Examining the effect of cemented natural fractures on hydraulic fracture propagation in hydrostone block experiments [PDF]

, 2012
textMicro seismic data and coring studies suggest that hydraulic fractures interact heavily with natural fractures creating complex fracture networks in naturally fractured reservoirs such as the Barnett shale, the Eagle Ford shale, and the Marcellus ...

Naturally Fractured Eocene Flints [PDF]

Nature, 1920
AT a meeting of the Geological Society of London, held on May 5, Mr. S. Hazzledine Warren read a paper entitled “A Natural Eolith Factory beneath the Thanet Sand.” The discovery of flints fractured by natural pressure at the base of the Eocene is not, however, a novel experience, as, in 1910, M. l'Abbe H. Breuil described (“Sur la presence d'Eolithes a

Conservative management versus open reduction and internal fixation for mid-shaft clavicle fractures in adults - The Clavicle Trial: Study protocol for a multicentre randomized controlled trial [PDF]

, 2011
Background: Clavicle fractures account for around 4% of all fractures and up to 44% of fractures of the shoulder girdle. Fractures of the middle third (or mid-shaft) account for approximately 80% of all clavicle fractures.
