Interactions between multiple fractures in horizontal wells is the main source of production interference between adjacent horizontal wells and cause immediate production re-routing and/or delayed production interference. The cause of these interactions is the stress change caused by the creation of hydraulic fractures and how they change the fracture growth pattern in different completion systems. This course offers a detailed systematic discussion of the various aspects of the subject.

Single well fracture interactions (intra-well). Course contents include detailed discussion of the causes of stress shadowing, Dynamic Active Fracture Interactions (DAFI) and activation of natural fractures, together with their impact on fracture growth pattern and well production.

Well-to-well fracture interactions )inter-well). Interactions between fractures in adjacent fractured horizontal wells include fracture shadowing, frac/frac connections, and combinations of the two. Their consequence can be immediate (production re-routing), or delayed production interference within adjacent wells. This course discusses how fracture interactions can cause these situations, and completion and treatment steps that reduce their negative effects.

Detection and evaluation of these interactions can also serve as a cost-effective frac diagnostic method for determination of critical fracture attributes such as length, orientation, and more. Course contents offer a comprehensive discussion of the subject, measurement techniques, and how to interpret the results.

Course contents are supported by actual field case histories.
