Abstract:
Wellbore storage effect is one of the biggest problems of petroleum engineers in analyzing the reservoir properties. In this phenomenon, at the beginning time of production from a reservoir, the fluid is initially produced from the well and not from the reservoir. Due to this effect, the pressures are distorted and could not be used in reservoir analysis. In this thesis the wellbore storage effect would be removed in naturally fractured reservoirs using deconvolution method. Using this method the range of data used could be increased. In this method special techniques are used in order to determine reservoir behaviour.
Using the method presented in this thesis, petroleum engineers could analyze the reservoir and determine its properties properly without any wellbore storage distortion at the beginning times. Less time for reservoir analysis, less cost and highest accuracy are the least advantages of using this method. In other words the aim of this thesis is to provide the data part which is distorted by the wellbore storage effect in order to better interpretation of the reservoir.
