A case study testing the effectiveness of neural networks for permeability determination in heterogeneous media using basic rock properties is presented. The dataset used consists 213 core samples from Morrow and Viola formations Kansas, United States. characterizing parameters cores are porosity (ϕ), water oil saturations (Sw So), grain density (GD), additional variables well logs induction re...

BACKGROUND Long-term human exposure to ambient pollutants can be an important contributing or etiologic factor of many chronic diseases. Spatiotemporal estimation (mapping) of long-term exposure at residential areas based on field observations recorded in the U.S. Environmental Protection Agency's Air Quality System often suffer from missing data issues due to the scarce monitoring network acro...

In medical imaging there is a frequent need to magnify a certain region of interest (ROI) of an image. However many modalities suffer from severe noise and traditional upscaling methods produce poor enlargement results. We present an approach based on cross-scale similarity of an image extendable to sequences using time domain information without explicit motion compensation. It combines noise ...

Carbonate reservoirs are a highly heterogeneous type of reservoir characterized by the presence large amount vugs and pores. During two-phase displacement, flow regime in might be gravity segregated. The distribution pattern fluid would accelerate water downward horizontal directions, meanwhile decelerating an upward direction, resulting different oil recovery ratio. This gives rise to question...

Despite their dizzying speed, modern supercomputers are still incapable of handling many most vital scientific problems. This is primarily due to the scale gap, which exists between the microscopic scale at which physical laws are given and the much larger scale of phenomena we wish to understand. This gap implies, first of all, a huge number of variables (e.g., atoms or gridpoints or pixels), ...

Natural depositional processes frequently give rise to the heterogeneous multi-layer system, which is often overlooked but essential for simulation of a geological process. The sediments undergo large-strain process in shallow depth and small-strain deep depth. With transform matrix Laplace transformation, new method solving multilayer (Terzaghi) (Gibson) consolidations proposed. Results from t...
