Catala, G. The classical practice in quantitative production log interpretation involves the use of the tandem flow and density measurements. The usual companion logs such as temperature and pressure are traditionally only exploited qualitatively and for the determination of insitu fluid properties.

Chandran, T. Production logging in horizontal wells is always challenging compared to vertical wells. These challenges include the physical deployment of the tools, presence of restrictions along the horizontal section that complicates the analysis, the huge volume of data from different tools and modes that should be interpreted, and later to make meaningful interpretation from these analyzed data.

The presence of the three phase fluid flow will further complicate production analysis. On the other hand, changes in the flow pattern laterally over the horizontal section result in uneven increase or decrease in the fluid rates.

Other fluids slow down their flow rates in relation to different parameters and hole condition. In order to fully analyze the huge data acquired using different tools, a thorough investigation on the flow patterns and fluid regime is required to quality check the data before processing and interpreting.

Once processed, different log data should be separately analyzed and later compared with other available data. Combined analysis show different flow profile over the horizontal section, along with possible geological features. In this presentation case history from the region is presented and thoroughly discussed. Some intervals are more specifically analyzed and compared to other logs run in order to confirm the outcomes. The analyzed production log data improved the ability of better optimizing well production rates and managing their integrities within the reservoir.

The use of the combination of different Production Logging Tool PLT modes in vertical wells was always practical in finding the flow profile for different phases. Though, the use of the same set of modes has faced a serious challenge in horizontal wells. In horizontal wells, the fluid density, temperature, hold up, pressure and spinner modes have all failed to provide the actual flow profile of different fluids. The segregation of different phases was the challenge to these modes.

Production Logging Measurements and Analysis

Production logging encompasses a number of cased hole logging measurements usually run in completed injection or production wells to evaluate the performance of the well itself or of the reservoir. Although the most common application of production logging is to obtain the well flow profile, a measure of the distribution of fluid flow into or out of the wellbore, there are numerous other applications, such as detecting channels or leaks. The chapter is organized according to the logging environment or logging objective. First, the use of temperature, radioactive tracer, and spinner flowmeter logs for measuring flow profiles in single-phase flow is described. Then, the more difficult application of logging in multiphase flow is treated, introducing the basket flowmeter, density, and capacitance logs that are used in this environment. Finally, production logging techniques for completion evaluation are considered.

The measuring instruments have some errors in the measurement of high water cut production wells, and many domestic oil fields are also in high water cut state. The measured data from the conventional production logging instrument are all almost inaccurate. This project has designed a staggered probe array flow meter well logging apparatus based on the characteristic of electromagnetic wave specific retention meter that can fully cover the wellbore fluid and improve flow measurement accuracy. Directional well drilling technology is becoming more and more perfect. Related completion technology is also constantly improved [ 1 ]. The number of horizontal wells is also increasing.

Design and Implementation of the Array Logging Tool on Horizontal Production Logging

Thousands of high-angle and horizontal wells have been drilled in the last ten years. As a result, there are many mature fields with complex well production problems. For decades, production logs have been used in new wells to optimize ultimate recovery and to help avoid potential production problems.
