چکیده

We developed a simple method to parameterise fluvial point bars, which are common sedimentary deposits in meandering river environments. The method needs four points defining the point bar and is based on high-resolution seismic data. A model geometry is compared with the real point bar geometry. We optimise the model parameters by minimizing the error in the area covered by both objects. The method was applied to real seismic data from an oil reservoir in South America.

Analyzing the Illumination and Resolution in Seismic Survey Designing

Seismic modeling aids the geophysicists to have a better understanding of the subsurface image before the seismic acquisition, processing, and interpretation. In this regard, seismic survey modeling is employed to make a model close to the real structure and to obtain very realistic synthetic seismic data. The objective of this study is to analyze the resolution and illumination of the fault by...

Constrained Seismic Sequence Stratigraphy of Asmari - Kajhdumi interval with well-log Data

Sequence stratigraphy is a key step in interpretation of the seismic reflection data. It was originally developed by seismic specialists, and then the usage of high-resolution well logs and core data was taken into consideration in its implementation. The current paper aims in performing sequence stratigraphy using three-dimensional seismic data, well logs (gamma ray, sonic, porosity, density, ...

Synchrosqueezing-based Transform and its Application in Seismic Data Analysis

Seismic waves are non-stationary due to its propagation through the earth. Time-frequency transforms are suitable tools for analyzing non-stationary seismic signals. Spectral decomposition can reveal the non-stationary characteristics which cannot be easily observed in the time or frequency representation alone. Various types of spectral decomposition methods have been introduced by some resear...
