UNCONVENTIONAL EXPLORATION FOR NATURAL FRACTURES
Proceedings of SPE Unconventional Gas Recovery Symposium, 1980Abstract 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, 1982This 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), 1987The 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, 19801. 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

An Experiment in Natural Fracture
Lithic Technology, 1986AbstractCobbles and angular chunks of obsidian were subjected to breakage by being sent through the mail. The resulting assemblages of “flakes” and “cores” were analyzed to evaluate various criteria for distinguishing natural fracture from intentional stone knapping.

Mechanism for Network Fracturing in Natural Fractured Reservoir
Advanced Materials Research, 2013By 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, 2005Abstract 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 ...

Natural Fracture Prediction for Discrete Fracture Modelling
Proceedings, 2014There are many uncertainties in the modelling of discrete fracture networks; largely due to their intense spatial variation and a lack of direct integration between interpreted fracture data at the well level and seismic scale fault interpretations. The method described addresses these two major challenges and demonstrates how these inputs can be used ...

Fracture Design Considerations in Naturally Fractured Reservoirs
International Meeting on Petroleum Engineering, 1988ABSTRACT The ability to effectively enhance production through hydraulic fracturing is dependent on an accurate description of the reservoir production mechanism(s). Fracture designs may differ greatly depending on the production mechanism(s). The complex nature of hydraulically fractured reservoirs in which the predominant production
