Wireline Formation Testing provides a comprehensive exploration of this modeling through use of hardware, advanced formation testing modules, and new interpretation techniques. Exposition of these analytical models, systematic inclusion of mixed boundary value problems, first-principle-based pressure gradient interpretation, probabilistic enumeration of radius of investigation, and system identification methods appeal to various levels of engineering expertise. This book provides a resource to experienced engineers who wish to evaluate reservoirs simultaneously with the scope of the testing results, as well as to universities that wish to provide students with this understanding through undergraduate and applied graduate courses.
