HYDRAULIC FRACTURING

COURSE OVERVIEW

The course will cover all aspects of Hydraulic Fracturing including design, execution, post fracture evaluation, and economics of Hydraulic Fracturing. With a focus on applications, the course will cover sufficient details of theoretical aspects of Hydraulic Fracturing including geomechanics and fracture characterization using surface and bottomhole treating pressure. Variations in Hydraulic Fracturing from sandstone to carbonate and low to high permeability formations will be covered to provide a broad knowledge for practicing engineers. Recent advances in fracturing fluids, proppants, horizontal staged fracturing, and slick water fracturing will be covered including the benefits and limitations of these technologies.
