Overview of PNG 425

One of the major problems of petroleum engineering is to develop and apply methods and techniques to improve the capacity of wells to produce. The problem studied under the title of well testing is a localized problem where as any other reservoir engineering problem is concerned with the reservoir as a whole. In the development and application of well testing analysis techniques the preliminary aim is to come up with some practical methods which will enable the engineer in gathering accurate information about some physical reservoir parameters that play an important role on fluid flow dynamics in porous media. A properly developed numerical formulation is a critical facet of the methodology, which will be used in interpretation. Although, mathematics involved is relatively simple and straightforward a good understanding of the mathematical basis together with the physical laws that control the dynamics of fluid flow is essential. The solution of well testing model will either directly yield answers or provide some means to generate solutions to the well testing problem. The information gathered from a successful well test analysis includes reservoir pressure, formation permeability, reserve estimation, damage or stimulation in the immediate vicinity of the wellbore. All this well test derived information can be used to analyze, improve and forecast the potentials of the well and the formation hosting the well. This course is structured to equip the students with a wealth of information along these lines.
