Abstract-Hydraulic fracturing is a technique that increases the well deliverability and productive life of a well. Shale gas and light tight oil have low permeability, due to which they cannot be produced commercially. Fracture treatment is used to enhance their production. Hydraulic fracturing is the fracturing of rock by a pressurized liquid. A vertical well is drilled and multiple fractures are induced from the wellbore at various azimuths to produce artificial channels. To propagate the fractures, rods of perforate guns are lowered into uncased sections of the wellbore. These guns are then fired from the wellbore and holes are broken free and perforated during the production from the initial fracture. The injectivity test for hydraulic fracturing is conducted from the acquired wireline and/or petrophysical logs. This paper presents the case history of the optimization of hydraulic fracture treatments and performance of the fracture treatment of a shale gas well. The results show that the well deliverability and life have significantly improved after the treatment, saving millions of dollars of operational cost and also increasing the field productivity by 200%.
