Detection of perforation intervals in oil well completion based on geological, drilling and well logging data

Abstract

Optimum perforation location selection is an important task to improve well production, and hence the reservoir development process. This paper aims to detect the optimum perforation interval by determining the oil zone interval, petrophysical properties, and productivity ratio to check the efficiency of the perforating process. Drilling, geological and Well log data were used to achieve this study. Geological data such as the depth WOC and the contour map are used to make a 2D cross-sectional of the WOC by using petrel 2009 software. It has been used to determine the well location in the structure, whether it was in the crust or the flank of structure. The drilling history data such as mud weigh, mud cake resistivity...etc. are used to make environmental correction for well logs device to obtain corrected borehole readings. The well logs data are inserted into Interactive Petrophysics software to make the environmental corrections, interpretations and determine the oil zone interval.
