Exploratory Factor Analysis of Wireline Logs Using a Float-Encoded Genetic Algorithm
In the paper, a novel inversion approach is used for the solution of the problem of factor analysis. The float-encoded genetic algorithm as a global...

Reduced-Order Modeling of Subsurface Multi-phase Flow Models Using Deep Residual Recurrent Neural Networks
We present a reduced-order modeling technique for subsurface multi-phase flow problems building on the recently introduced deep residual recurrent...

A new rock creep model based on variable-order fractional derivatives and continuum damage mechanics
The creep model is the main form of rock model used to describe the rheological behavior of rocks. A large number of creep models have been proposed,...

Fuzzy Logic
Fuzzy logic is an extension to Boolean logic and was developed by Zadeh in 1965. While classical logic only allows values of 1 for ‘true’ and ‘0’ for...

Extraction and prediction of indices for monsoon intraseasonal oscillations: an approach based on nonlinear Laplacian spectral analysis
An improved index for real-time monitoring and forecast verification of monsoon intraseasonal oscillations (MISOs) is introduced using the recently...

An Efficient Algorithm Scheme for Implementing the TEMOM for Resolving Aerosol Dynamics
This paper presents a new algorithm scheme for implementing the Taylor-series expansion method of moments (TEMOM), which is a general method for...

Where “Small Is Beautiful”—Mathematical Modelling and Free Surface Flows
Mathematical and computational models in river and canal hydraulics often require data that may not be available, or it might be available and...

Modeling Multiphase Mass Transport
In this chapter, we construct mass transport models for the case of multiple (i.e., two or three immiscible) fluid phases that occupy the void space...

Automatic well-testing model diagnosis and parameter estimation using artificial neural networks and design of experiments
The well-testing analysis is performed in two consecutive steps including identification of underlying reservoir models and estimation of...

Identifying Space-Dependent Coefficients and the Order of Fractionality in Fractional Advection–Diffusion Equation
Tracer tests in natural porous media sometimes show abnormalities that suggest considering a fractional variant of the advection–diffusion equation...

Halogens in Silicic Magmas and Their Hydrothermal Systems
Halogens, mainly F and Cl, play key roles in the evolution and rheology of silicic magmas, magmatic-hydrothermal transition, partitioning of metals...

Storage of CO2 in depleted/producing oil reservoirs
This chapter presents a framework for an environmental based assessment of CO2 storage operations in depleted/producing oil reservoirs. We specially...

D
Introduced by the American geologist, Chester Robert Pelto (1915–1984) (Pelto 1954), the D function expresses the relationship between the relative...

New model of groundwater flowing within a confine aquifer: application of Caputo-Fabrizio derivative
A novel definition of the concept of derivative with fractional order was introduced. To further enhance the mathematical model describing the flow...
