The Nature of Fracture

2016
Our objective in this introductory chapter will be to describe the general features of the fracture process and to introduce some of the terminology that will be used. After doing this, we will attempt to trace the route by which our present understanding of fracture developed.

Measuring Hydraulic Fracture Growth in Naturally Fractured Rock

SPE Annual Technical Conference and Exhibition, 2009
Abstract A field experiment was carried out to measure hydraulic fracture growth in naturally fractured rock. Hydraulic fracture interactions with pre-existing natural fractures, shear zones, veins, and adjacent hydraulic fractures were measured and mapped during the project.

Are natural fractures pervasive?

2021
Fractures and their connectivity are essential for fluid flow in low perme-ability formations. Abundant outcrops can only provide two-dimensional (2D) information, but subsurface fractures are three-dimensional (3D). The percola-tion status of 3D fracture networks and their 2D cross-section maps are rarely investigated simultaneously.

UNCONVENTIONAL EXPLORATION FOR NATURAL FRACTURES

Proceedings of SPE Unconventional Gas Recovery Symposium, 1980
Abstract This is a progress report on the evaluation of a new unconventional exploration technique for locating the natural fracture reservoirs in the Devonian - Ohio Shale. Five PHASE I tests have been drilled, cored, logged, cased and are currently being tested.

On the statistical nature of fracture

International Journal of Fracture, 1982
This paper explores the statistical nature of the mechanisms of fracture in structural materials and the loads that initiate them. The result of employing either a weak link or bundle model in the application of statistics to problems of fracture is examined.

The Fractal Nature of Fracture

Europhysics Letters (EPL), 1987
The fractal geometry of fracture patterns in materials is explored by means of a simple model which incorporates the equations of elasticity and simple rules for fracture propagation. Different isotropic media and boundary conditions are considered. Self-similar patterns with fractal dimensions nearly independent of the elastic constants are obtained.

Nature of fractures in pyrocerams

Strength of Materials, 1980
1. The completely rough fracture surface of pyroceram 4 indicates that the surface and the bulk of this material have equal strength. This is confirmed by the equal defectiveness of the surface and of the fracture of pyroceram 4. 2. The fracture surface of pyrocerams 1–3 has several zones differing in roughness and defectiveness; this is

Mechanism for Network Fracturing in Natural Fractured Reservoir

Advanced Materials Research, 2013
By the methods of in-house experiment and theory analysis, the fracture initiation, stretch and interconnected mechanism of natural fracture is studied in the fracturing process of main fracture and branch fracture extending. The results have shown that, the hydraulic fracture in fractured formation is composed of a few main fractures in large size and

Effect of Natural Fractures on Hydraulic Fracture Propagation

SPE European Formation Damage Conference, 2005
Abstract Various fracture interaction criteria were reviewed and a systematic study is presented to analyze the effect of natural fractures on hydraulic fracture propagation. From the literature review, the approach of Warpinski and Teufel was adopted to evaluat the fracture propagation that would occur after a hydraulic fracture ...

Naturally Fractured Reservoirs

2019
Currently, there are numerous of authors defined the fracture from a different perspective, However, from the geo-mechanical viewpoint; a fracture is defined as a surface in which a loss of solidity has taken place.
