The main source of production interference is the Interactions that occur between multiple fractures in the same well (intra-well), and, in adjacent (inter-well) horizontal wells. These interactions can create indirect or direct hydraulic link between adjacent wells. Their effect on production can be immediate or delayed; depending on the type of the link. Other frequent consequences of these interactions are costly operational difficulties that occur during drilling, completion, and fracturing operations. Technically, the cause of these interactions is the stress changes that occur by the creation of hydraulic fractures, and, reservoir depletion. 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 horizontal wells include fracture shadowing, temporary frac-to- frac connections, long term frac-to- frac connections, and combinations of the them. Their consequence can be immediate or delayed production interference within adjacent wells. This course discusses how to identify the type of well-to- well interactions, their expected production interference, and completion and treatment steps that reduce their negative effects.

Detection, identification, 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.
