Advanced Hydraulic Fracturing

Discipline

Production & Operations

Course Duration

5 days

Delivery Method

In-house

The course provides the knowledge and tools needed to design and analyze hydraulic and acid fracturing jobs. An overview of the fundamental of rock mechanics and its application to hydraulic fracturing will be presented. Then, the data requirements and various elements of massive hydraulic fracturing treatment design are covered in detail. Finally, the design of fracture treatment using analytical tools and commercial simulators is discussed in detail. The course concludes with a term project to design a fracturing treatment and evaluate the post treatment performance of the well.
