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.

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

72nd EAGE Conference and Exhibition incorporating SPE EUROPEC 2010, 2010
Numerical results have shown that at high angle of approach and differential stress, it is more likely for the hydraulic fracture to cross the natural fracture, whereas for a case where angle of approach and differential stress are low the hydraulic fracture is more likely to be arrested and then reorient the existing path and propagate through natural

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 ...

Effect of a natural fracture on hydraulic fracture propagation
2004The effect of an existing fracture in a naturally fractured formation on the extension of a hydraulically induced natural fracture has been studied. Fracture interaction criterion was presented and a numerical model was developed to predict the dynamic fracture dimensions based on PKN³¹ fracture mechanics.
