitoring of offshore geological storage carbon dioxide (CO2), a unique field experiment, designed to simulate leakage CO2 from sub-seafloor reservoir, was carried out in the central North Sea. A total 675 kg were released into shallow sediments (?3 m below seafloor) for 11 days at flow rates between 6 and 143 d-1. set natural, inherent tracers (13C, 18O) injected adde...

The variable and complex nature of the sediment load of rivers has led that the estimation of sediment entering the reservoirs and the production of long term sediment, for determining the lifetime of the structures encounter with the problem. Application of sediment rating curves is one of the most common methods for estimating the suspended sediment load of rivers. Regardless of the accuracy ...
