A Grey System Approach for Estimating the Hölderian Regularity with an Application to Algerian Well Log Data
Autor: Said Gaci, Orietta Nicolis
Publikováno v: Fractal and Fractional, Vol 5, Iss 3, p 86 (2021)
The Hölderian regularity is an important mathematical feature of a signal, connected with the physical nature of the measured parameter. Many algorithms have been proposed in literature for estimating the local Hölder exponent value, but all of the

Local regularity investigation of well logs from an Algerian tight reservoir
Autor: Orietta Nicolis, Said Gaci
Geophysical well logs often exhibit a complex behavior that can be described by fractal stochastic models. Since fractional Brownian motions, which are monofractals presenting a constant Holderian regularity degree everywhere, they are not appropriat

Review chapter on petroleum exploration section
Autor: Said Gaci
Nowadays, the decrease in the world oil/gas reserves is a major challenge for both energy producers and consumers. Therefore, thorough exploration and production strategies are highly requested to sustain the world energy production level. In this vi

Empirical mode decomposition-based approaches for predicting velocity well logs in a petroleum reservoir
Autor: Said Gaci, Mohammed Farfour
P- and S-wave velocity (Vp & Vs) are of a high interest in petroleum exploration. Understanding the relationship between them brings key information for petrophysics, inversion, and formation evaluation. In contrast with Vp log data, Vs logs are not
