Amplitude vs. Angle — Influence of petrophysical parameters in porous media

SEG Technical Program Expanded Abstracts 1998, 1998
The availability and use of seismic data in reservoir development is increasing. This paper describes the analysis of reflections, for elastic and porous medium considering variations in the petrophysical parameters of porosity, permeability and viscosity.

Rock-Fabric, Petrophysical Parameters, and Classification

1999
The goal of reservoir characterization is to describe the spatial distribution of petrophysical parameters such as porosity, permeability, and saturation. Wireline logs, core analyses, production data, pressure buildups, and tracer tests provide quantitative measurements of petrophysical parameters in the vicinity of the wellbore.

Investigating the dependence of shear wave velocity on petrophysical parameters

Journal of Petroleum Science and Engineering, 2016
Abstract The dependence of the shear wave velocity ( V s ) of water-saturated reservoir rocks on petrophysical parameters was investigated. Two general regression neural network (GRNN) models were developed to predict V s of sandstones, shaly sands, and carbonate rocks as a function of the compressional velocity ( V p

Simultaneous inversion of petrophysical parameters based on Metropolis sampling algorithm

SEG Technical Program Expanded Abstracts 2014, 2014
Summary Simultaneous inversion of petrophysical parameters based on Metropolis sampling algorithm is formulated in the Bayesian framework, combining statistical petrophysics with the geostatistical priori information. Firstly, we can get the geostatistical priori information through Fast Fourier Transform- Moving Average (FFT-MA) and Gradual ...

Carbonate Petrophysical Parameters Derived from 3D Images (Best of AAPG)

71st EAGE Conference and Exhibition incorporating SPE EUROPEC 2009, 2009
Carbonate rocks are extremely diverse and their pore spaces complex and heterogeneous. Large uncertainties in the petrophysical properties of carbonates are due to wide variations in pore type, pore shape and interconnectivity.

Permeability relation with other petrophysical parameters for periodic porous media

GEOPHYSICS, 1999
We modeled permeability (k) estimation based on porosity (ϕ), electrical formation factor (F), and nuclear magnetic resonance (NMR) relaxation time (T), using periodic structures of touching and overlapping spheres. The formation factors for these systems were calculated using the theory of bounds of bulk effective conductivity for a two‐component ...

Simultaneously Estimate Petrophysical Parameters and Average Mud-filtrate Invasion Rates

71st EAGE Conference and Exhibition incorporating SPE EUROPEC 2009, 2009
A 2.5D inversion approach is introduced for interpreting the induction logging data. The inversion is constrained by using a multiphase fluid-flow model which simulates the mud-filtrate invasion process and calculates the spatial distribution of the ...

Determination of Petrophysical Parameters Using Wireline Logs in Low Salinity Reservoirs

Proceedings of SPE Asia Pacific Oil and Gas Conference, 1995
Abstract This study defines an approach to determine porosity, fluid saturations and permeabilities from wireline log data in sandstone reservoirs containing low salinity formation brines. An extensive set of measurements were made on low invasion core were analyzed to establish the ground truth, and to control the input parameter ...

Petrophysical Parameter Calculation Based on NMR Echo Data in Tight Sandstone

IEEE Transactions on Geoscience and Remote Sensing, 2019
Bound water saturation ( $S_{\mathrm {wb}}$ ) and permeability are the important petrophysical parameters. However, the traditional methods for the calculation of $S_{\mathrm {wb}}$ and permeability based on the nuclear magnetic resonance (NMR) transverse relaxation time ( $T_{2}$ ) distributions are not applicable for tight sandstone ...
