This course discusses the fundamental concepts and contemporary challenges associated with well performance using nodal system analysis approach. The course covers methods to govern Inflow Performance under the prevailing reservoir conditions taking into account the effects of stimulation, injection effects, completion design aspects, and horizontal wellbore effects. In addition, and importantly, an account of the problem well analysis and the constraints associated with Nodal analysis applications is discussed. The contemporary challenges are also pointed out. The course adopts a scaffolding approach where we apply our knowledge learnt from the simplest case to the more complicated applications. The learning outcomes will be assessed by a concept-oriented quiz at the end of each day’s session.
