Abstract

Abstract: Production logging tools (PLTs) are one type of cased hole logging, run during the production or injection stages of a well’s life, for obtaining fluid types and measuring fluid rates in the borehole for each perforation interval, and to better understand the well productivity or the well injectivity of the interest zones, also, to detect some well problems, such as cross-flow, tubing leak, casing leak. In this study, we interpreted production logging tools by Emeraude software from Kappa company to knowing which perforation interval represents the most contributing to the hydrocarbon production and to detect if there is a cross-flow problem or not, for well (X): vertical oil-producing well that belongs to (Y) oilfield, perforated with six perforation intervals, and the results were: the first two perforation intervals represent the less production interval, which accounts for 2.89 and 3.57% of the total downhole rate, and the water cut is about 27 and 32% on the surface respectively. Perforation intervals 3 and 4 do not contribute to the production. Perforation interval 5 represents the main production interval which accounts for 65.68 % of the total downhole rate, and this interval is the main water production interval with water cut about 36% on the surface, and the perforation interval 6 represents the secondary production interval which accounts for 27.86% of the total downhole rate, and the water cut is about 5% on the surface. In addition, there is no cross-flow problem, however, PLTs must be lowered in shut-in conditions to confirm this.
