this paper proposes a two-step approach for characterizing the reservoir properties of the world’s largest non-associated gas reservoir. this approach integrates geological and petrophysical data and compares them with the field performance analysis to achieve a practical electrofacies clustering. porosity and permeability prediction is done on the basis of linear functions, succeeding the elec...

Adaptation neighborhoods of self-organizing maps for image restoration are presented in this study. Generally, self-organizing maps have been studied for the ordering process and the convergence phase of weight vectors. As a new approach of self-organizing maps, some methods of adaptation neighborhoods for image restoration are proposed. The present algorithm creates a map containing one unit f...

This paper deals with automatically learning the spatial distribution of a set of measurements: images, in the examples presented here. The solution to this problem can be viewed as an instance of robot mapping although it can also be used in other contexts. We examine the problem of organizing an ensemble of images of an environment in terms of the positions from which the images were obtained...
