Abstract Aim This study aimed to evaluate land use, distribution of particle size fractions, organic matter (OM) and perform a metal quantification liable complexation in the Itupararanga Reservoir (São Paulo, Brazil). aquatic ecosystem is used for water supply energy generation constantly subjected anthropogenic impacts that alter its physical chemical characteristics. Methods In single campai...

Hydraulic fracturing is an important method of reservoir stimulation in the exploitation of geothermal resources, and conventional and unconventional oil and gas resources. In this article, hydraulic fracturing experiments with shale, sandstone cores (from southern Sichuan Basin), and granite cores (from Inner Mongolia) were conducted to investigate the different hydraulic fracture extension pa...

Offset-dependent characteristics of seismic scattering are useful in the interpretation of fractured reservoirs. Synthetic seismograms generated by a 3-D finite difference modeling are used to study elastic wave propagation and scattering in heterogeneous fraetmed reservoirs. We use two models having different background medium properties and different azimuthal AVO responses and build heteroge...

Shale reservoir heterogeneity is strong, which seriously affects shale gas evaluation and reserves estimation. The Longmaxi Formation of the Luzhou block in southern Sichuan was taken as an example to characterize pore distribution over full scale using micro-computed tomography (CT), focusing on ion beam scanning electron microscopy (FIB-SEM) small-angle neutron scattering (SANS); further, exp...

BACKGROUND Anaplasma phagocytophilum is a Gram-negative bacterium that replicates obligate intracellularly in neutrophils. It is transmitted by Ixodes spp. ticks and causes acute febrile disease in humans, dogs, horses, cats, and livestock. Because A. phagocytophilum is not transmitted transovarially in Ixodes spp., it is thought to depend on reservoir hosts to complete its life cycle. In Europ...
