Reactivation mechanism of natural fractures by hydraulic fracturing in naturally fractured shale reservoirs

Journal of Natural Gas Science and Engineering, 2015
Abstract Hydraulic fracturing technique has been commonly used in the development of shale reservoir aiming to produce from complex network of fractures. One of the key parameters that affects the hydraulic fracture complexity is the natural fracture in the shale reservoir.

Geometric nature of hydraulic fracture propagation in naturally-fractured reservoirs

Computers and Geotechnics, 2017
Abstract The geometry of hydraulic fracture propagation in the absence and presence of natural fractures in reservoirs was studied. The results revealed a marked influence of natural fractures on the symmetry of fracture propagation observed for rock free of natural fractures.

Sternal fractures — The natural history

Annals of Emergency Medicine, 1988
A five-year retrospective study was undertaken to analyze the natural history of sternal fractures and to scrutinize the current method of management. Sixty-six patients with documented sternal fractures were evaluated. The most common mechanism of injury was motor vehicle accidents (59%). Most of these victims did not wear seat belts.

Fracture Porosity of Naturally Fractured Reservoirs

Proceedings of First International Oil Conference and Exhibition in Mexico, 2006
Abstract The storage capacity ratio, ω, measures the flow capacitance of the secondary porosity and the interporosity flow parameter, λ, is related to the heterogeneity scale of the system. Currently, both parameters λ and ω are obtained from well test data by using the conventional semilog analysis, type-curve matching or the TDS ...

Hydraulic Fracturing in a Naturally Fractured Reservoir

International Petroleum Conference and Exhibition of Mexico, 1994
Abstract Hydraulic fracturing of wells in naturally fractured reservoirs can differ dramatically from fracturing wells in conventional isotropic reservoirs. Fluid leakoff is the primary difference. In conventional reservoirs, fluid leakoff is controlled by reservoir matrix and fracture fluid parameters.

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.

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.

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.

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.
