Brittleness Index: From Conventional to Hydraulic Fracturing Energy Model

The success of a hydraulic fracturing (HF) operation is strongly dependent on brittleness of the formation. Several models based on mechanical testing, mineral composition, and sonic log data have been proposed to quantify the brittleness of formations known as brittleness index (BI). The limitations of these conventional BI models, in particular, the consistency and applicability at field scale with the complex in situ conditions are poorly...
