FRACTAL ANALYSIS OF DIGIT ROCK CORES

Fractals, 2020
The rock cores of low permeability reservoirs have special pore structures, which are the essential factors to determine the seepage capacity and oil displacement efficiency and directly affect oil and gas reserves and oil well productivity. This paper studies 16 digital rock core samples.

Digital Rock Physics: Using CT Scans to Compute Rock Properties

IEEE Signal Processing Magazine, 2018
Profitable production from oil and gas reservoirs is essential in the petroleum industry, and solutions for many reservoir engineering problems rely on an accurate estimation of rock's physical properties. Traditional property estimation using conventional laboratory measurements has a high turnover time.

A Multiscale Digital Model for Borehole Based on Digital Rock Physics

Proceedings, 2015
Reservoir rocks are heterogeneous at a range of scales. The scale of digital rock physics is mainly at centimeter-level or smaller and can’t effectively study the macroscopic factors. A 3D digital borehole model (DBM) is built referred to geological modeling and integrates logging information, electrical borehole images and CT data of whole core, core ...

Classification of Digital Rocks by Machine Learning

Proceedings, 2012
The availability of high-resolution 3D digital rocks in ever increasing quantities calls for intelligent Machine Learning (ML) techniques to classify them according to diverse characteristics of their pore structures. If stable classes could be identified, they would aid us to develop better models for rock typing, to gain sounder understanding of the ...

Synergies Between Laboratory and Digital Rock For Improvement of Rock Models

SPWLA 65th Annual Symposium Transactions
In recent years, digital rock physics (DRP) has evolved significantly, diversifying its applications in numerical simulations for determining a series of petrophysical properties and automated image analysis using artificial-intelligence-based algorithms, among others, becoming a routine part of reservoir analysis at Petrobras.
