An SRV with improved petrophysical properties of the original natural microfracture network, represented by anisotropic and heterogeneous fractal distributions around each of the hydraulic fractures, is considered, and a consistent matrix shape factor distribution is proposed...

...), Photoelectric factor (PE), Bulk Density (RHOB), Neutron Porosity (NPHI) and Compressional Monopole Sonic (DT)), as well as 2d correlations (fence diagrams). To better represent the petrophysical properties, we used a relatively fine grid that covered the area previously described with a total of 242176 cells...

... Abstract Modeling accurate lithofacies and petrophysical properties is a crucial step in the reservoir characterization to capture the geological uncertainty. In addition, the accurate modeling controls reservoir heterogeneity, fluid flow modeling, and history matching, especially in complex...

..., estimated from the more fundamental building blocks of a rock mass, that go beyond the elastic domain. These include the petrophysical properties from which components of the rock mass such as its pore space, frame and solid phase can be assembled from its constituent parts. In this study, we estimate...

... is the relationship between chemofacies and petrophysical characteristics. Petrophysical properties in the Niobrara and Turner vary at the field scale, adding complexity to development planning. Additionally, direct measurement of petrophysical properties to calibrate vintage wireline logs prior to development...

... area, the seismic data, which is a good source of lateral geological information away from well control, can be utilized by the inversion process and subsequent geostatistical analytics to generate high-quality geo-models of facies and petrophysical properties. These products can be used by the asset...

... developed petrophysical property models calibrated to core data for specific facies within a stratigraphic and geographic context. In this study, we integrate data from the petrophysical analysis of log data from over 400 wells and core data from over 50 wells to develop petrophysical property modeling...

... are significantly influenced by dynamic petrophysical properties, which are affected by wettability. We have recently documented a significant impact of geochemistry on wettability of organic-rich mudrocks, which can potentially affect multi-phase fluid flow and water production in these reservoirs. Therefore...

Two semi-analytical modeling approaches are developed for describing the stress-dependency of the petrophysical properties of porous rock formations. The first approach implements a kinetic model and the second approach applies an elastic cylindrical pore...

However, it is unclear what the consequences of CO 2 injection may be – specifically with respect to clay and organic swelling and fracturing in the rock matrix. Characterizing shale petrophysical properties provides important data...

... Abstract Modeling of the petrophysical properties in tight carbonate reservoirs is important for better characterization of reservoir quality. This study aims to investigate the relationship between reservoir properties (porosity and permeability) and ultrasonic P-wave velocity of carbonate...

... Abstract The Barnett and Eagle Ford shale formations are two of the most actively drilled shale plays in the U.S. The petrophysical properties of these organic-rich shales are essential to assess their potential to be developed economically. In this paper, we present a systematic laboratory...

... Summary Lack of firm knowledge about major petrophysical properties of organic rich shales, despite their recent importance in production from self-resourcing accumulations has been a great challenge to our industry. There is no universal definition for the term " Shale" as it is used today...
