Definition - What does Induced Fracture mean?
An Induced Fracture is a crack that is created in the rock bed by the use of any equipment such as drilling machines, drill bits or any other technological means such as hydraulic fracturing. Most often, induced fracturing is applied in the rock formations whose grains are tightly packed and are not permeable. Hydraulic fracturing is used to induce the fractures in the formation so as to enhance oil or gas production.
Petropedia explains Induced Fracture
Induced fracturing is performed with the help of hydraulic fracturing technique in shale formations where the hydrocarbons are tightly packed between the non-permeable rocks under great pressure and are not able to rise to the surface due to lack of space. In this technique, a specially blended liquid with sand grains, aluminum pellets, glass beads, etc., is carried in suspension and pumped down the formation under high pressure. The fracture is induced into the rock bed creating an open crack. When the pressure is released at the surface, the fractures partially close on the materials allowing channels for oil to flow through them into the well.
