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

Rock fracture kinetics of the facture mesh system in shale gas reservoirs

Petroleum Exploration and Development, 2012
The formation mechanism of fracture mesh and the mechanism of activating natural closed fractures during shale fracturing are studied based on rock fracture kinetics. It is found that steering conditions should be satisfied at both left and right ends of
