... understanding how fracturing a rock sample under a deformation regime affects its permeability, detecting and measuring fracture properties is fundamental. To detect and measure fracture features from microCT images in a repeatable and semi-automatic manner, it is required to produce consistent fracture...

... Summary Usually, conventional azimuthal AVO (AVOZ) inversion method is based on two-term Rüger equation, which might give rise to inaccuracy in estimating fracture properties for large-offset data due to neglecting the third term. Nowadays, the industry is increasingly acquiring large-offset...

... have shown the potential of using frequency dependent seismic attributes to estimate reservoir seismic anisotropy. In this study, the objective of the inversion is to estimate fracture properties including fracture strike, fracture density, fracture length and fluid type from seismic frequency...

... reflectivity with the full orthorhombic model before inverting parameters from this data with the Rüger equation. We demonstrate a number of possible ambiguities in interpretation of the Rüger parameters; in particular the anisotropic gradient can be sensitive to composition as well as fracture properties. We...

... Summary Traditional amplitude variation with offset and azimuth (AVOAZ) analysis for fracture characterization extracts fracture properties through analyzing the characteristics of the reflection amplitude variation with offset and azimuth. Validity of the method relies on its basic...

... is performed to obtain azimuthal velocity models, which can be used to estimate fracture properties and improve imaging. In fracture characterization of the whole survey area, the result estimated from the splitting analysis proves to be a more robust representation of fracture properties. However...

... of a rock and illustrates which P-wave and S- wave Amplitude Variation with Offset (AVO) attributes might be helpful for quantitative interpretation of fracture properties like fracture-orientation, fracture-density and fracture-fill. A statistical rock physics model is constructed for Ordovician age...

... the seismic image and to estimate the fracture properties from these anomalies, we study fracture-induced azimuthal anisotropy on WAZ-ADCIG and propose an efficient method for analysing the WAZ-ADCIGs. The idea of this method is to correct the fracture-induced azimuthal variation on WAZ-ADCIG by applying...

... from flow simulation. Introduction The design of horizontal wells and hydraulic fracture stimulation in unconventional reservoir requires a detailed understanding of the variations in matrix and fracture properties. Matrix properties control not only the volume of hydrocarbons and the ability...

... fractured nature can be used to enhance production of the reservoir. The fracture properties of interest in this study (to be inferred) are fracture orientation and excess compliance, where each of these properties are assumed to vary spatially over a 2D lateral grid which is assumed to represent the top...

.... Recently, we proposed a variant of the LSI model considering the heterogeneity in the in-plane fracture properties. This modified model considers wave-induced, fracture-parallel fluid flow induced by passing seismic waves. The research discussed in this paper applies this new LSI model to heterogeneous...

.... In the second method, the region probed by the seismic beam varied from 15 mm to 30 mm to 60 mm to determine the effect of scale in interpreting the changes in fracture properties. To vary the size of the region probed, a set of acoustic lens was developed to collimate the seismic wavefront over different...
