“…The core test results displayed that the quartz content in the low gamma layers has not increased significantly. The uncertainty of the lithologic profile obtained only by using conventional logging projects is too strong to calculate the carbonate content of the accurate formation [48]. Elemental capture spectroscopy logging provides intuitive mineral types and contents, so it can be directly applied to evaluate formation lithology.…”

In this paper, the development history of geophysical logging technology was reviewed, the application status of logging technology in the geological exploration of hydrology, marine oil and gas, and marine natural gas hydrate was introduced, logging response characteristics and identification methods in various geological exploration projects were summarized, and the current situation and development trend of new logging technology was discussed. With the gradual deepening of complex and unconventional oilgas exploration and development, there are an increasing number of highly deviated wells, horizontal wells, and vertical wells with complex well conditions, promoting the development of unconventional reservoir logging technology as the main logging technology at present. It is urgent to deeply explore basic logging theories, formation testing, downhole fluid analysis, petrophysical analysis and logging response experiments, accelerate the research and development of new logging technologies and equipment, improve the ability and level of logging evaluation for complex reservoirs, and effectively promote the quality and efficiency improvement of unconventional oil-gas exploration.

“…These tools involved a series of records which illustrate the fluid behavior and nature of the reservoir during the production and injection procedures of an oil formation. Figure 2 shows the production logging tools components schematically (Frooqnia et al 2011;Grayson et al 2002;Hoffman and Narr 2012;Li and Zhao 2014;Plastino et al 2017;Sullivan 2007). One of the chief aims of production logging tools is to analyze and investigate the borehole performances like dynamic or static situation of a production well, measure the amount of productivity and injectivity index of zones or layers of a field, monitor the borehole inefficiencies by interpreting obtained logs, diagnose the effectiveness of stimulation or completion processes, and measure the physical condition of a well (Aghli et al 2016;Al-Mulhim et al 2015).…”

Appropriate estimation of permeability is considered as one of the significant concerns of petroleum industries. Due to the growing demand for hydrocarbon fossil fuels in numerous industries, Petroleum Engineers always try to provide holistic and sustainable solutions to measure this parameter more accurately and to calculate the proper original oil in place (OOIP) and initial reserve. Hence, this accuracy estimation helps engineers whether the production and exploration operations are profitable or not and it might virtually eliminate the unnecessary expenditures. The term production logging tools (henceforth; PLT) involve a wide variety of measurement tools and many sensors. It, too, carries interpretation tools which evaluate the formation properties, in respect of the way PLTs would analyze the formation fluid movements inside and outside of the wellbore and subsequently estimate the production flow rate for each layer. On the other hand, it gives production and completion engineers the chance to investigate the appropriate efficiency of production and perforation processes to organize the remediation methodologies or preplan proper designing for modifying completion procedures which have based on the production logging tools interpretation. The purpose of this comprehensive research is to compare two different techniques (PLT and core analysis) of permeability measurement in a six-layered fractured reservoir and subsequently normalize each parameter to obtain the proper estimation. As a result, according to the evaluation of each technique, the amount of permeability in the layers 1, 2, 3, and 5 is relatively close to each other. Furthermore, regarding higher expenses of core analysis tests and the reliability of PLTs according to the results of this paper in the four out of six individual layers, Emeraude software by utilizing PLT interpretation could be a substitution and preferable methodology instead of core analysis measurements.

“…One of the chief aims of production logging tool is to evaluate the fluid flow inside and outside the casing or in some occasions to evaluate the well completion directly. The major application of this tool is to obtain current profile in the wellbore; in respect of the way, the distribution of fluid flow in the wellbore is being measured (Li and Zhao, 2014). The schematic of production tools and its instruments are as shown in Figures 1 and 2.…”

Fractured carbonated reservoir is one type of unconventional reservoirs which has low permeability rather than conventional reservoirs in terms of complex depositional and diagenetic environment. In most of the fractured carbonated reservoirs, fluid flow characteristics such as permeability and porosity are generally difficult to estimate and the most porous intervals are not always the best reservoirs as the intervals of equivalent porosity. Permeability plays the substantial role in moving the fluid flow from the fractures of the reservoir to the wellbore. Due to the fact that, calculating the appropriate amount of permeability was seriously doubted and there were numerous challenges for petroleum engineers to obtain the accurate quantity. Estimation of permeability using regular methods such as core analysis and well testing methods are outrageously expensive and time consuming. Furthermore, a simple correlation between permeability and porosity cannot be developed. Therefore, the prediction of permeability in heterogeneous carbonates by production logging tools is a preferable methodology to reduce the squander sums of money and time in measuring the fluid properties of a carbonate reservoir such as permeability, measuring the well fluid profile, detection of mechanical problems and evaluation of well completion procedures. That is to say that, production logging tools is performed as a powerful and applicable instrument to estimate the flow rate, water-oil contact, and other fluid properties.
