Integrating Reservoir Characterization: 3D Dynamic, Petrophysical and Geological Description of Reservoir Facies

SPE Asia Pacific Oil and Gas Conference and Exhibition, 2010
Abstract Integrating conventional geologic, petrophysical and reservoir engineering rock typing methods requires studies which incorporate 3D imaging of rock material, 2D petrographic studies, fluid:fluid and fluid:solid interactions (e.g., wettability), and geological facies descriptions.

Seismic Facies-controlled Prestack Simultaneous Inversion of Reservoir Elastic and Petrophysical Parameters

Proceedings, 2018
To improve the accuracy and practicability of elastic and petrophysical parameter inversion, we develop a strategy for estimating the elastic and petrophysical parameters based on the Gassmann equation using deterministic prestack inversion.

Facies and petrophysical modeling of the Upper Bahariya Member in Abu Gharadig oil and gas field, north Western Desert, Egypt

Journal of African Earth Sciences, 2019
The Upper Bahariya Member represents an argillaceous sandstone reservoir and it is one the Late Cretaceous units. There is a need for understanding the detailed facies and petrophysics of this member and identifying whether its petrophysical parameters ...

Electrofacies and Geological Facies for Petrophysical Rock Typing: Khuff C

SPE Saudi Arabia Section Technical Symposium, 2009
Abstract For integrated reservoir characterization a translation scheme must be established to link subsurface data across the disciplines, from the seismic and geological through the petrophysical to the reservoir dynamic properties. This translation process requires data sets that cross discipline boundaries and that establish robust ...

2D joint inversion of geophysical data using petrophysical clustering and facies deformation

GEOPHYSICS, 2015
Geologic expertise and petrophysical relationships can be brought together to provide prior information while inverting multiple geophysical data sets. The merging of such information can result in more realistic solution in the distribution of the model parameters.

Facies uncertainty in petrophysical forward function: A West Africa offshore field example

SEG Technical Program Expanded Abstracts 2011, 2011
In the context of geophysical inversion, a petrophysical forward function provides the link between properties that are directly geophysically detectable (e.g., seismic velocities and attenuation) and rock and fluid properties. Due to heterogeneity of rock properties uncertainty of the petrophysical forward function can be high.

Integrating facies analysis and geostatistical methods in an onshore oil field using petrophysical groups

Interpretation, 2023
Reservoir facies studies are of great importance in different stages of exploration and development of hydrocarbon fields. We have aimed to generate a reservoir facies model for the Asmari Formation in an onshore oil field located in southwest Iran. Input data for electrofacies (EF) clustering algorithms are used, which include gamma-ray (GR), density

Joint estimation of facies boundaries and petrophysical properties in multi-facies channelized reservoirs through ensemble-based Kalman filter and level set parametrization

Journal of Petroleum Science and Engineering, 2018
Ensemble-based assimilation methods are the most promising tools for dynamic characterization of reservoir models. However, because of inherent assumption of Gaussianity, these methods are not directly applicable to channelized reservoirs wherein the ...

Joint Seismic and Petrophysical Inversion Constrained by Facies in a Bayesian Framework

Proceedings, 2017
Summary We present a methodology for simultaneous seismic inversion and reservoir characterization, and apply it to a Norwegian Sea gas field of Jurassic age. Our Bayesian approach allows for joint probabilistic assessment of lithology/fluids, reservoir properties (porosity and saturation) and elastic attributes (acoustic impedance and Vp/Vs), and is ...

Facies, petrophysical and geochemical properties of gravity-flow deposits in reservoir analogs from the Itararé Group (late Carboniferous), Paraná Basin, Brazil

, 2019
Since many reservoirs do not allow direct observation due to their depth and/or difficulty of sampling, studies of analogs have been commonly used as a tool to understand the spatial distribution of reservoir properties.
