  rdf:value "The creation of fractures within a reservoir that contains oil or natural gas to increase flow and maximize production. A hydraulic fracture is formed when a fluid is pumped down the well at pressures that exceed the rock strength, causing open fractures to form in the rock."@en, "Generación de fracturas dentro de un depósito de petróleo o gas natural, dirigida a aumentar el flujo y maximizar la producción. Una fractura hidráulica se forma cuando un fluido se bombea al pozo, con presiones que sobrepasan la resistencia de la roca y que producen fracturas en ella."@es ;
