This report presents a new practice for pressure transient analysis (PTA) and reservoir parameter estimation using system-identification (SI) techniques. The SI technique is widely used in advanced process engineering. The main goal of this study is to develop a reliable method for pressure transient analysis in horizontal wells benefiting from distributed pressure sensing. In addition, this technique is going to be used for the PTA of horizontal well data when the well is producing under choke control at surface. The ideas in this report are largely based on earlier work by Farshbaf Zinati  who developed a data assimilation approach to perform PTA using distributed sensing in horizontal wells, and and Mansoori  who pioneered the use of SI techniques for PTA. New elements in this report are the additional use of classic elements from (type-curve-based) PTA in the SI workflow and testing of the work flow with a synthetic example.
