Petrophysical Seismic Inversion
SEG Technical Program Expanded Abstracts 2005, 2005As part of a two years collaborative RD the geomodels are not simply conditioned to seismic attributes by seismic-guided mapping but reproduce prestack seismic measurements (Bornard et al., 2005). A key component of the inversion methodology is a Petro-Elastic Model (PEM) that links the reservoir properties stored in the geomodel (e.g., porosity, rock ...

Seismic modeling and inversion
Proceedings of the IEEE, 1984The seismic method of petroleum exploration has always been an inverse technique. The explorationist has used data from seismic and other sources to derive an indirect description of a potential reservoir. Key to his success has been the use of forward-modeling methods to aid him in relating what he sees in the seismic data to what he expects to see ...

EAGE/SEG Research Workshop 1990, 1990
In most seismic applications, the traveltimes of the primary reflections constitute the main information about the subsurface. The traveltimes may be picked and used directly. or the parameters in a traveltime approximation may be estimated from the seismic data.

Multidimensional Seismic Inversion
2001Our goal is present a theory for determining the characteristics of the interior of a body bases only on observations made on some boundary surface. In particular, we are interested in finding ways of imaging structures inside a body. In addition to imaging, we hae the more ambitious goal of actually determining values of certain material parameters ...

Evaluation of Seismic Trace Inversion Techniques
Exploration Geophysics, 1993The performance of three post-stack seismic inversion techniques has been evaluated using synthetic and VSP data. The application of classical recursive inversion to simple synthetic models demonstrates the importance of low frequencies in trace inversion.

Summary: Two well-known iterative algorithms, steepest descent and conjugate- gradient descent, are used to solve the nonlinear seismic inversion problem from reflection data by minimizing the mean-square error between the measured data and data generated by the estimated model.

Seismic velocity inversion with genetic algorithms
Proceedings of the 1999 Congress on Evolutionary Computation-CEC99 (Cat. No. 99TH8406), 2003We use genetic algorithms to find geologically plausible sub-surface models from seismic travel-time data. Given a sub-surface model, the physics of wave propagation through refractive media can be used to compute travel times for seismic waves. However, in practice, we have to solve the inverse problem: travel-times are available and the problem is to

Seismic Modelling and Inversion
2016Modeling is a computational process to determine the seismic response of a given geologic model and can be 1D, 2D and 3D and structural or stratigraphic. Synthetic seismogram is the most elementary and common example of one-dimensional (1D) modelled seismic response of the earth.

Proceedings, 1995
A method is presented to model post-stack seismic data by simple stratigraphic interpolation of the 'seismic character'. The seismic character is derived from the seismic data at the well positions. Interpolation is done using interpreted time horizons and a stratigraphic framework that describes the relations between the horizons and the interpolation

Future progress in science and technology will primarily come from multidisciplinary research. This does not mean that disciplinary science can be neglected. On the contrary, multidisciplinary research can only be of high quality if excellent disciplinary scientists are involved. However, it does mean that today’s “loose pieces of specialized knowledge”
