This paper addresses problems of reservoir fluid migrations in the process CO2 sequestration a partially depleted petroleum reservoir. A detailed analysis is required to obtain fundamental characteristics structure, including estimation its capacity and leakage risks. The presents general discussion relevant mechanisms their contributions analysed issues. proposed approach solve relies on usage...

Attenuation results in loss of seismic wave intensity over distance and time. Attenuation via viscous dissipation results from relative fluid-solid motion and pressure gradients within the fluid, which is contained in a pore or crack. Here, a classic derivation of dissipative attenuation is summarized and its drawbacks and need for derivations specific to the microscopic scale are explained. Tw...

Reduced cerebrospinal fluid amyloid-b42 and increased retention of florbetapir positron emission tomography are biomarkers reflecting cortical amyloid load in Alzheimer’s disease. However, these measurements do not always agree and may represent partly different aspects of the underlying Alzheimer’s disease pathology. The goal of this study was therefore to test if cerebrospinal fluid and posit...
