oil production optimization is one of the main targets of reservoir management. smart well technology gives the ability of real time oil production optimization. although this technology has many advantages; optimum adjustment or sizing of corresponding valves is still an issue to be solved. in this research, optimum port sizing of inflow control devices (icds) which are passive control valves ...

Inflow control devices (ICD), which prevent water breakthrough by controlling the inflow profile of a well, have been used successfully in many oilfields. This paper will introduce a new discovery and an unsuccessful example. Moreover, this paper investigates meticulously and thoroughly to find the application conditions of the new discovery. Based on permeability rush coefficient and permeabil...

Acoustic data measured in a fan test facility with and without an inflow control device (ICD) over the inlet were analyzed using cyclostationary analysis technique, which separates total power into rotor-locked fluctuating component. Measurements taken mode detection ring upstream of rotor far-field microphones for configurations subsonic supersonic blade tip speeds. The ICD reduces component s...

Steam assisted gravity drainage is a thermal method for enhanced bitumen recovery. In this method, steam injected to and heavy oil reduce the viscosity make mobile. However, early breakthrough of in some parts well results loss required amount contact with cold bitumen, poor distribution chamber. This limits production increases SAGD operation cost. Autonomous inflow control valve (AICV) able p...

BACKGROUND Multiple clinical trials have shown that a properly functioning implantable cardioverter-defibrillator (ICD) is capable of interrupting sudden death caused by ventricular tachyarrhythmias. However, ICDs are complex medical devices, and they do not always perform as expected or they may fail completely. Exposure of ICD recipients to professional or media reports that their specific de...

The rate of inflow to a long well can vary along its completion length, e.g. due to frictional pressure losses or reservoir heterogeneity. These variations often negatively affect the oil sweep efficiency and the ultimate oil recovery. Inflow Control Devices (ICDs) represent a mature well completion technology which provides uniformity of the inflow profile by restricting high specific inflow s...

After years of research and practice, ICD well completion technology has become a relatively mature technology, been successfully applied in hundreds horizontal Wells abroad. However, due to many factors affecting effect, evaluation methods have not completely established. At present, the main index water control development effect is balance inflow profile inhibit production, involve reservoir...
