On the Stability of Pressure and Velocity Computations for Heterogeneous Reservoirs
نویسندگان
چکیده
This paper is concerned with the stability of self-adjoint second order elliptic problems with respect to perturbations of the involved coeecient functions. In particular, we study such behaviour for the pressure equation related to incompressible or steady state ow in a heterogeneous reservoir. We establish analytical estimates on the changes in the pressure and velocity caused by mobility perturbations measured by the L 1 norm. This stability analysis is complemented by numerical experiments.

Studying the Effect of Horizontal Drains on Stability of Heterogeneous and Homogeneous Earth Dams during Rapid Drawdown Condition
One of the main concerns to design earth dam is the stability of the upstream slope of the earth dam in phase of rapid drawdown. Confined pore water pressure reduces the effective stress in this mode, so possibility of the instability and slippage will be increased. The main goal of this research is to investigate changes in the pore water pressure by using horizontal drains in upstream slope o...
متن کاملFluid Properties Effects on Sand Production using Discrete Element Method
Oil production may be accompanied by Sand Production (SP) in the weak sandstone reservoirs. Fluid flow is an important factor in transporting the separated grains and completing the SP mechanism. In this paper, the effect of fluid parameters, fluid flow, and fluid pressure on the SP is investigated by applying the Discrete Element Method (DEM). Parametric studies show that fluid velocity is red...

متن کاملTest-retest reliability and minimal detectable change for center of pressure measures of postural stability in elderly subjects
Abstract Background: Postural instability has been identified as a potential precursor of falls in elderly subjects. Postural stability in quiet stance is commonly assessed with center of pressure (COP) measures. The purpose of this study was to determine testretest reliability and minimal detectable change (MDC) for the center of pressure (COP) measures in the elderly subjects. Met...
متن کاملMATHEMATICAL ANALYSIS OF NEWLY DESIGNED TWO POROUS LAYERS SLIDER BEARING WITH A CONVEX PAD UPPER SURFACE CONSIDERING SLIP AND SQUEEZE VELOCITY USING FERROFLUID LUBRICANT
This paper proposes mathematical modeling and analysis of ferrofluid lubricated newly designed slider bearing having convex pad (surface or plate) stator with two porous layers attached to the slider. The problem considers the effect of slip velocity proposed by Sparrow et. al.[1] and modified by Shah et. al.[2] at the film-porous interface. The squeeze velocity V=−which appears when the upper ...
